I think this is not the place to complain about binuses being too low...
Some casinos give higher bonuses, but that doesn't mean you can make money easier there. It all depends on games and house edge...
I believe the BetFury team are well aware that their bonuses are considered low and that there are other casinos that offer better bonuses than they do. But have you considered that maybe they don't want gamblers on their platform gambling recklessly with a target to meet the requirement for the bonuses?
or to discourage gamblers interested in bonuses alone from their platform?There must be reasons for the bonuses to have been kept that way.
