The concept of a decentralised exchange is obviously good, and it takes away the counter party risk that traders have to deal with every time they deposit funds into an exchange. Especially in this day and age where KYC can be used as a legal reason to hold people's funds.
However, the integration of different coins and trading pairs over different platforms, especially in regards to the integration of fiat currency is still uncertain with decentralised exchanges.
Perhaps a protocol can be developed in the future that allows this to happen, but I think that people currently are still not fully comfortable with all aspects of a decentralised one yet. They instinctively still want support and fear that they won't get that with a decentralised system, and often the spreads on decentralised exchanges are just too high and there is a general lack of liquidity. I'd definitely be willing to use one in the future though, if these problems can be solved.
It is very early still and people are not ready for pure decentralization.
We hope that in the next years, with more and more education and different blockchain tools,
everyone will start using DApps seamlessly, like the way people started using internet applications.
