I mean to some are good in few things but lags in many things as a trader and developer. If you are a developer and you expect some features which are essential for making you pleasing and convenient while exchanging your cryptos then definitely you keep on comparing and must be keep on moving. This is what exactly happening to me.
All the websites we know of right now, all the designs, all the features, basically everything you have seen could be improved. Even binance, with the amount of money they have with the profits they are making, could afford to hire the best of the best developers and designers and creative thinkers to make the website a lot better, they can even afford it, may take a lot of time but could afford it anyway. So, to think that a new player may one day see how much profit these places make and can get in with billions of dollars in investment to build one and then start and takeover the market sounds possible to me.
