Crypto as a competitor to SWIFT is kind of interesting though. SWIFT is basically a fast international transfer. Crypto is actually pretty great for that because you can do a fast transfer against domestic crypt/fiat pairs and after the int'l crypto transfer dump back into fiat so the currency risk is relatively low. Using SWIFT / int'l fiat transfer to buy crypto makes no sense.

In short cutting off SWIFT from crypto exchanges is a nothing burger because domestic crypto/fiat pairs are available and int'l transfer of crypto bypasses SWIFT.

Or you can do that all in a database without the wasted energy.
