I have started to learn about blockchain technologies, BTC and other crypto-currencies and right now interested in mining. I know that mining of BTC is not very profitable right now, but other currencies can be profitable.
I looked at ETH, DASH and Monero and according to this site I can earn near 150K per day with AntMiner S7, which seems to be unrealistic.
Please help me understand how this stuff works, is it real or have I some misunderstood something?
