I received 100% bonus After depositing 5$ and free spins helps me to get a total 20$ Bonus .

But I think to redeem bonus 40x wager is way too much as a starter , keep it to 5/10x and an option to withdraw profit will likely great for user's. It's my opinion as a user's. It will keep hooked as a new user
Before deciding to activate the bonus, it is better to read the rules so that you can make the right decision, I am not interested in taking this bonus because of the 40x wager requirement, but if you check at other casinos it is a common value at the casino, even higher up to 60x.
Because at betfury the deposit bonus is not automatic so it takes a player to activate it so that the 40x wager should have been understood beforehand.
But it's not impossible for you to get through it, are you successful passed it?
