Once upon a time there was a lot of hype about this token and this casino site but now that hype is gone. BFG tokens were previously available for free when staking on this site and had a bounty campaign on this forum. And at that time not many casinosites were promoted in this forum which is why Betfurry dominated this forum. But now with lots of competitors, BFG has fallen far behind and is slowly losing popularity. And this is why the value and demand of BFG token is decreasing day by day
I think you got some things mixed up... BetFury had a signature campaign and those who participated were paid in BFG tokens, I don't recall any other casino doing anything like that. Mostly casino tokens are mined by playing, the more you wager, the more you get tokens, it's how things work with in-house tokens.
Maybe we can say that BFG has fallen, but some others have fallen a lot more... and some others made progress. But I will repeat once again, in-house tokens are just more feature that some casinos offer, the main point is in the casino and playing in that casino. It's different if you are just an investor and you invest in some casino in-house token and you expect returns from that investment. Some of us are real players, we don't care about the price of their in-house token.
