I would expect such price loss because the project got listed for free, it's a different story if the project conduct an IEO on binance, investors just will definitely take out profits, your advice ain't bad but it's pointing to free listed coins
Is a coin registered for free not good, bro? because registering a coin into the exchange, of course there is an agreement between the project and the exchange, if indeed the exchange gives relief to the coin to be registered for free it will not be a problem and it is fine to do.
