They never really said it directly, but if you look at their old posts, you can see that they wrote that their goal is to reach the top 100. This way, they gave false hopes to their users because reaching the top 100 implies constant work on improving the token and, as a result, increasing the capitalization of the BFG token many times. Of course, now we can say that there is stagnation of BFG token development, and as you said, it has become a thing that the Betfury team pays attention to only in its spare time, although I am more than sure that it wasn't initially so.
It would be giving false hopes if they would abandon casino, token and would run away. So far they are present. I remember their goal, but it aint easy to get into top100 without huge investments in promotion and etc. Of course if will take time to achieve that. But, as BFG token isnt their primary goal, I dont see a problem here. We also have goals to become rich and famous. So far everyone one of us are on a long path to it. But it does not mean that we have stopped or failed. So do they.
Being at top 100 needs a lot of work plus huge support from their investors so maybe this might not gonna happen to them any time soon. But if they can make some good progress to their token well maybe this might be a game changer to them. For now holders should stretch up more their patience since we don't know their team is working around in the background and thinking planning about good to their token.
This will be a long waiting game so let see who are those people can able to wait for upcoming updates made by devs and if they can really earn something good for waiting for so long on BFG.
