One idea!
I think they dont mine with hardware they collect the Bitcoins and make speculation on the bitcoin markets. Maybe with good bots and they have earnings much more as 40% in one month. In this case they can pay over years good earnings and make by themselves good earnings.
Some people earn their money at forex. This people make it with bitcoins. If they are good or have good bots they can do a long time but not for ever that is clear.
Yeah, but that's not quite the point is it?
For that total guess to hold water, it means they are also big time liars with all the nonsense about being 'cloudmining' a total fabrication.
I don't know about you, but I don't fancy giving money to some anon in the internet who is telling complete fiction.
Re: Forex trading and making loadsa mone, there's an much quoted stat in the biz called
90/90/90 which stands for 90% of traders lose 90% of their money in the first 90 days.
The idea that you plug in a bot and watch the profits roll in is laughable, nearly as laughable as someone paying 50% a month interest on their stake money.
Fail.
