He probably meant
BFG farming, which was previously available on the Betfury site, and it should be noted that this feature was in demand among some users. Unfortunately, the Betfury team decided to finish this farming in the middle of last year, and now as you already said, farming on Biswap is the only alternative to this if we don't take into account BFG staking directly on the Betfury site.
Betfury removed this farm feature as requested by most of the token holder to reduced the number of tokens being emitted on farming that flood the supply. The old farming format is better because it rewards multiple token on a single stake token unlike Biswap staking feature that rewards single token.
I’m not in favor on removing that built in farm inside the casino because it distributes the casino profit directly to the user while the team is still just supplying liquidity on Biswap pool. BFG holders that wish for its removal just make their staking option limited since the circulating supply is still in huge quantity without this farms.
