Doesn’t make sense. Why would anyone wire your bank account money to a crypto exchange, convert it to crypto, transfer the crypto to a different bank in another country, then withdraw it when they could just wire the money directly to the other country’s bank?

If you can’t wire money out of your bank account to somewhere else, you probably can’t exchange it for crypto either.
