May be they know something. For example, acquiring BTC deposites and paying in USD is a good idea in the case of BTC/USD exchange rate this autumn will follow the last one, from current 500 up to 2500+ in December.
It must be that.
But it's not December. BTC will hit 3000 in Nov 12.
As in it must be a ponzi. If you meant that, you probably are not far from the truth.
We can't be sure btc will hit 3000 in november, for all we know it could plunge to $100 tomorrow, then cryptcominer would be holding alot of worthless btc and have to pay out ALOT more ($500 would be 5 btc instead of 1 btc!)
It's not what he meant.
And a btc plunge won't be the cause for the end of this thing.
