Cloud mining is a process of mining cryptocurrencies like Bitcoin, Ethereum, and many more, by using resources of distant centres. Simply said, this type of mining allows users to rent mining hardware from a third-party provider to mine cryptocurrencies without the need for them to purchase or maintain the equipment themselves.
In cloud mining miners use shared processing power that is hosted in a remote data center. Everything needed is an internet connection, without any specialized mining equipment or infrastructure, and funds in crypto (to pay for services) to start mining cryptocurrencies.
Key players in cloud mining include mining pool operators, hosting providers, and cloud mining companies. Some of the most popular cloud mining companies include Genesis Mining, StormGain, ECOS, and Eobot.

Understanding Bitcoin Cloud Mining
Bitcoin mining is the process of verifying and adding new transactions to the blockchain, which is the decentralized ledger that records all Bitcoin transactions. It is also the process of creating new Bitcoins.
Here are the basic steps how cloud mining works on the Bitcoin network:
- Transactions’ verification: Miners receive a new transaction or a block of transactions to be verified by checking whether the sender has sufficient funds and whether the transaction is valid.
- Block creation: Once the verification is complete, miners create a new block of transactions that they want to add to the existing blockchain database. This block contains a list of all the verified transactions and a unique code called a “hash.”
- Solving the hash puzzle: Miners use powerful computers to solve a complex mathematical calculation to create a new hash for the block.
- Adding a new block to the blockchain: Once the equation is solved, the miner broadcasts the new block and its hash to the entire Bitcoin network. The other nodes on the network then verify the block and add it to the blockchain. Node operators can also reject it if they find it invalid.
- Reward: The miner who successfully solved the hash puzzle is rewarded with a newly minted Bitcoin.
When choosing a Bitcoin cloud mining provider, it is important to consider the following factors:
- Reputation: Choose a provider with a good reputation in the market, and make sure to check reviews and ratings of the provider on different platforms.
- Hash rate: The higher the hash rate, the more mining power the provider can offer, which will result in higher rewards.
- Fees: Look for a provider with reasonable fees. Make sure that there are no hidden charges that might be added later.
- Contract length: Consider the length of the contract. Some providers offer short-term contracts, while others offer long-term contracts. Choose a provider that suits your needs and budget.
- Maintenance fees: Check whether the provider charges maintenance fees. Some providers charge a percentage of the mining rewards as maintenance fees, which can affect your earnings.
- Transparency: Choose a provider that is transparent about its operations, especially about hardware specifications of the equipment used for mining.
- Security: Check whether the provider has proper security measures in place to protect your investment and data, they are GDPR compliant.
- Customer support: Choose a provider that offers good customer support. Look for a provider that is available 24/7 and has multiple support channels.
- Mining algorithm: Check whether the provider offers mining for the algorithm you are interested in. Different algorithms have different rewards and difficulty levels.
- ROI: Consider the return on investment that the provider can offer. Look for a provider that can offer a good ROI based on the current market conditions.
How Cryptocurrency Mining Works
Cryptocurrency mining is a process of validating transactions on a blockchain network by solving complex mathematical equations and adding new blocks to the blockchain.
The first miner to solve this mathematical problem gets to add a new block to the ledger and is rewarded with the newly created coins for this operation. As mentioned before, it is completely legal and can be economically valuable.
Here’s how cryptocurrency mining works:
- Verification of transactions: Whenever a cryptocurrency transaction is made, it is broadcasted to the network for verification. Miners then compete to validate and add it to the blockchain.
- Proof of Work: The process of solving complex mathematical equations is called Proof of Work (PoW). It requires a lot of computational power and energy.
- Mining reward: Once a miner solves a task, he adds a new block to the blockchain, and receives a reward in the form of newly minted cryptocurrency.
- Difficulty adjustment: To ensure that new blocks are added to the blockchain at a consistent rate, the difficulty of the mathematical equations is adjusted periodically based on the number of miners and the overall network hash rate.
- Transaction fees: In addition to the mining reward, miners also earn transaction fees for validating transactions on the blockchain. These fees are paid by the users who initiate the transactions.
- Mining pools: To increase their chances of earning mining rewards, miners often join mining pools where they pool their resources and work together to solve the equations and earn rewards.
There are different types of cryptocurrencies that can be mined, and the most popular are:
- Bitcoin (BTC): Bitcoin is the first and the most popular cryptocurrency. It uses the SHA-256 algorithm for mining and has a limited supply of 21 million coins.
- Ethereum (ETH): Ethereum is a decentralized platform that enables smart contract creation as well as programming decentralized applications (dApps). It uses the Ethash algorithm for mining. ETH is its native cryptocurrency used to pay for fees when communicating with the Ethereum network.
