BFG trading volume on coingecko isn't correct because this site doesn't provide information from other exchanges such as apeswap and biswap. By the way, if you check the Betfury page on coinmarketcap, you will see that the trading volume is ~$132k at the moment.
Yes, there are differences in the amount of trading volume between CMC and COinGecko.
We can see in CMC, the volume is good enough, as you said. And I think that we can consider the CMC data, moreover, Betfury has officially announced its listing in Biswap also as the data in CMC.
https://coinmarketcap.com/currencies/betfury/However right now, the price dropped very drastically, hopefully, it can be higher and higher again.
Unfortunately it probably won't be higher and higher for a while longer. The fact is that people bought betfury for a reason, but now that the reason nearly gone, they are only buying it for farming and you can do that with nearly any token at all, hence it doesn't worth anything valuable anymore, which is why it keeps dropping.
I believe that it has the potential to worth a lot in the future if betfury keeps improving, because they are tied together but that doesn't mean that it will happen, it just means that there is a chance for that. Hopefully they can realize that potential is there and try to reach to that but so far they have fall short, hence why the price is low.
