JP Morgan has filed for approximately 150 "BitCoin Alternative" patents. All have been rejected. So Dimon is full of it.
As to the sell off, it was short-term profit taking, which BTC was due for. And FUD, on the China news. Nothing goes up in a straight line. It had little or nothing to do with Dimon. He said the same about BTC when it was $400.
Telling JPM traders what to do with their own money and threatening their jobs, is akin to a telecom executive in the 1990's telling employees not to use the Internet. I wouldn't be surprised if a few JPM traders happily tender their resignations soon, if they weren't going to already. Many will take their Christmas bonus' and buy BTC/crypto, as will many developers... and when more devs start migrating to crypto, the game will have really changed.
Price is climbing back up today. HODL.
