All my friends have used Nicehash for years, made a decent bit of money with it. Obviously people think they are going to "get rich quick" which is not the case. You will get paid what you put into it. If you just have one machine, you will not make much. Friends usually have at least 7 ASIC Antminers or video cards to at least make it worth doing (income varies from about $250 to $150 USD each month or $2,500.00 a year from one S9 Antminer and 2 GTX 1080 and a RTX2080 Super). It's a fun hobby!!
