using blockchain, people can limit what information others can access too, and you can also keep your own information. That's why blockchain is so important in the era of AI and facial recognition etc.

btw, many crypto enthusiasts love crypto currency because they are not controlled by gov, they are decentralized. But to be honest, I think that is pure BS. As much as people hate big brothers, people need big brothers. Just look at the drop in price of crypto currency any time there is news about gov try to regulating crypto. If it isn't depended on gov, why the drop?
