So why bitcoin as future money?
Alternative to fiat
Decentralized design
Built with open source codes
Gives privacy to those that want privacy
Limited supply
Appreciative over only time period, a source of wealth for holders
But, yet, bitcoin is not the only future money, being an alternative makes it better, the reason we can even compare it with other currencies.
I am not saying that centralized currency should be remove instead I am trying to emphasize the freedom of an individual to use whether bitcoin (decentralized currency) or stable currency (centralized currency like dollar).
You are right. But many people are now leaving their Bitcoin on centralized exchanges which are subjected to central control, depriving centralized service users of the freedom. Many people nowadays do not know what private key is even all about because all they are using is centralized services. But the fact still remain not you key not your coin.
