In my opinion, a good exchange should have a nice and friendly interface and quick accessibility. Good support, High trading volume, Low trading fees, instant deposit and withdraw that's it.
This forum can give you a lot of good choices to choose from, but you also need to be careful with these exchanges because it will certainly not be as safe as you think and if you have problems giving In that case, you should give negative ideas to make them better. Currently many new exchanges are in a way to attract investors and if it is an exchange that is trusted by people, you should consider using it because it will be very good for making a profit.
At this time there have been so many new exchanges that have sprung up, but even they have missed a number of important things that are really needed by users. If you want to make a good exchange then at least prioritize customer service that is ready at all times and also has good security and is easy to use.
We can't stop them, they will try to operate because of the potential in this market.
Binance which is the most popular exchange now are making huge money because their trading volume is so high, for sure new exchange's goal
is to maximize their income but it needs time to build reputation and people now are wiser, they will ensure they trade in a liquid and reputable exchange.
All exchanges are expected to earn big profits just like Binance and they are trying to be able to best develop their platform. I think in the future there will be great competition because people often tend to choose new exchanges with a better interface or want to find the best possible investment place. This will definitely make the market better and people have more options besides Binance
