Exchanges and withdrawals
How to make a withdrawal
You can withdraw cryptocurrencies from your balance in two ways:

Cryptocurrency withdrawals

You have the possibility to transfer your cryptocurrencies to another exchange platform (e.g. Coinbase, Binance, Kraken,...) or to a hardware wallet (ledger, Ngrave,...) or an online wallet (metamask,...).

Withdrawals in euros (€)

You can request a withdrawal in €, directly to your bank account for the following currencies: BTC, ETH, USDT, USDC and DAI. The minimum amount for this type of withdrawal is €100.

A 2% fee is applied on € exchange transactions.

The procedure for making a withdrawal is very simple and takes only a few moments. Here are the steps to follow:

1. Go to the "my account" area.
2. Select the "Portfolio" tab.
3. Click on the "withdrawal" button at the currency you wish to withdraw. Add the RIB of the account to which you wish to withdraw your funds.
4. Indicate the amount you wish to withdraw and validate by clicking on "Request withdrawal".
Withdrawal period
The deadline for a withdrawal is 24 hours. Our withdrawals are made in chronological order of arrival, with a second manual validation to ensure maximum security.
What is a Memo
In some cases, for cryptocurrency withdrawals, you will be asked, in addition to your receiving address, for a memo. Indeed, some exchanges ask for it in order to identify the recipient account. You will find this memo directly on the exchange on which you wish to send the funds. If in doubt, please contact our team.
Make an exchange
You have the possibility to make intercryptomurrency exchanges directly on our website. Please note that this feature is not available for all crypto-currencies. Indeed, only crypto-currencies with sufficient liquidity on the markets are eligible.

Here are the steps to follow to make a trade:

1. Go to your dashboard.
2. Select the "Portfolio" tab.
3. Click on the "exchange" button at the currency you wish to withdraw.
4. Enter the amount you wish to exchange and the final currency.
5. Validate by clicking on "validate exchange".

Thanks to our collaboration with Veraone, you can also transform your cryptocurrencies into gold directly on our platform.
Fees
Fees vary depending on the crypto-currencies and their liquidity. The details of these fees being described in our Fee Policy, and will be reminded to you upon trade execution.

Disclaimer: In the absence of legal and regulatory definitions for certain terms to date, the definitional efforts within this FAQ by Just Mining, are made in good faith. As such, these descriptions and explanations are subject to change as legal and regulatory developments occur.
What is DeFi (Decentralized Finance) ?
DeFi or Decentralized Finance refers to all financial applications and services using the Blockchain to carry out exchange, transmission or value creation operations, requiring no or few intermediaries.
What is CeFi (Centralized Finance) ?
The BeCeFi called "Centralized Finance" designates all the financial applications and services realized with the help of trusted third parties (example: Just-Mining, Binance, Nexo...)
What is a stablecoin?
The term stablecoin refers to a crypto asset issued on the blockchain, whether by a regulated entity, a decentralized autonomous organization (DAO) or a decentralized finance protocol (DeFi). Their value is most often backed by a fiat currency, such as the dollar or the euro. In some cases, they may be more tangible assets of traditional finance, such as gold, for example.

The parity between the stablecoin and its underlying can be maintained through various mechanisms (collateralization, algorithm ...).
What are the risks associated with stablecoins?
Although stablecoins are regularly considered as assets to secure one's positions or de-expose oneself they are not without risks.

The main risks to which stablecoins are exposed are the following (non-exhaustive list):

• Counterparty risk (issuer of the stablecoin)
• Technology risk
• Volatility risk
• stablecoin liquidity risk
• Systemic risk
• Economic and financial environment risk
What is the Peg?
The Peg represents the parity established between an asset and its underlying. In particular in the case of stablecoins backed by the US dollar, it is accepted that one token is equivalent to one dollar. By extension, we call de-peg the loss of parity that an asset can suffer in relation to its underlying.
What is a DeFi protocol ?
It is the technical infrastructure that allows the implementation of decentralized tools such as liquidity pools, loan systems and decentralized applications (e.g. AAVE, Curve, Pancake Swap...).
What is a compounder?
It is an overlay of a protocol allowing the increase of the yields via the optimal use of the mechanisms of this protocol (ex: Convex, StakeDAO...). For example, Convex and StakeDAO are compounders of the Curve protocol.
What is a liquidity pool?
A liquidity pool is a reserve of liquidity locked in a smart contract and available to users and protocols of decentralized finance.

