His best case scenario is opening a Wise multi-currency account, with supporting instant transfers free of charge in many cases.
Bitcoin is not accepted anywhere, practically speaking.
As such you're only looking at a small fraction of the transaction. You actually need to (1) transfer money into a crypto exchange for a 1-2% fee and whatever delay the domestic transfer takes (2) purchase Bitcoin for whatever fee the exchange charges (3) transfer it for $0.50-50 depending on the fee du jour (4) hope the market doesn't collapse out from under you while all this is happening (5) sell it at the destination unregulated exchange for whatever fee they charge and hope they don't flee with your money (6) transfer to the destination bank account, waiting as long as a domestic transfer takes.
This is probably a few days total, with severe counter-party risk, forex risk, and substantial transaction fees.
Or you can use Wise for a very low fee directly bank-to-bank, or open a Wise multi-currency account and support almost-free instant transactions. They're also super, duper regulated by a number of world regulators.
I know which I'd do, but to each their own.
