Decentralized exchanges should ultimately become the norm in cryptocurrency trading. It does not require kyc, is not centralized, your funds can’t be controlled by the exchange and probably a lot harder for hackers to steal and governments can’t regulate it. Having said that why has dex exchanges not overtaken centralized exchanges like bittrex or poloniex yet? What are the issues that is limiting growth. Also who are the main contenders in this field, which exchange will be the first to overtake centralized exchanges. I am thinking of investing in decentralized exchanges but can’t decide which one will be the best to invest in.

1. Kybernetwork
2. 0x
3. Etherdelta ico
4.NVO
5.flypme
6.airswap

Are they any other decentralized exchanges , most of these are only for ERC 20 tokens, is there a decentralized exchange that offers all blockchain based plus dag based coins , with high liquidity and ease of use.
Basically I am looking for a decentralized exchange that has the same user friendliness and variety and volume of bittrex and binance.

Please share your views and recommendations for decentralized exchange.
