As someone who runs a business that has (small) offices both in EU and North America, let me share a quick overview of the current state of things.
When you want to transfer a non-trivial amount of money between 2 countries, you have likely received it in the originating country's currency and are planning to spend it in the destination currency. Now because you don't want to pay ~3% currency exchange fees to your bank, the only reasonable way to do this is to get an account with a business forex broker, that will offer you a rate in the ballpark of 0.5% off the spot price. You will have to do the KYC/AML [0], but the complexity of the whole transfer is basically this:
1. Do a domestic wire to your broker's office in the originating economic zone.
2. Wait for them to call you and confirm the exchange rate.
3. Receive a domestic wire from the broker's office in the destination economic zone.
You often need to show the invoices/contracts showing the origin of the funds and the purpose of the transfer, but if you are running a legitimate business that pays taxes, you will need those for accounting reasons anyway.
Now the 0.5% fee charged by the forex trader (that is bound to a bunch of rules and regulations making it harder for it to run away with your funds) is not worth putting your trust into a fully automated distributed ledger, where a lost password or a hacked computer could permanently eat away your money without any legal recourse.
So the only potential audience of a new international coin would be people actively trying to evade KYC/AML and that's exactly why the governments will do their best to prevent it from getting adoption (which is very easy since you can outright ban the fiat endpoints in your jurisdiction).
On the other end, there's a bunch of people who have never written a response to an AML inquiry and have hardly done any business outside of their own state, that are hoping to get rich quick by grabbing a stake at something they haven't fully researched and later reselling it at a profit to someone who will actually need it. I wouldn't see any reason for it to be successful long-term, sorry.
