I also rarely take the bonuses and only take them if I think I can fill the requirement. Because I am not a person who spends too much money on gambling, I prefer to play directly without taking the bonuses. The requirements are too high for me and I don't know if I can reach it or not so that is why I don't take bonuses if I don't see it is interesting for me.
The thing that makes me difficult for me is wagering requirements because sometimes that is too high for my budget. But if there are free bonuses, I will take it because that is free

Well, it's the right approach not to take bonuses if you're not sure you can fulfill the wagering requirements.
As for bonuses, it's worth noting that betfury used to have a lot of free bonuses. In particular, it was possible to collect a large number of BFG tokens from free boxes.
