BTC was somehow good as idea but the centralized exchanges are ruining the whole system.
All exchanges for every commodity traded on earth from equities to metals to public coins are centralized at the moment.
the BTC philosophy is based on other things, right? De-centralized services
The currency is decentralized. The exchanges are not.
I agree that decentralized exchanges will be a game changer, but they will only be possible using crypto-tokens and so will only be truly decentralized for exchanging already decentralized asset classes.
Look into atomic transaction protocols, that is how they will work. We are getting closer
