It is the weakness of the centralized exchanges! We got a hard lesson from the collapse. They can do everything they like for their own profit, like manipulating the price, identify leaking, getting hacked etc.
And if case you did not notice every other bitcoin service beside blockchain&bitcoin itself is not decentralized. Every bitcoin exchange so far, every bitcoin payment processors, online wallets, casinos.
Everything is susceptible to identity leaking, hacking etc. This means we are doomed?
