Yeah it is good to use crypto for the transaction usage but it is not in short time to switch people into that method of leaving. Cause some of them are didn't know about crypto, they just know Fiat or other currency. We can not force them to switch cause people perspectives if they can hold and see their fiat an they felt that is an tangible for them.
It's just about the beliefs and thoughts of some people who don't know crypto, so they often think that state or fiat currency is real currency and they don't consider anything else as real. In fact, the number of crypto currency users continues to grow from various backgrounds and I think those who don't believe in this can also find out for themselves by looking through true and accurate news. Even though they have basically never used it even for transactional matters or the like.
And with more and more people learning and using crypto, it will make the popularity of crypto even more, and this will provide an opportunity for people to trust crypto so they can use it like using fiat. But if people still don't want to use crypto or at least know about it, that's up to them, and we can't force them.
And we can only invite people around us to try to get to know crypto. But if they want to open themselves to accept new things, perhaps it will be useful for all of them because now they have a new way to get a better life.