These liquidity pools allow, in particular, to ensure exchange, loan and borrowing operations of the funds available on them, at any time and without a trusted third party. They are the central element of the DeFi ecosystem.

Anyone who can contribute liquidity to a pool. He receives in exchange an LP tokens that represents the asset(s) deposited in this pool.
What is the role of a liquidity pool?
Unlike centralized finance (CeFi), decentralized finance (DeFi) does not operate on the basis of order books. Liquidity pools thus ensure instant availability of funds to execute financial transactions.

Typically, exchange transactions are carried out using AMMs (Automated Market Makers). These are computer programs that manage the exchange rate between two assets based on a mathematical formula and the liquidity available in the pool in question.
What is an LP token?
An LP token (Liquidity providing token) is a token received in exchange for the liquidity provided to a pool, in proportion to the total liquidity of the pool. The instantaneous value of an LP token is equal to the division of the total value of the assets contained in the pool at time T by the total quantity of LP tokens at that same time.

The value of this LP token can vary in different ways, including:

• Via the fees generated by the exchanges made using the liquidity made available by this pool.
• The loss/gain of value of assets constituting the pool (Impermanent loss).

This LP token also allows the withdrawal of liquidity in proportion to the value of the LP token at the time of withdrawal.

Example:

Paul decides to deposit 500 USDT and 500 USDC into a liquidity pool containing 49,500 USDT and 49,500 USDC. At that instant, 1 USDT = $1 and 1 USDC = $1. In proportion to his deposit in the pool, he receives 1,000 LP tokens in exchange.

A few weeks pass, users are using the liquidity pool to trade, generating fees that are built into the liquidity pool as compensation. Paul decides to withdraw his liquidity. At this point, the pool consists of 50,200 USDT and 49,900 USDC which represent 100,000 LP tokens distributed among the various liquidity providers in proportion to the share of the total liquidity they contributed.

At this point, 1 USDT = $0.997 and 1 USDC = $1.003.

Paul's 1,000 LP tokens therefore represent 502 USDT and 499 USDC, for a value at that moment of $1,001
What is Impermanent Loss (IL)?
Impermanent Loss is the loss at time T caused by a change in the value of one or more assets in the liquidity pool.

Impermanent Loss can only occur within a pool of at least two different crypto assets. This means in plain English, that by withdrawing the liquidity contributed to this pool, it is possible that the value of the funds withdrawn will be less while the amount of cryptoassets withdrawn will be more than the amount initially deposited.

Example:

In this example, we will contrast the strategies of Paul and Peter. Paul decides to keep his cryptocurrencies in his wallet while Peter decides to use liquidity pools. Let's say that one ETH = $2,000 and 1 USDT = $1

Paul has one ETH that he keeps on his Hardware Wallet.

Peter on the other hand deposits 1 ETH which he deposits on a liquidity pool containing ETH and USDT. He receives in exchange 1 LP token representing 1% of the total liquidity of the pool which is 50 ETH and 100,000 USDT (we recall that the purpose of a liquidity pool is to maintain a balance of value between the different cryptoassets that comprise it).

Now let's assume that ETH is valuing and its price is now at $4,000. The USDT price, is still at $1.

Paul, who keeps his ETH on his hardware wallet, still has one ETH which is therefore worth $4,000.

Peter, however has one LP token still representing 1% of the liquidity pool which itself in order to maintain a balance now has 37.5 ETH and 150,000 USDT.

On this basis, Peter would have if he decided to withdraw his liquidity from the pool 0.375 ETH and 1500 USDT, or a total of 0.75 ETH ($3,000). Peter thus lost 0.25 ETH compared to Paul.
What is the difference between RPA and PYA?
• The APR (Annual Percentage Rate) is the annualized gross interest rate.
• The APY (Annual Percentage Yield) is the annualized gross interest rate, adding back interest, at a defined interval.
What is Lending?
Generally speaking, Lending consists in carrying out lending-borrowing operations of crypto assets within decentralized finance (DeFi).

