Bitcoin, Litecoin, Ethereum crypto mining at home is actually very easy. One simple needs to
(1) register with a reputable clound mining group such as minergate.com and
(2) purchase mining power called 'Hashrate' of HW.
We suggest at least 5000 H/s for Bitcoin and a few 100H/s for other altcoins like Litecoin, Ethereum, Dash and the other top Ten.
Beware that there are pyramid schemes and frauds masquerading as providing cloud mining services. It is best to use a well-established company that has a large footprint in the industry such as minergate. We will provide reviews of additional bitcoin cloud mining websites once we have had time to extensively test.
