Not only people will buy more BFG if it is listed on centralized exchanges but it also helps the Betfury to gain more popularity as when people will buy this token, they will check its use case and therefore they may come to know about this gambling site. Yes, the gamblers are already aware of this site, but many traders who are using the centralized exchanges, when they do the fundamental analysis for those token for investment/trading, they will be known to this site and many may play and even stake at Betfury.
Anyways, if there is a budget constraint, then I could not say anything but if there is a budget with the team and they are not focusing on centralized exchanges listing, then they are doing it wrong.
I haven't read more about this project I'm sure they will list their tokens if eventually a bull market will come, that's why it's not strange that many new crypto projects have sprung up lately considering the upcoming bull market due to the Bitcoin halving, I think also BFG might as well will take the opportunity to get more profits, but again it all depends on how they set their project roadmap, because so far maybe they have remained consistent in their roadmap and maybe there is nothing in the roadmap regarding BFG registration to CEX, so just wait
