That is true and I agree with you. Exchange tokens are some tokens which shouldn't be overlooked because of what they goes with, that is, in as much as the exchange in question is a good exchange whose team are really ready to move it to the next level, then buying and holding it, will be a good idea. At the same time, it is very good to know what not all exchange tokens are meant to be held for long term, that is, there are exchanges which lacks what it takes to last long term and through holding such tokens, the user will only end up wasting his time and money. So in all ramifications, holding a good exchange token is very good and a good idea as well, Binance and Kucoin coins are good examples.
