here is a post from a guy from cryptocompare who is talking about another Decentralized exchange system:
https://www.cryptocompare.com/exchanges/cryptsy/overviewI think from these events as MtGox and Cryptsy should stay and experience that if we are dealing with new decentralized forms of money and contracts, we have to avoid the dilemma of delivering our goods to third parties to trades. We are saying that the exchanges should also work in the same way, decentralized, assets and operations log of its own chain of blocks. xD
They have heard or heard of Openledger?
What is OpenLedger ?
Its a fully decentralized exchange using protocols of BitShares an Graphene. OpenLedger allows you to convert bitcoin to fiat-pegged SmartCoins instantly or by limit order. SmartCoins can be withdrawn directly to cash via NanoCard, PayPal, Ripple gateway or money transfer. Speaking shortly this is what everybody was waiting for – fully decentralized, multi signature with options of easy converts to cash and even Paypal to BTC or Bitcoin to Paypal. You can trade there currencies, gold, oil, cryptocurrencies and many more.
I think there is not much need to explain while DEX (Decentralised Exchanges) are decent so this part i will live like this. (HINT – look at what happened to Cryptsy, MtGox and so on).
