Anyway why should they really mine ? It is cheaper for them to just pay dust for months than real mining. They don't have to buy expensive hardware with a low lifetime, pay electricity, maintenance... No, a clever company just sell ghost hashrate because it is more profitable. Customers don't ask them to prove their hashrate and they satisfy dust payouts for months. Once contract closed they realise they lost 75% what they paid but during these months Genesis Mining spam for news contracts with lower fees, new coins (X11...).

Whatever they pretend they know they will earn at least half what you pay. There is nothing behind this company, just a web site, some pictures for noobs that's all.

What you pay is a login and a password in their database and the certainty they will keep 50% to 75% what you paid forever.

It is a very profitable business.

If you don't mind losing money (some people say they don't care), so give me your bitcoins and I promise to pay you back 90%. It is a good deal, because you will just lose 10%
