I've heard this and it would be big news. It's ironic with Jamie Dimon making negative statements about Bitcoin. However, any smart investor has to seriously consider cryptocurrencies or they are going to miss out on a huge opportunity. They've already missed the last eight years of huge gains and there's no denying that it's here for the long term.
But of course it is good news when large banks want to invest in Bitcoin. It will probably help drive the price up some and make Bitcoin less volatile.
