Dimon did add on Friday that he believed the blockchain technology behind bitcoin was valid, but he does not understand the value of "non-fiat" digital coins, that is, digital currencies that are not backed by a government.
I believe this says it all. That is just what keeps paining him after the whole manipulation, controlling and greedy stunts they have always pulled with fiats. He is confused, scared and does not even know what he is saying. Or he absolutely did know but just trying to play a punkish move to stare the market in his favour. He really should just shut up already.
