For some reason I just imagine Bill Gates buying into bitcoin before saying that comment, and then dumping all of his BTC at around $20,000 USD.
It's a funny thought for sure, Bill Gates, a PnD'er?
it is a funny thought because people like Bill Gates don't need the money that such actions can give them. they make that money so much easier with so much less risk in a short time. they don't need to do it with the high risk bitcoin.
and when you remove the monetary goals then you have a free mind to see only the real potential of the technology that bitcoin has. the power of decentralization that bitcoin introduced to us in form of a digital currency which is gaining more support every day.
