Someone wise once said, if there is a way to profit from a thing, you can bet Wall Street will figure it out and execute it better than anyone. I simply cannot imagine a scenario where big money is idly watching from the sidelines as average joe's pocket millions in crypto.
Edit: By "average joe's" pocketing millions, I meant collectively--not any single individual, even though there are many who obviously made millions by themselves. And yes, "average joe" applies to the early investors in crypto from back in the 2009-2011 era. They were for the most part everyday people like you and me, not big bankers and high rollers (although there were a few of those, too).
