I read something about this back in early May Bitcoin is coming to hundreds of U.S. banks this year, says crypto custody firm NYDIG, but I also found a topic about it here. Also, all of this was preceded by news from last year Big decision by the OCC - Banks can now hodl Bitcoins.
How good or bad this is for BTC is hard to say at the moment, as the question arises as to whether people really want to invest in Bitcoin - and it should not be forgotten that the US has the largest crypto ATM network in the world and also the largest crypto exchange. Therefore, it is not a problem for them to invest, but the real problem is their tax system, which for most is a real nightmare (if we look at it from some other parts of the world).
