At present there are numerous trading platform with good volume like Binance, Bitfinex, Kraken, KUcoin, Bittrex, etc and these are well know trading platform as well but can I get your help to identify a new trading platform with it's own token which might become a valuable token in the future just like BNB ? I want to experiment by investing into a exchange token when it's value is less as it might give a good amount profit. I am sure those who invested into BNB at it's early stage got my point.
I dont think that you need to be directing your research towards that area so that you will not end up into the arms of some of these scam exchanges that promises to have a token but when you buy the token, they will only end up being a pump and dump token without any volume on the exchange to keep its value high.
Binance that even have several products that should be making the value high is still struggling with their own token to rise more than what value it has not, not to talk of those unknown exchanges that you are looking for, because the reason why I called it unknown is because you have listed majority of the top and wonderful coin exchanges that we have so far, and anyone looking for exchanges that is better than this is really looking for what will destroy him or her.
