Wall street is such a financial institution that would be able to support BTC and include the item more genuinely into their own transaction procedures. But the question remains of the access of common people to access that or not.
Defi has already included that and in blockchain mechanism it fitted too well. But when it comes to an influential Institute as big as the market, then propagation of crypto into people's life would be more rapid and usual.
This might also be an exemplary set up for others to follow as well.
