cloud mining-Облачный майнинг

 Having figured out how mining works, you can try another method that is available to almost everyone and has a minimum entry threshold. The advantages of the technique are that there is no need to buy expensive equipment, set it up and endure a high noise level.

Therefore, a beginner and even an experienced miner should carefully select services. And in 2021, among the best options you can find such sites:

ECOS, for Bitcoin mining;

BeMine - for mining Bitcoin, Zcash and Ethereum;

Genesis Mining, for mining a variety of cryptocurrencies, from Bitcoin and Dash to Zcash and Litecoin.

(Genesis Mining), and for 8 months (BeMine). But it is worth considering - the longer the contract, the more the miner will have to invest.
