Some exchanges that have P2P first names have a problem which in my opinion will only pose a risk to the assets we have on the exchange.
I feel it because it looks like some projects that have been supported from the start and can instantly drop out of their exchanges and return. this is actually an unwise step when difficulties are left so that many become worthless tokens.
when there are many tokens that are no longer valuable, the exchange place should delete them, just like etherdelta, as there have been many junk tokens there at very cheap prices.
