In 5 years from now, I think Cardano will be quite popular around the world. Possibly rivaling bitcoin and ethereum or even surpassing them.

If Cardano can solve the "volatility issue" that plagues all cryptos, then it could very will revolutionize the entire world.

Unfortunately, the token "ADA" would have to be reformed with some new rules to solve the volatility issue as it's value would need to be pegged to events in Earth's reality.

The only other way around the volatility issue I can see is the end of capitalism... but I don't think that is happening this century.
