It is difficult to say definitively whether cryptocurrency will replace physical money and become the primary form of payment in everyday life. Cryptocurrency has seen tremendous growth in recent years, but it still faces a number of technological, regulatory, and legal hurdles that could prevent it from becoming a mainstream payment method there are still millions of people around the world who are unfamiliar with the technology behind cryptocurrencies, and who may not be willing to adopt it as a form of payment. Until these issues are addressed, it is unlikely that cryptocurrency will replace traditional forms of payment anytime soon
For cryptocurrency to replace fiat money, it requires, first of all, the willful decision of the government. It is worth considering that the government wants to always control everything, so you should not expect great freedom in the introduction of the state cryptocurrency. So I don't think there will ever be a full replacement.