By extension, the Lending service as offered by Just Mining brings together lending-borrowing and liquidity providing/yield farming activities on decentralized finance (DeFi) as well as the use of centralized platforms (CeFi) in order to generate a return on deposited crypto assets.
How does Just Mining's stablecoin lending service work?
Just-Mining's Lending stablecoins service is a service designed on a risk-based approach and not on a return-based approach. Thus, we do not seek to maintain a fixed performance, rather we seek to maintain a consistent balance between exposure and risk. When you subscribe to Just Mining's Lending stablecoins you are instructing Just Mining to invest your crypto assets according to the following components:

Component 1: Diversification across protocols, compounders and CeFi platforms

Currently, Just Mining offers diversification across the following protocols, DeFi (decentralized finance) compounders and CeFi (centralized finance) platforms, as per our terms and conditions:

DeFi Protocols: AAVE, AAVE AMM, Compound, Curve, PancakeSwap, SushiSwap
Compounders (DeFi): Convex, StakeDAO
CeFi platforms: Binance, Nexo, Woorton

Just Mining will not place more than 30% of Cryptoassets on a single DeFi/compounder protocol in an effort to mitigate counterparty risk. In addition, exposure to CeFi platforms as a whole is limited to 40%.

Component 2: diversification of stablecoins

The diversification of the counterparties used also involves a conversion of the subscription stablecoin into one or more of the following cryptoassets:
• BUSD (Binance USD)
• DAI (Dai)
• FRAX (Frax)
• GUSD (Gemini Dollar)
• SUSD (sUSD)
• TUSD (TrueUSD)
• USDC (USD Coin)
• USDP (Pax Dollar)
• USDT (Tether)

In the case of using CeFi platforms, since the actual distribution of the deposited stablecoin is not communicated by them, we can only assume that this stablecoin is not converted by the platform in question. Regardless of which stablecoin you subscribe to our lending service with (investment or deposit), your capital is diversified among several of these stablecoins (note: diversification is not necessarily done on all stablecoins at all times).

Component 3: maximum exposure to a stablecoin

The notion of maximum exposure to a stablecoin is a factor determined by projecting oneself into a scenario in which all the liquidity pools containing that stablecoin in question would be totally unbalanced as well as all the funds deposited on the CeFi platforms (whose actual distribution we do not know). Thus, this is the maximum possible exposure to each stablecoin taking into account the distribution of protocols, compounders and CeFI platforms at the time of the calculation.

Let's take the following diversification:

• 30% of the funds placed on a USDT-USDC pool
• 15% on a USDT-DAI-USDC pool
• 25% on a pool containing only DAI
• 10% in USDP and 10% in TUSD on a CeFi platform (whose asset diversification we do not know)
• 10% in BUSD on a CeFI platform (whose asset diversification we know)

The assumed maximum exposure to each stablecoin would be as follows:

• 60% DAI
• 65% USDC
• 65% USDT
• 20% USDP
• 20% TUSD
• 30% BUSD
How does Just Mining's ETH lending service work?
Just Mining's ETH Lending service is a service designed on a risk-based approach and not a return-based approach. Thus, we do not seek to maintain a fixed performance, but rather to maintain a consistent balance between exposure and risk. When you subscribe to Just Mining's ETH Lending service you are instructing Just Mining to invest your Crypto assets according to the following components:

Component 1: Diversification of protocols, compounders and CeFi platforms

Currently, Just Mining offers diversification across the following protocols, DeFi (decentralized finance) compounders and CeFi (centralized finance) platforms, as per our terms and conditions:

DeFi Protocols: AAVE, AAVE AMM, Compound, Curve
Compounders (DeFi): Convex, StakeDAO
CeFi platforms: Binance, Nexo, Woorton

Just Mining will not place more than 40% of Cryptoassets on a single DeFi/compounder protocol in an effort to mitigate counterparty risk. In addition, exposure to CeFi platforms as a whole is limited to 40%.

Component 2: Diversification of Crypto-assets

The diversification of the counterparties used also involves a conversion of the Subscription Crypto-asset into one or more of the following Crypto-assets:

• ETH
• sETH
• stETH
• WETH

In the case of using CeFi platforms, as the actual distribution of the deposited Crypto-asset is not communicated by them, we can only assume that this Crypto-asset is not converted by the platform in question. Whether you subscribe in fiat or ETH (investment or deposit), your capital is spread across several of these Crypto-assets (note: diversification is not necessarily done on all Crypto-assets at all times).

