Listing on huge exchanges such as bybit or binance requires big amount of money. Being listed on poloniex is still a good news meaning that the team is still active in the development of their token. It's good time to accumulate some of it now while it's not listed yet. Imagine the pump that would happen if it gets listed on big exchanges and gain more traction among traders.
FUN token was already listed on Binance long time ago until now. FUN is one of the few casino token that manage to be listed on Binance since they rarely accept casino token for listing due to strict requirements.
I think any exchange listing is indeed will give a boost on the token especially if the holders hype the token using the new listing.
This token received hype few months ago due to revamp on their roadmap so it’s price is sensitive to any news.
