If you ask me, it's not the fact that he believes that it's fraud, or a scan, or a bubble. He's scared shitless when it comes to Bitcoin. The fact that almost everything he's learned over his lifetime is changing with bitcoin bending economic concepts, He doesn't have that power he used to have. The fact that he is firing and threatening a divorce means that it's gotten to his head. It's just not rational.
I believe this is just a strategy to buy cheap bitcoins. Right after the announcement and Dimon himself saying he will fire anyone under him trading with bitcoin then the information about them buying hundreds of thousands of dollars bitcoins during the fall. A manipulation to its finest
. ah another attempt to suppress bitcoin's price so they can buy it up.
True, if they are honest to themselves, they can just reject the request of their client to buy bitcoin and advice them to buy other investment, instead of fulfilling the request to of their client to buy hundred thousands worth of Bitcoin. Well that is if it is really their client buying bitcoins.
