I understand their goal because BFG success is based on the casino performance. The team can use up all their tokens for now in marketing but they can easily save the price once they have steady profit on the casino that will be used for buy back. Patience is the key for this kind of investment.
If I'm not mistaken, the Betfury team has never published any marketing reports. So we only know that they initially allocated 10 % of the total BFG emission for marketing, but we don't know how exactly they use BFG tokens and how it affects the BFG price.
By the way, does anyone on the forum try to compete for the grand prize in the "Fury Games Legacy" event? It looks like there is strong competition since the user in 1st place has already wagered over 1 million.
