379 TH/s gives 2$ ... I invested 92201 USD on bitcoin.com cloud mining and before one year paying me 2$ a day. I had also invest on minergate.com at the same time but for 18.49 TH/s they give me 10.77 USD. It means bitcoin .com should give me 220$ a day not 2$.
and also bitcoin.com stopped mining about 2 month for migrating from china to us. who will responsible for this loss
What should I have to do to get my money back ?
You shouldn't even trusted any of those cloud mining companies at the very first even they really pays you. Didn't you made any research or even understand first how those cloud mining works before putting that huge amount of money on it? People are talking about it everywhere right now that investing on this type of investment is not worth it. I'm not sure but I think you will not be able to get your money back, what you can do is wait, unfortunately you will have to wait years before you can break even with that $2 a day. And hope that this company will not turn into scam like what previous cloud mining company did.
