What is the problem for an exchange to have their own token? instead it is good for both parties.
it is just like a member card for the user when we can get benefit from having one while in this case some exchanges are charging less fees for the holders.
and for the exchange themselves they can get fund to keep developing or maintaining their platform.
we have seen a lot of shitcoin created everyday, so it does not concern us at all as long as the exchange works as expected.
You can see that many exchange platforms are currently present on the crypto market. they are promoting not just their platform. but also related to their own tokens that can later be traded on an exchange.
there is nothing wrong. but it looks like a strategy to keep the exchange busy with new coin events.
like IEO on binance. which indeed requires IEO participants to have a BNB before being able to participate in IEO sales.
but I prefer exchanges that are up and running and recently releasing their own coins. they already have a market then make a sale of their own coins once their platform is up and running.
like NOMINEX which has just released their NMX coins which have been opened on several exchanges as well.
