Last year, JPMorgan’s Chairman & CEO Jamie Dimon called Bitcoin (BTC) a “fraud” and claimed that he would fire any employee trading BTC on the company's accounts. Dimon soon reversed his position in January, admitting that he regretted his earlier statements and adopting a lukewarm stance toward crypto. Dimon said he is, “not interested that much in [crypto] at all.”
Calling it fraud is one of the reasons why bitcoin's price crash last year but it is pretty obvious it is just their strategy because it was traced that after bitcoin's price is cheaper, JP Morgan bought bitcoin and it is quite ironic when Dimon said about being not that interested in crypto at all because he is actively trading it. Besides that, it doesn't seem that they aren't interested in crypto because they even assign a position for someone dedicated for cryptocurrency. Later on, we would expect banks to engage in cryptocurrencies as they can't just deny the fact that more people are using it every day. They should go with the flow instead of being against it since they can benefit as well to its technology.
Strategy or not but these influential people do have their own things on mind, they might oppose but behind it they are accumulating cheaper coins.
Banks can seriously affect worldwide propagation of crypto if they simply support wallets and transactions for top coins.
And direct crypto exchange to plastic cards will completely revolutionize the banking system.
