in my cloud mining contract they are giving me 3 times less than the real bitcoin mining.
in the photos up are explained your questions.
ive lost $200 on minergates cloud mining contracts and they never paid me.
in pool mining for altcoins they are giving half hashes to every client.
i mine with my cpu 20h/s on minergate xmr mining pool when with the same cpu in miningpoolhub again mining xmr im getting 45h/s.
they are big scam website and please dont trust them.
I LOST $200, NOTHING FOR MY ECONOMY BUT IF THEY STEAL FROM EVERYONE THEY WILL CONTROL A BIG AMOUNT OF BTC.
