U are forgetting that there are still some problems. The price of Bitcoin goes up and down a lot, making it risky. It can also be slow and expensive to use sometimes because of the way it's built. Plus, many people don't understand Bitcoin and the rules around it aren't clear in many places.For Bitcoin to become really popular for sending money internationally, we need to solve these problems. This means making it easier to use, teaching people about it, and making the rules clearer. It won't happen overnight, but Bitcoin has the potential to change things for the better.
If we are talking about the use case we are discussing related to the topic - yep, Bitcoin won't be that, at least not without the full-scale adoption by both big and small institutions alike, plus lots of people around the globe (more than the amount we have now).
Before that, Bitcoin would just.. coexist as it is with the systems we have.
