Yeah, that's how it always works. You need to keep playing to win more BFG tokens so your dividend stays the same or increases. Luckily the number of BFG tokens that can be mined is capped, but for the moment only 50% of the tokens is already mined.
52% has been mined to be precise, and if i may add, 51% of those total mined tokens have been burned also. Burning rate seems to be rather effective imho. Funny enough, most of the BFG burnings happen when people gamble with it. Greed seems to be a good for burning and i can't see it ending even if BFG pays more, because it's just that greed what makes people want it more so they are willing to gamble with it.
If you bet on people being greedy, you will always win there is no doubt about that. That is what betfury did, they have built something that would be more and more valuable depending on how greedy people are and it looks like people are quite greedy and that wasn't a secret, we all know that humanity is way too greedy and betfury capitalized on that.
I believe BFT will get more valuable, obviously over course of some period there will be a moment when greedy people will realize holding their BFG will be more profitable and then a switch will be turned on and that will cause a lot of people to end up stop gambling and start investing and that is when BFG will worth a ton and that is when an exchange listing should happen because people will want to buy instead of earn BFG. No idea when that may happen but I do believe that it will happen for sure.
