Should it will prove that JP Morgan people taking part in trading crypto as mr. Dimon has made that notorious comments, a big stink could happen. A lot of question would arise concerning this matter in a case of big short in american banking.
Some good comments on Dimon's speech here

Also, Bitcoin is targeting those 10 trillions on BVI, Panama and the likes.. guess JP has some interests there as well