- Litecoin (LTC): Litecoin is a peer-to-peer cryptocurrency that uses the Scrypt algorithm for mining. It was created to improve on some of the limitations of Bitcoin, such as transaction speed and scalability, mainly on the decentralization costs.
- Bitcoin Cash (BCH): Bitcoin Cash is a fork of Bitcoin that was created to increase the block size limit, allowing for faster and cheaper transactions. It uses the SHA-256 algorithm for mining. Similar to Litecoin, this fork caused less decentralization, and therefore bigger control of the network by certain individuals.
- Monero (XMR): Monero is a privacy-focused cryptocurrency that uses the CryptoNight algorithm for mining. It is designed to be untraceable and unlinkable, providing users with complete privacy. By far the most popular privacy-oriented coin.
- Zcash (ZEC): Zcash is another privacy-focused cryptocurrency that uses the Equihash algorithm for mining. It allows users to send private transactions by using a technology called zk-SNARKs.
- Dash (DASH): Dash is a cryptocurrency that offers instant and private transactions. It uses the X11 algorithm for mining.
The list is not final, of course. The type of cryptocurrency that can be mined depends on the mining hardware and software used, as well as the algorithm and the blockchain network.
Mining pools are basically groups of miners who work together to increase their chances of solving the complex mathematical equations required to add new blocks to the blockchain and earn cryptocurrency rewards. The role of mining pools is to make the mining process more efficient, cost-effective, and profitable for the individual miners.
Here are some of the benefits of mining pools:
- Increased hash rate: By pooling their resources, miners can increase their combined hash rate, which is the computational power required to solve the equations and add new blocks to the blockchain. This increases the chances of earning rewards.
- Consistent rewards: Mining pools distribute the rewards earned among the participating miners based on their contribution to the pool. This provides miners with a more consistent stream of income as compared to solo mining, where the rewards are less frequent.
- Lower costs: Mining pools help reduce the costs associated with mining by sharing the expenses of electricity, cooling, and maintenance among the participants.
- More stable network: Mining pools help create a more stable and secure network by ensuring that no single miner or group of miners controls a significant portion of the hash rate, which could potentially lead to network manipulation or centralization.
Overall, mining pools play a crucial role in cryptocurrency mining by providing miners with a more reliable and profitable way of earning rewards.
Cloud Mining Models and Types
There are generally three types of cloud mining contracts that are offered by cloud mining providers:
- Hosted mining: Hosted mining is a type of cloud mining contract where the mining hardware is owned, maintained, and hosted by the cloud mining provider. The user leases the mining power from the provider, and the rewards earned from mining are shared between the provider and the user.
- Virtual hosted mining: Virtual hosted mining is similar to hosted mining, except that the user leases virtual mining hardware instead of physical hardware. This means that the mining hardware is simulated, and the user does not have access to the physical hardware. The rewards earned are shared between the provider and the user.
- Leased hashing power: Leased hashing power is a type of cloud mining contract where the user leases a certain amount of hashing power from the cloud mining provider. The user can then use this hashing power to mine the cryptocurrency of their choice. The rewards earned from mining are sent directly to the user’s wallet, and the user pays a fee to the provider for leasing the hashing power.
Factors to consider when choosing a cloud mining contract would be that contracts can vary significantly in terms of fees, contract length, and the cryptocurrency that can be mined.
Therefore, if you wish to participate in cloud mining, do a proper research and compare different cloud mining providers to find the one that best suits your needs and budget.
Here’s a comparison of different cloud mining models:
| Aspect | Hosted Mining | Virtual Hosted Mining | Leased Hashing Power |
|---|---|---|---|
| Ownership | Hardware is owned and maintained by the provider. | No physical hardware owned by user. | No physical hardware owned by user. |
| Equipment Costs | No upfront costs for user. | No physical hardware owned by user. | Leasing fees required. |
| Technical Skills | No technical skills required. | No technical skills required. | Some technical skills required. |
| Control | Limited control over the hardware. | No control over the hardware. | Full control over mining software and pool settings. |
| Profit Sharing | Rewards earned are shared with the provider. | Rewards earned are shared with the provider. | User keeps all rewards earned. |
| Maintenance | Provider handles maintenance and repair issues. | No physical hardware to maintain. | User responsible for setup and management. |
| Profitability | Profitability may be lower due to sharing of rewards. | Profitability may be lower due to sharing of rewards. | Profitability depends on mining difficulty and leasing fees. |
In general, leased hashing power offers users the most control and flexibility over their mining activities, but it also requires the most technical knowledge and upfront investment.
Hosted mining and virtual hosted mining are more accessible to beginners, but they offer less control over the mining process and can be less profitable due to the sharing of rewards with the provider.
It is important to consider your individual needs and preferences when choosing a cloud mining model.
