Sorry I didn't see your message until 10 days later. Did you know that the internet is worldwide? I do use an e-Transfer to transfer cash in Canada but more than likely, a transfer on the web will need to be done internationally. A stablecoin is a way to make sure the value is secured, at least as much as what it's backed on and the company holding it, for the duration of the transaction.

Any Canadian Exchange (and not a specific provider) could hold that stablecoin and many people will do arbitrage over it which will make sure I will be able to buy it easily for a minimum of fee.

That's specifically for me as a Canadian in a first world country too. A stablecoin allow that in ANY country, no need to do a case by case.

There isn't a single country in the world today where you can't spend a US dollar. Canadians will happily take them, especially at a 1:1 exchange rate.

I could see a decent amount of usage for dApp developers or anyone who wants micro transactions on their platform. That being said, “stablecoin” is probably quite useless outside of that very narrow use case.
