Stablecoin platform as a global 'bank' account for long duration travel?

[BRIAN.A.DAYES]

I'm new to the stablecoin arena, and interested in learning if a stablecoin account can be used as a defacto global bank account - readily accessible and able to withdraw USD from various countries. By way of example, as a Canadian, can I open a Canadian-domiciled Coinbase account (or other platform, like Bianance), buy USDC (I understand Tether (USDT) is not available in Canada), then access this platform/account globally to withdraw USD? I'm looking for a solution to avoid high standard banking/ATM fees, brutal f/x rates, long settlement times for wire transfers, and the risks of carrying large physical sums of USD. My experience is that I can get much better USD f/x dealing with local merchants when travelling. Thoughts? Experiences?
