Investors always seek for the platforms performance before pouring some money on their tokens created this is why Betfury needs to perform well and offer more unique utilities to their tokens which didn't been offered yet by their competitors. Also they need to conduct more promotion with extended efforts on other marketing stuff since for sure they will get the best result out of it.
New unique features and utilities are a good thing for any project because it almost always has a positive effect on the price of the token. However, in the case of BFG, it seems that the Betfury team has run out of ideas about the further development of the BFG token. At least I can't explain in any other way their decision to stretch the BFG mining for 53 months.
But what else can he do while the whole market is going through a lot of decision and uncertainty, you are right that they ran out of ideas, he has to make things more attractive, I think they can do a lot if they offer BFG with Airdrops and doing tasks, it is more attractive , or that they can make contests through social networks, mining here is not so attractive, players need more incentives to buy tokens and that cryptocurrency investors themselves are interested, mining is the best way out they have for now.
I agree with your opinion, if the token is continuously used only for marketing it will make the token price quite weak, so they should make an interesting idea for investors this will make the BFG token more stable