Component 3: maximum exposure to a Crypto-asset

The notion of maximum exposure to a Crypto-asset is a factor determined by projecting oneself into a scenario in which all the liquidity pools containing that crypto-asset in question would be totally unbalanced as well as all the funds deposited on the CeFi platforms (whose actual distribution we do not know). Thus, this is the maximum possible exposure to each Crypto-asset taking into account the distribution of protocols, compounders and CeFI platforms at the time of the calculation.

Let's take the following diversification:

• 20% of the funds placed on an ETH-stETH pool
• 20% on an ETH-sETH pool
• 30% on a pool containing only ETH
• 30% in ETH on a CeFi platform (whose asset diversification we do not know)

The assumed maximum exposure to each crypto asset would be as follows:

• 100% ETH
• 50% stETH
• 50% sETH
In what situation can the maximum exposure be reached?
There are several cases that can lead to maximum exposure to a crypto asset, including:
• The loss of value of one of the cryptoassets that leads to an imbalance in quantity (cryptoassets) of the pools in which it is contained
• The withdrawal or mass deposit by liquidity providers of one of the assets contained in the pool
How are the proposed DeFi protocols, compounders and CeFi platforms selected ?
There are thousands of DeFi protocols, compounders and CeFi platforms available today. Of course, not all of them have the same characteristics and do not present the same level of risk. At Just Mining, we select DeFi protocols, compounders and CeFi platforms based on a risk-based approach. These are the same factors that also allow us to measure the level of exposure we offer on a DeFi protocol, compounder and CeFi platform.

Here is the list of factors we pay particular attention to:

• The total liquidity deposited on the protocol, compounder, liquidity pool, CeFi platform (TVL)
• The proposed returns
• The sources of returns (mechanisms used)
• The blockchain network on which the pool is based
• The reputation of the protocol, compounder or CeFi platform
• The available technical audits
What are the risks associated with lending?
Just Mining uses various decentralized finance protocols and compounders and centralized platforms. These protocols, coumpounders and platforms (CeFi) are independent from the control of Just Mining which could not be held responsible for their potential flaw.

The main risks to which this service is exposed are the following (non-exhaustive list):

• Counterparty risk related to the failure of DeFi protocols and compounders (decentralized finance) and CeFi platforms (centralized finance).
• Risk related to the use of one of the blockchains (in particular the failure of one of the blockchains used)
• Risk of volatility of the crypto assets contained in the diversification of the service
• Risk of loss of parity (de-peg) of the cryptoactives contained in the diversification of the service
• Risk related to the liquidity of the cryptoactives
• Risk of loss of funds (including hacking)
• Risk related to the economic and financial environment
How is the interest paid?
Interest is credited to your lending contract in the form of LP tokens and can be claimed at any time or automatically reinvested via the compound interest feature.

Until claimed, the value of the interest received in LP may vary, depending on the diversification of the lending service at the time.

You can claim your interest by clicking on the "Claim" button on your lending contract. You will then be able to select the stablecoin of your choice, taking into account the value of the LP token in relation to the withdrawn token at that moment.
How do I get out of Lending?
You can retrieve your crypto assets by clicking on the "Withdraw" button on your lending contract. You will be able to select the stablecoin of your choice, taking into account the value of the LP token in relation to the token you are withdrawing at that moment (note that a retribution period may be applied, which is displayed on the product page as well as during the withdrawal process)
How does Just-Mining pay?
The APR received by our clients on the Lending offer is net of fees. Just-Mining is thus remunerated thanks to the surplus generated compared to the distributed yield.

Generally speaking, this remuneration does not exceed 2% gross knowing that Just-Mining takes in charge all the costs inherent to the execution of the client's orders. As an indication, we receive a net margin varying on average between 0.8% and 1.5%.
How are my tokens secured?
All funds arranged on DeFi protocols and compounders are stored with the help of multi-signature services which are used to achieve increased security. In the case of CeFi platforms, the storage and security of funds is ensured by the platform in question.
Staking
What is staking?
Staking is a validation mechanism that consists in immobilizing a quantity of crypto-currencies in order to obtain interest. This system, in its operation is close to that of a savings account while offering more interesting prospects of return.

