After much research, I believe that Genesis is legitimate. so I decided to invest $ 300.00 in it. Before did some calculations to find out how I could win,
https://alloscomp.com/bitcoin/calculator used the calculator to create an average of how much gain. today got the first payment. The amount was slightly below the calculations made, but it was to be expected since the mining began in the middle of the day. Now I will wait to see the performance and see if compença invest more. I think I'll invest with caution in order not to have any damage, after all, mine in the cloud is very risky.
Thanks to all for the tips. You are awesome =)
