Rise and fall
If these guys declare revenue, then I presume that they will have to pay taxes, what happens should they make a declaration when bitcoin is worth $4000, receive their tax bill, then bitcoin drops down to £200 dollars just before they make their payment?
Due to the volatile nature of Bitcoins, I would consider it an extremely risky means by which to get paid or make any kind os declaration.
Would it not be safer to wait until some stability can be ensured ?
Like the Stock market some people will make money with bitcoins but the majority will end up losing.
