Meh. The point of crypto is to bypass the present rails of commerce. Not to add yet another layer and middleman / middleware to the mix that adds fees and overhead.
It's my theory that crypto is following the same arc that Microsoft used to dominate personal computers and office software.
Paypal recently announced crypto integration. Other payment processors will follow. Eventually merchants will want to save 3% and accept crypto directly. They might even pass the savings to the user.
