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 money will depend on your capacity. We are not forced to deposit big here but sometimes a casino has a minimum deposit amount which you will need to match if you want to avail the deposit bonus. The smaller the amount the easier for it to be accomplished but it all still depends on our luck.
If we are not lucky enough, we can't still fulfill the wager requirement and we will fail to get the bonus. If they offer free spins without the need of depositing then that was great and worth a shot because at the end, we still have nothing to lose here. Deposit bonus are only optional and can always be ignored. Don't worry there are no more hidden terms if you win with your deposit.
We are not forced to deposit a large amount, but because we are participating in a certain promotion, we must deposit a minimum amount to be able to participate in that promotion and there are other conditions that we must know so that we don't make a mistake or we are unable to follow the requirements.
It is very rare for a casino to offer free spins with no deposit required. And if there is, the casino must have other conditions that we must comply with, usually those that are difficult for us. This is where we don't need to try to participate in every promotion and only really choose promotions that we can afford. And this is also to limit the use of money that we will use for gambling.
