I bought around 0,05 BTC of hash power a few months ago in pool.bitcoin.com. That entitled me to 4THs for 2 years.
At the beginning it looked good, but now every revenue I get is used to pay the fees, so I get nothing. My current balance is 0,0043 BTC and not progressing.
I guess we all should keep away from cloud mining.
I remember one guy here had invested so much on bitcoin.com cloud mining, really huge amount (will link thread later if I find that). He can mine only cents while in reality he had to mine 50$ and more daily. This website is owned by Roger Ver, he and his website is bullshit, consider this in future and get rid of anything that he owns.
