It doesn't matter whether they were hacked by NSA, KGB, Chinese government, or other malicious scum. We need decentralized P2P exchanges either way.
This really sounds awesome but is too hard to implement
Easy to read but very difficult to implement. An exchange can say that they are decentralized, but it can't just happen. There should be some regulations made within an exchange and surely, a central authority should control it in order to make the regulations within the exchange happen. The markets are a free entity in the economy, but the exchanges aren't.
There have been many tried in the past , like darkwallet and all but i don't see a true Decentralized P2P exchange
