I don't think that will be happening any time soon because FUN token has already attracted negative attention.
As already mentioned above, FUN token was also listed on Binance and while it did gain traction back when it was listed on it, there won't be any significant surge in price now even if it gets listed on any other big exchange.
So there's no point of buying FUN tokens now since many people already know that it is a sinking ship and nobody would want to risk losing their money espeically when altcoins are not performing that good this year.
Well, take a look at the FUN token chart over the last few weeks. There has been a significant jump in price there. The price actually increased more than three times in such a short period of time, i.e., after the listing on Poloniex. This is quite strange and even suspicious because such activity is quite untypical for the FUN token.
I wouldn't rule out that the Freebitcoin team is manipulating the price, or someone else.
By the way, not every token shows such a pump after listing on Binance.