Read our article What is staking?
What crypto currencies are available for staking?
The list of crytomoney as well as upcoming availability is directly available on the staking page.
Why is it worthwhile to do staking?
Staking allows you to earn interest from your cryptocurrencies. If you don't have the skills or time to do it, our service allows you to grow your wealth passively.
How much can I earn with staking?
Depending on the project, the annual interest rate (APR) can vary from 5 to almost 50%. The list of different APRs is available directly on the staking page. Please note that these APRs are not fixed, they may change over time according to the rules defined by the projects.
How long does it take to activate my staking?
The staking starts 24 hours after the order.
How do I get my staking earnings back?
Staking earnings are credited at regular intervals in cryptocurrencies directly to your Just Mining customer area. Conditions may vary depending on the project. All these features are displayed on the staking product page. Once your earnings are on your balance, you are free to withdraw them whenever you want. You also have the option to exchange your earnings for other crypto-currencies or reinvest your interest to generate even more tokens.
When can I stop my staking?
You are free to request the withdrawal of your crypto-currencies whenever you want. Some projects may have specific deadlines to be able to retrieve your tokens, these deadlines are displayed in the conditions of each staking contract. This is called the unstaking period.
What are the additional costs?
A service fee is applied to our staking service. These fees are variable for each project and are indicated directly on the product page.
How do I make a deposit?
It is possible to deposit your own tokens to initiate a staking/lending contract. Go to the product page and click on DEPOSIT
What are the risks?
The main risk is market volatility. Cryptocurrencies are volatile investment products. Investment always rhymes with risk. It is this risk that makes this form of investment interesting.
How are the staking offers displayed on our site selected?
Each project listed on our platform must meet a certain number of requirements. A work of analysis is carried out during several weeks to several months before a project appears in our catalog.

This selection is based on several criteria The fundamentals: the project, the team and the community The market: available cash and partner exchange platforms
Technical: complexity of implementation, node management, compatibility with our security department requirements.

Most of the time, Just Mining becomes a technical partner of the project by operating for the proper functioning of its network. This technical collaboration allows us to be closer to the project and to better control its operation.
When are the fees on staking deducted?
The fees on staking are deducted at source. This means that anything you receive on your wallet is yours and there will be no other fees on it.
The amount of fees varies from project to project. This information is available directly on the staking page.
Why do I need a shipping address for a staking or lending order?
As the staking is a totally dematerialized product, you will not receive anything physical at your address. However, it is essential to provide an address for billing. That's why we ask you for an address when you order.
What is RPA and how is it calculated?
APR is the annual interest rate. The APR is applied to the tokens and not to the amount in € invested at the beginning.
Example: You buy 100 MATIC on 01/01/2020. The APR of MATIC is 38%. If it remains fixed throughout the year, on 01/01/2021, your investment will have generated 38 MATIC of interest (38% of the initial 100 MATIC). Interest is credited every minute except for ICON (every 24 hours) and SNX (every 7 days).
Masternodes
Definition
Literally, a masternode is a network node that performs different tasks on a blockchain. To illustrate, let's compare the masternode system to an enterprise structure.
In this situation, the enterprise as a whole represents the cryptocurrency. The president of this company is the Blockchain, he is the one who is responsible for running the company by making the essential decisions for its development and setting up rules to follow.

The masternodes are the team leaders who have to complete a mission in order to be able to move the company forward. Each mission completed correctly will be recorded on the Blockchain. The employees are the nodes who are responsible for completing the task requested by their superior. If the job is done correctly, then the masternode will be able to forward the information to the next level.

Read our article what is a masternode?
Glossary
Reward: these are the rewards, the tokens you receive.
Collateral: this is the amount of tokens needed to make up a masternode.

This collateral is recoverable, you remain the owner. The only exception to this rule is the Sinovate project.
What is it for?
The Masternodes are used to secure a Blockchain. There are different ways to secure a Blockchain. Mining is the best known activity but it is not the only one.

On this blockchain, masternodes are used in particular to anonymize and perform instant transactions on the network and also give a right to vote in order to participate in the decisions taken in a decentralized way.
After how long is my masternode activated
After your order, your masternode is activated within 72 hours.
Interests
Interest is applied to your collateral, not its value in euros.

For example:
The masternode Polis consisting of 1,000 Polis tokens with an interest of 26%*. At the end of the year, you will get 260 Polis. However the value of these tokens will depend on the Polis price.

