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.
According to me exchanges should promote the usage of their coins/tokens outside the exchange to build a community in support of it. If your community consists of huge individual entities who believe you then a great community can be formed. Otherwise lack of applications would lead these things to disaster.
Binance has shown how it can work with BNB. of course, this has directly made all other exchanges
nervous and sensitive. for this reason, everyone wants to be here and get their piece of the cake.
just like the ICO wave started some time ago. that's what has happened recently with the exchange tokens.
