My Schwab account does international wires settled in USD or in a number of foreign currencies for free. (The official fee is $15 but it’s always been refunded for me.)
As the other @garmaine mentions, the currency conversion is at mid-market rates, no fees. I've compared the rates to Wise and other options and it's far less cost, and certainly less cost than the median tx fee of BTC by itself, let alone slippage or fiat conversions or exchange fees. Anyone who thinks BTC has any advantage as a medium of exchange I'm convinced has never actually used it/compared it to existing options.
Schwab forex exchange really is without fees. It’s done at the current forex rate with no basis points taken. I’ve checked my transfers against the forex rate for the day.
Schwab operates these retail banking services as a loss-leader for their investment products.
I've never experienced a bank that hasn't silently gouged on forex, and this is the first I've even heard of one that didn't.
Definitely good to continue to be vigilant about such claims.
As for BTC, I wouldn't use it for anything other than a store of value - there are far better crypto options for transferring value. Some cost fractions of cent and take seconds.
Others cost single-digit dollars, but are fiat-pegged so there's no volatility risk at all.
I didn't do wires with Schwab but I'll trust it's cheaper than your average bank when it comes to conversion rates. (They do refund ATM withdrawal fees for international ATMs)
