would you recommend a cloud mining company?
No!
see that there are cases of many people who have invested in cloud mining sites and have not made a profit
I decided to try after talking with several people who have been investing in bitcoins for years.
Everyone assured me that it's rentable it and i should invest more than $ 1000 to make it profitable.
I've tried it ... and I can assure you that everyone who recommends it is sure to benefit from it ...
It's nothing profitable

It is more profitable to invest buying bitcoins and wait for the price to grow ... or even more ... small coins like VERGE, Cardano, Iota ...
From my experience ... do not invest in cloud mining
everyone will tell you tat you will get back your investment in 3 months .... it's lie 
I hope that this information will serve all those who were doubting like me

7.5 TH / s should be profitable .... !! but the results are not as expected!
