Can confirm most of what you tell here since I've done the same trip.
And especially cloud mining, stay away!!
I invested in "Genesis Mining" ..500 USD to mine Zcash, and 500 USD to mine Dash.
The Zcash gives back about 40 cent a day.. 40 CENT!!
I will be happy if i get the investment back within the 2 year contract.
Dash gave about 1 $ a day to start with, but when Dash start to rally.. They instantly lower my daily earnings.
So.. I will hopefully get my money back on the Dash. But no way i will get it back on Zcash.
And more.. They sell hash power.. i.e any loss in price movement, loss in any other way is YOUR problem.
I would call all these cloud miners SCAMMERS!
