I don't see this happening to be honest. Centralized exchanges are slowly losing against DEXes, so I don't see how PayPal would do any better. If anything, they're doing much worse than the currently existing platforms by not letting their users withdraw funds to their personal wallets.

And I realize that a lot of people are excited about this, but I just don't see why. Skrill has done the exact same thing some months ago, and no one turned this into a big deal so PayPal should be no different.
