You can try using forkdelta decentralized exchange which is a fork of etherdelta exchange. Forkdelta exchange is faster in response but little bit different interface with respect to etherdelta. Also, you can give a try to IDEX decentralized exchange very easy to use with user-friendly interface. You can only trade ETH or ERC-20 token on these exchanges.
ForkDelta is quite fast compared to ETHDelta but being a fork of the original ETHDelta decentralized exchange, I'm afraid that it would suffer the same issues in order processing speeds over time as people begin to use it at a large scale. The IDEX exchange is quite new to me and doesn't have much liquidity AFAIK. But, if it's fast enough to handle my ETH to token trades, then it'll be quite worth it. I'm also looking to trade crypto-to-crypto, not only limited to ETH-to-tokens trades. Since decentralized exchanges are nearly beginning to emerge, I believe that it would take a couple of years from now before they become as popular as centralized exchanges.
It really depends what coins you're looking to trade. They all have limited markets, whether because they are ETH/ERC based, or because only so many coins have been listed by developers.
Theoretically, CryptoBridge is more robust than Bitshares exchanges because it uses a distributed network of gateways. In practice, its performance is pretty disappointing. I've used Forkdelta and Etherdelta to accumulate ERC-20 tokens but......meh. I've heard good things about the prospects for Radar Relay, but I can't say I'm familiar with it and I don't think there's much liquidity.
We're definitely still in the very early stages.
Yes. These are still the very early days of decentralized exchanges. However, I'm amazed how quick they've advanced in handling scalability issues, via the use of different blockchain networks that are much more scalable than Ethereum right now. I've tried CryptoBridge and it's quite fast, but it lacks liquidity just like most DEXs out there. Centralized exchanges are still in the lead I'm afraid, and until people realize that such services are highly manipulated by governments and their funds are at risk, they won't switch to a decentralized alternative anytime soon due to the high liquidity centralized exchanges provide.
In my case, I'm looking to trade Ethereum to tokens, as well as, any other cryptocurrency (like Bitcoin) to another cryptocurrency. Perhaps, with atomic swaps, things would be much easier, but until that happens, then it's up to DEXs to improve in scalability and liquidity for them to become extremely popular.
In the meantime, my choices for decentralized trading are Bitshares, CryptoBridge, and IDEX. Unless there's a better DEX out there with instant speeds, those would be my top choices for now. One DEX I'm looking forward to is EOSFinex. This one will live on the EOS blockchain, which would be superior to other DEXs simply because EOS is much more scalable than any other smart contract platform I know of.
