It happen because it didn't get much volume and attention, so even if bitcoin halving occur there's nothing happen on this token so its really up for new investor if they can able to handle waiting for the updates release by devs about this token. Many discuss about its possible exchange on other big exchange but it didn't happen. Maybe they are only focusing to bring good developments on their casino but doesn't have any concrete plan on how they can create demands on their native token.
It's worth noting that BFG has the most trading volume on Biswap, and it seems to me the Betfury team is more than happy with it. By the way, BFG was added to a few centralized exchanges earlier, but it turned out to be pointless since the BFG token is not in any demand on these exchanges. As for the listing on large centralized exchanges, I think there are only two options: either the exchanges themselves take the initiative and add a popular token for free, or developers should have enough money to pay for an expensive listing. Obviously, neither of these options applies to Betfury at the moment.
Not applied yet unless there's something that will push those centralize exchange to add BFG from their list, something that only happens when there are lots of investors and traders who use the asset for their investment which I believe that we both know that BFG is not on that state yet, more on staking rewards and how the casino will perform.
A speculative in terms of market values, something that traders and investors are not really a big fan, unless they see something from the project that really earned their support.
