What's funny is that the Winklevoss twins challenged Jamie Dimon to short BTC if he truly feels that it's a fraud. It hasn't been done (more than likely due to speculation that it's) because Dimon probably doesn't truly feel that Bitcoin will fail.
what!! that sounds dumb.
they have been shorting bitcoin, why do you think he called bitcoin "fraud" in first place? they took their places and got ready for a big dump which he then caused. i wouldn't even be surprised to learn this was a coordinated scheme with some big players in the market.
and the actual funny part was when someone proved that their firm had bought bitcoin in that dip
