Still, I feel with 40-50x waggering are still bigs.
The chance losing are still higher. I once got these promotion with over 40-50x waggering and cannot passed these even already patience grinding for the waggering and just reached around 70-75% progress.
If they think based on the edge, perhaps maybe a little bit test based on the real situation.
40 - 50x wagger requirement on any bonus or whatever is simply crazy, it's absolutely too high if you ask me, and like you said, coming out with profit with such a wager requirement is pretty much very difficult..
A couple of times I've tried chasing after a bonus, the highest I've got I think was 30x, and still I could not meet up, I managed to chase till around 62% complete, I simply gave up because I had already spent more time and money than what I initially hoped for, even the games became very boring for me to play because winnings weren't fortcoming.
I simply avoid bonuses that come with any thing above 10-20x wager requirement.
