Hello to all the Bitcointalkers!
Because it is my first post, I have, at least, to present myself in several words. I am a coins/tokens dev and web developer full stack.
After several years of crypto experience, I decided to create my own project. It is not a coin, nor a token (there is already plenty of ERC20 tokens and coins), it is a cryptocurrency exchange.
There is already some exchanges available on the web, but I would like to build one which may fit to Bitcointalk users, it's why I opened this thread, and ask you today what do you like the most in crypto exchanges, as well as the things that you dislike. It can be specific features, themes, properties...
I want to build a good exchange, and for that I need to know your preferences.
Waiting for your replies

Before answering your question, let me tell you first that current exchanges in the cryptocurrency industry is around approximately more than 33,000 while alternative coins are around 7,800, these are just listed on coinmarketcap. In that 33,000+ exchanges, only few stands up and is currently dominating the cryptomarket in terms of volume. That is the 1st (first) key for an great exchange volume. Volume entails liquidity, which means anyone at anytime can buy or sell his/ her bitcoin or alternative coin (based on the coin though).
Second one that people consider are security of these exchanges. Majority of whats in the internet can be penetrate with all the hackers in the internet, it means, anything can happen. So the good thing to do is to ensure your clients, the traders, that there money in your exchange is safe. You can also offer insurance like binance, they have #SAFU, they have % of their profits locked to be a fund in case anything happens. There are still a of things to be considered, so be mindful in creating an exchange before spending a lot. Cheers!
These are a lot of exchanges and thats why you need to understand that you will need a lot of effort, product development, marketing, etc to stay in this industry.
