I don't think it's going to be that groundbreaking. Most people are used to how Binance works right now. It's extremely responsive, trades settle instantly, and spreads are extremely tight.
Another benefit is that they don't seem to care about KYC and all that nonsense. In other words, even if Binance's DEX will work better than all the other ones out there, people will still use Binance's main exchange.
I can't even blame people for that with how little of them actually care about decentralization. Most people just want to trade without headache and Binance allows them to do exactly that.
DEXs will only gain traction when the centralized ecosystem has become entirely infected with the KYC virus. In other words, only when there is no other viable option left people will go for DEXs.
Exactly. People won't care about decentralization, if they could easily exchange cryptocurrencies without downtime. Since centralized exchanges like Binance provide the most liquidity, buy and sell orders become settled quickly. In contrast, decentralized exchanges lack liquidity but they’re much more secure and cheaper in costs than their centralized counterparts. Eventually, people would switch to decentralized exchanges if they continue to experience undesired situations within centralized exchanges such as hacks or theft.
With a decentralized exchange, there's no counterparty risk, you're the sole owner of your funds (if you have access to your private key), and there’s no single point of failure. It could be said that decentralized exchanges would live almost forever if the blockchain they're operating within is still alive. As such, I believe that the best decentralized exchange yet would be Bitshares.
Bitshares is extremely fast, responsive, and has some level of liquidity. While centralized exchanges still have greater liquidity than the Bitshares DEX, this last one is the safest approach to trade your cryptocurrencies without having to worry about hacks or theft. However, not everyone is accustomed to using decentralized exchanges, due to their complexity in design. Therefore, centralized exchanges would still have the lead unless something very bad happens with them.
Nonetheless, the best decentralized exchanges I've found yet are: Bitshares, IDEX, and Bisq. There's a new one that will be launched soon called EOSFinex, which will live on the EOS blockchain. Once it's up and running, then it could become the best decentralized exchange in terms of speed, and lower costs. Just my thoughts
