I'd say they have some good returns if you hold alot of them. If you check the staking page, they have an earnings estimator which you simply input the number of tokens and the earnings are displayed in daily, monthly and yearly.
Farming-wise, most of my holdings are there before I move them to staking if the pools dry up. Mind you, you have to compound them manually so a little inconvenience.
I own and stake both as well. If you like to play with different cryptos, stake them. Else if you want to trade for profit or collect more BFGs for a quicker payout, farming.
I agree with you and iv4n. It is still interesting to hold BFG tokens to receive the daily dividends in the various coins. I have around 3700 BFG tokens and earn around 0.15 -0.18$/day which is not so bad. I also do the farming because the APY is still quite nice and you can do it all on Betfury itself. No need to move coins to Biswap or another exchange.
For passive profits, that amount is really not bad. You can earn it just by holding your tokens and accumulate dividends. If you are not planning to sell your tokens and you are happy with how the team manage to continue the business and developing the project, there are good amount of accumulated rewards that you will continue to enjoy while you still have your BFG assets.
