JP Morgan Bank of America Ban the use of credit cards to buy Crypto currencyand even Ripple XRP?

This is why I think that JP Morgan, Bank of America and Chase are wrong about letting people use their banks or credit cards to purchase crypto currency. They wont even let you buy Ripple XRP which if they used would make their transactions faster and cost them less money. So why are they doing it? Greed my friend, its all about greed. they say it is to protect you from bitcoin... they say it is because criminals use bit coin. JP Morgan needs to grow up and stop the fear mongering...
