BTC (actually Ethereum) are incredibly handy when doing international transactions. That these things are effectively global also makes them very useful, because of bank fees and the difficulty. At one point I actually sat down with a bank consultant to "design" a way to move money between (sets of) bank accounts in 2 countries just so we can do business. Still takes 4+ days (non-bank holidays) to actually happen. Ethereum can certainly match that and with much less costs.
