Personally, I think projects like "SUSHI" don't have real use cases and real utilities. Traders only buy because of hype and instant profit, after the market collapse there are no fundamentals that are able to sustain the price which eventually drops like hell.
99% of all altcoins don't have any utilities and use cases. It's time to wake up.
On one hand I feel like it's not the exchange's fault that the coin team pulled an exit scam. Sometimes you strike a deal with a company and they bail on you. People are different some can be trusted and some can't.
On the other hand they should put more effort into screening these tokens or they'll become another shitcoin exchange like yobit.
