Oh my G, can that be considered volume? That's a funny volume, maybe those who buy it are just gamblers, but if it were me, I wouldn't waste any cents on that coin to be honest. But it's listed on the exchange, so it wouldn't be surprising if it gets delisted a few days from now.
Given that the FUN token listing on the exchange was recent, I doubt that delisting due to low trading volumes will happen in the coming months. Probably Poloniex may remove the FUN token in half a year or even a year if there is no activity on the FUN/USDT pair during this time.
