Can cryptocurrencies be liberated from the menace of exchanges? In my understanding the primary purpose of a cryptocurrency exchange is to let users trade traditional currency for some kind of crypto-coin. Most exchanges also allow provide storage and crypto-to-crypto trade.

But exchanges add centralization, they have questionable security and they can manipulate cryptocurrency prices at their will. 

Can there be an alternative market structure for cryptocurrency that liberates us from evil exchanges?
There are decentralized exchanges that will launch soon such as Bisq or Coinffeine.
