I can't imagine how much money we would spend if the casino required x40 wagering requirements. But perhaps it's still worth trying for other people because of the possibility of taking the bonus from the free spins.
But if we don't intend to take any bonuses, we can try playing on that site. Oh yes, @OP, are there any other conditions when we don't take any bonuses from your casino? For example, we deposit $15 and just play normally but suddenly, we can win $50. Can we withdraw it directly or are there other requirements?
The x40 requirement is indeed very heavy for some gamblers to be able to take this bonus.
But for gamblers who have a strategy to bet to reach the specified conditions, they still reach these limits.
I think when you ask about not taking the bonus getting some winnings, it is very difficult and there is nothing a casino would want to lose by not taking the bonus but being given a few dollars in exchange for the bonus.
It's also possible that if the casino gave out a few dollars in exchange for not taking the bonus there would certainly be a lot of abuse of such a promotion which is very easy to achieve.
