Yeah but its Poloniex, many are afraid to use that exchange after what happened during 2017. Basically they had to KYC people and they did it by locking accounts first. And peoples funds were trapped for years. And later it go sold to another company and then sold to I think Justin Tron and if I recall they don't require KYC now.
Either way, its not a big exchange like Binance and hence why the volume is so low. Most likely if it continues they might end up getting delisted all together. So the price of FUN doesnt really mean much since there is no trading volume.
Yup, I remember very well how Poloniex plummeted from the top exchange to the bottom. Actually, that's why the growth of the FUN token in June seemed very strange to me. The only thing that comes to mind is that someone manipulated the FUN price on purpose. And I don't rule out that it could be a trick by the Freebitcoin team.
