Hahahahaa, JP Morgan (Jaime Dimon) is so anti bitcoin from the beginning they have to continue down the road of denial. What they say about crypto is completely meaningless, in fact what ever they say will happen id bet on the opposite happening. They just pissy cause they are missing the boat.
When Jamie Dimon called Bitcoin a "fraud" in September 2017, the exchange rate was going at $3,500 per coin. Now the price is around 1,400% higher (eventually he realized his mistake and admitted that he regretted about his statement in 2018). JP Morgan in 2019 came up with their "JPM Coin" to replace Bitcoin, but it failed miserably. So obviously they are not feeling very happy right now with the continuing Bitcoin rally.