*This APR is indicative
Can I resell my collateral?
You can sell your collateral whenever you want. You are the owner of your masternode, you are free to sell your tokens at any time without any additional cost. (Except for the Sinovate project whose collateral is burned)
Can I bring my own collateral?
From a certain amount, we can accept your own tokens. Contact an advisor for a customized offer. (apply)
How are the masternodes selected on our site?
As for the staking projects, the masternodes listed on our site are selected according to several criteria. An analysis is done before each listing.

This selection is based on several criteria The fundamentals: the project, the team and the community
. The market: available cash and partner exchange platforms
Technical: complexity of the implementation, node management, compatibility with our security department requirements
If you are interested in a masternode that is not offered on our site, you can request a quote from our teams. Technically, we are able to install any masternode.
What is the difference between full and shared masternodes?
Integral Masternodes: you own the entire node.
SharedMasternodes: you only own a fraction of the node. It makes no difference to the user. Whether you invest in full or shared masternodes, you get the same functionality.
Will several shared masternodes merge?
No, if you place multiple orders for the same masternode on different dates, each shared masternode will appear as a separate contract. Rest assured that whether you have 1 full masternode or 2 times 50% of a masternode does not change your performance at all.
Fees
Fees of 5% are charged on the performance of the masternodes in real time. These fees cover the maintenance of the node, the servers and the custody.

Installation fees are already included in the price displayed on the site.
Why am I asked for a delivery address?
Since masternodes are totally dematerialized products, you will not receive anything physically at your address. However, it is essential to provide an address for billing. That's why we ask you for an address when you order.
Why do I get bills every month?
These invoices correspond to the 5% fees that are applied to the rewards of the masternodes.
Is there a resale fee for masternode?
No, you can resell your masternode whenever you want without any fees.
Parachains
What are parachains?
Parachains are secondary chains to an infrastructure blockchain, which can evolve into a dedicated slot within it.

Parachains have been implemented for the Polkadot and Kusama ecosystems.

Polkadot and Kusama are infrastructure blockchains that offer a technology foundation that can be leveraged by other projects. Projects intending to build on this foundation will need a Parachain slot within the Polkadot or Kusama blockchain infrastructure to deploy.

These slots are limited. To avoid inequality, Polkadot's teams have implemented an allocation system that you'll learn about below.
How do the parachains work?
Thus, during a parachain auction, it is the DOT or KSM holders (depending on whether it is on Polkadot or Kusama infrastructure) who will choose the allocation of slots by depositing their DOT or KSM in favor of the project of their choice. For the Polkadot Parachute Auction, you - Just Mining customers - can place your DOT tokens on the project(s) you wish to support.
Why participate in a parachain?
Participating in a parachain allows you to receive in return new tokens from the project you support, if it wins the auction. As an investor, this system allows you to position yourself early on young ambitious projects.

Note that the DOTs you place are not spent. They are locked in a smartcontract. They will be returned to you after the auction, if the project for which you have deposited your DOTs did not win the auction. Otherwise - in case the project for which you placed your DOTs won the auction - your DOTs will be returned to you after a blocking period (the period varies by project).
How is the winner of the parachain determined?
At the end of the auction period, a specific time is randomly determined. The project with the most DOTs at this precise moment wins the auction.

Please note that once you have placed DOTs on a project, you cannot withdraw them during the auction, you must wait for the end of the blocking period previously foreseen by the project or the end of the auction if your project has not won the auction. Just Mining can in no way guarantee the success of the projects listed.
What happens to my DOTs if the project wins the Parachain auction?
If the project on which you have positioned yourself wins the auction of the parachain, you will be eligible for the distribution of new tokens according to the rhythm previously defined by the project. Concerning your DOTs, they will be blocked for a predefined period. At the end of this period, they will be credited (in full) to your Just Mining wallet. The maximum blocking period is known before the start of the parachain auction.
What happens to my DOTs if the project does not win the Parachain auction?
If the project on which you have positioned yourself does not win the auction, all your DOTs will be returned to your Just Mining wallet within 24 hours of the results.
How much can I earn with parachains?
We cannot determine in advance the profitability associated with a successful Parachain auction. New tokens will be released by the projects that won the Parachain auction at a rate determined before the auction. They will be shared among all contributors who deposited their DOTs in favor of the project that won the Parachain slot. We cannot know in advance how many contributors will participate in the Parachain auction.

Similarly, we cannot know at what price the new token will be listed.

