It's ironic that one of the biggest scammers in our lifetime, is accusing BTC to be a fraud.
You could say that he knows a scam before anyone else see's one, but that's to be expected. People want to make money, one way or another.
No one if forcing anyone to invest in anything. Everyone encourages though that you be cautious, and avoid falling into the scam trap.
Crypto is about money, everyone needs the money. Ico just a part from various ways to spend your money to get back your amount with a decent profit. If you are want to blame the ico with the stock manipulator's statement such as jordan which already arrested for 22 months in prison and you are kidding me, dude.
