If I correctly remember, then today HashFlare carries out a cloud-mining 4 cryptocurrencies: Litecoin, Bitcoin, Ethereum, Zcash. Initially, the mining was carried out using two algorithms - SHA-256 for Bitcoin and Scrypt extraction for Litecoin, but over time, the service added capacities and expanded the infrastructure for the mining of other crypto-currencies.
To start earning on cloud-based mining, you need to select a tariff and purchase a hash. You can reduce the total purchase price by applying the hashflare discount code 2018. A day after payment of the contract, the client receives the first payment of rewards.
What do you think about it? Many of my friends have earned so much for a long time, but I'm not sure. maybe someone has already used this technology?
