There so many good exchanges in crypto which traders can trade on and investors can also buy coins from them too, but I think it all depends on it's user interface because people will always go for what is very easy and comfortable for them to use, for me I prefer Binance, FTX, coinbase and kucoin.
Here I agree with you. First of all, we should be comfortable on the stock exchange. And everyone has their own ideas about what kind of functionality the exchange should have. I was initially impressed by the Binance exchange. I've been trading there for almost three years now. But if necessary, I use different exchanges to sell tokens.
