But if an exchange goes through a hard period of time and shuts downs then ultimately that token will come to its end because there is no community other than that exchange supporting the token simply because it has no usage outside the exchange.
So true of your insight on this. I have a couple of Tidex tokens from the Tidex Exchange (it's an exchange token too) sometimes I get worried of what could likely happen to my hodling if things were to turn south for the exchange because Tidex is only listed on just that one exchange. But like BNB, good things of life don't come easy. They take time. I remember when BNB got listed on its own exchange and how it dragged around less than 30 cents for weeks before spiralling onto a bull run and hitting an ATH. I strongly believe that every exchange token is laudable and a good buy.
