Perhaps in the future people will have no choice and they will be forced to use cryptocurrency, or maybe there will be some alternatives. It is difficult to answer your question now. But the fact that the blockchain technology is already actively used is not a secret to anyone.
but if there is a technology coming in and that is better than crypto, crypto can be removed and people will use new technology, so in the future we don't know what will happen.
but I think Crypto is still the best for the next 5 to 10 years.
