No, it is not. I've lived in several countries/continents in the past decade. So did many friends. We used traditional banks and newer players like Transferwise. Using BTC or any other shitcoin would have been less practical, riskier and more expensive, when not downright illegal (some countries control and limit capital outflows).
Riskier only because of the lack of experience of the people involved, and the UX gaps still being filled in - cryptocurrency is a very early-stage success(?) story of what will be a 1,000+ year journey.
You sound like a high priest of Bitcoin lol... “1000+ year journey”
