Fiat is dirty and with the recent events this has become apparent way too often.
Now with paypal finally saying they are accepting crypto to actually pay for things for millions of different merchants and not just be able to hold on to it in their paypal account's wallet (what would be the use of this?!),
they might be actually solidifying they are not confident in only accepting fiat currency on their platform.
They were are looking for another viable option and have found it in cryptocurrency instead.
