Stable prices could be due to very low trading volume because it means there is no activity on the BFG market, usually, we can check on coinmarketcap for trading information, and indeed BFG trading volume is very low if I'm not mistaken a few months ago it was still around $500,000 but right now it's only around $30,000, but I don't know if the decline was intermittent or just in this 2-week span, since you said price stability occurred in these 2 weeks.
My guess is that more people choose to save, stake, and earn interest. I don't really follow the development of this token, or the way that can be done to benefit from holding this token, because it only has a very small portion and is in this casino.
But do not rule out the possibility that the decreased trading volume is a global effect because the crypto market has been quite calm in recent times and will usually increase again when the Bitcoin market starts to move quickly, because traders will always use the Bitcoin market as a benchmark for their movements.
