I started mining bitcoins on Genesis mining about a year ago.  This is a great way to make more BTC. 
I made my money back in just under 4 months,  and everything after that is profit.  My payouts get bigger the more BTC is rising in value. 
I very much recommend cloud mining.  Best part they pay out everyday.  I used a the mining calculator on cryptocompare.com to find out how much money I can make.
The contracts will sell out fast they always do.  Please use this code at the checkout and get 3% off your order.  hVIeOt

I also mine ETH, ETC, and ZEC  BTC is the best with the highest payouts.
This really is a great deal and a great investment.