Financial gains at the end of the Parachain auction, will vary depending on the number of tokens distributed and the volatility of the prices of the tokens in question.
How does Just Mining make money on the operation?
Just Mining is remunerated by keeping 5% of the new tokens issued by the project(s) that won the parachain. No fees are applied if the project did not win the parachain auction. In all cases, no fees will be applied on the return of your DOTs.

Ex: You deposited 50 DOTs in favor of project X. The project in question won the parachain auction. According to the distibution conditions of project X, with this level of contribution, you are eligible for 100 tokens. You will receive 95 tokens and Just Mining will keep 5. Your 50 DOTs will be fully credited to you at the end of the blocking period defined by the project.
What are the risks of participating in a parachain event?
Participation in a parachain auction involves two things: holding DOT tokens and tying them up for a pre-determined period of time.

Thus, you must accept exposure of your capital to the volatility of the DOT during this period.
Can I participate in several parachains?
Yes, it simply involves having multiple DOTs.

A DOT can only be filed in support of one project.
In case of success, what happens to the distribution of the tokens?
Just Mining applies a pro-rata distribution system. In order to simplify operations, we will not take into account specific distribution characteristics (e.g. the first contributors to the auction receive more tokens).

Thus, in some special cases, you may receive less tokens via Just Mining than by participating directly in the Parachain auction on your own.
What is a crowdloan?
A crowdloan is a way for new projects to get support from its community through the allocation of DOTs in order to win a parachain site. The term can be misleading, as you are not actually "lending" funds to projects. Your DOTs are simply tied up over a longer or shorter period of time depending on the outcome of the auction.
Mining - ASICs
How to calculate the profitability of a machine?
The profitability of a machine depends mainly on 3 factors:
- The price of the crypto-currencies: naturally, if the calculation is made when the bitcoin is at 30000€ or at 15000€, the results are different.
- The difficulty: it is the number of miners on the network. Indeed, the rewards of mining are shared among miners. The more miners there are, the greater the difficulty and the smaller the amount of cryptocurrencies mined.
- The cost of electricity: machines are energy intensive. It is decisive for a miner to pay for his energy as cheaply as possible in order to optimize his output.

As you have understood, among these 3 factors, the only one that can be accurately anticipated is the cost of electricity. The first two are very variable and depend on the market, it is difficult to measure accurately over time.
In these conditions, it is possible to calculate the profitability of a machine at the moment T but be careful to duplicate this result in time does not allow to obtain the exact profitability.

You can realize this type of calculation on online calculators like coinwarz. Select the SHA-256 algorithm for a Bitcoin machine or Ethash for a machine that mines ETH. Fill in the fields according to the power of the machine, its consumption and your electricity rates. If you have any difficulties in performing this calculation, please do not hesitate to contact our team.
Are the machines noisy?
The asics are particularly loud machines. Installing a mining machine in your home is not really suitable. Although the level of nuisance is up to each individual's interpretation, it is not advisable to install this type of equipment in a living room. It is best to place them in a dedicated room, garage or other secluded area.
I want to set up a mining farm, how do I go about it?
Every mining farm project is different. It is defined on a case by case basis depending on your arrangements. We invite you to contact our teams to determine the key points for the success of your project.

Cloud Mining
What is cloud mining?
The cloud mining is a system for renting computing power. Mining due to its energy requirements in particular is not viable for most people. Also, cloud mining makes mining accessible to all, mining without its constraints.
How to calculate the profitability of cloud mining?
The profitability of a machine depends mainly on 2 factors:
- The price of the crypto-currencies: naturally, if the calculation is made when the bitcoin is at 30000€ or at 15000€, the results are different.
- The difficulty: it is the number of miners on the network. Indeed, the rewards of mining are shared among miners. The more miners there are, the greater the difficulty and the smaller the amount of cryptocurrencies mined.
These factors are variable over time and in this way, we cannot anticipate with great accuracy the profitability of cloud contracts over time. Nevertheless, it is possible to calculate the profitability of a contract at the moment T thanks to tools like coinwarz.
What are the costs associated with the cloud mining contract?
For all our cloud mining contracts, you pay only once the price displayed on the site for the duration indicated. There are no other fees applied.
What is 1 HRT?
The THS is the power unit of mining. It corresponds to the capacity of the machine to make calculations. The THS is to mining what the KM/h is to speed.
