Great! Here comes a bold prediction:
In the next 10 to 15 years, we will probably see a country launch a fully decentralized sovereign cryptocurrency.
That is, a government creating its own "official bitcoin", without control from a central bank — unlike the controlled digital currencies that some countries are already testing (like China's digital yuan or Brazil's Drex).
This idea seems radical today, but some small or innovative governments (like El Salvador or emerging countries) may adopt a decentralized model to attract global investments, digital tourists, and new economies.
