i think that this is very good opportunity for billionaires to,invest in it.because i think that it is alternate of bank for then and i also want to ask you that it is better than bank because it gives profit at very high.and i also want to ask that there are still billionaires who manage to invest with bitcoins but there are businessman who are already billionaire that too busy in their own life managing those business they don't have such time to waste to use bitcoin because in their own business they can get what they can't get from bitcoin the best there is probably those billionaires who are holders of bitcoins is really great at gambling too.
