I think Bitcoin will never replace currency.Bitcoin or other cryptocurrencies is a product of the oligarch - those who hold 90% of the world's total assets or we are known as the rothschild family. It is a tool for them to make money. We also cannot deny the power, superiority, breakthrough of Blockchain technology, about its benefits. I think that is the value of Bitcoin, not the value of money. Bitcoin or crypto was born to replace the current money system, bringing fairness and transparency to money and finance. But think about it, we live in a world where money is power. The more possessions you hold in your hand, the greater the power. If a country has monetary autonomy in its hands, it is a very powerful nation. So, how does Bitcoin or cryptocurrencies - things that provide decentralization (rather than centralization), transparency, and equity - can replace the current currency - which will bring power to itself covered. Therefore, I believe that in the future, cryptocurrencies are still just a tool to make money, not a substitute for money.
