I don't know what you mean that farming wouldn't be possible, as it looks like biswap has USDT-BFG farm currently with apy of 60.75%. Is that something you were looking at or some other kind of staking?
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 at the end 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.
