The wager requirements for free boxes would have been a good decision if Betfury had kept everything as it was. However, Betfury decided otherwise, and it seems that free boxes only for rank 2 users and above are a more optimal solution for them in the fight against abusers. Even if we assume that some abusers can reach rank 2, there will be only a few such abusers of their total number, which means they can easily be detected and blocked by Betfury.
Wagering requirements would indeed also be a good idea. Since the beginning, the boxes were able for level 1 but initially the rewards were a lot higher and more interesting. They kept dropping the amount you got collect but guess it didn't really help to weed out the abusers so there are now taking extra steps by making it only available for rank 2 and upwards.
as far as I know wagering requirements are a great way to get rid of bonus abuse in any casino and they are now used by all casinos that offer bonuses on their platform.
and sometimes if the wagering requirements are too easy to achieve, they are also vulnerable to abuse by irresponsible people and worsen the development of casinos.
so for me BetFury provides a bonus with wagering requirements, that's very easy to achieve if you really enjoy your game session.
