Claiming free bonuses with high wagering requirement from casino to other casinos will be wasting your time and energy only imho. The probability to complete the wagering requirement is so low, so taking it for fun only on your spare time is better instead of forcing yourself to claim it everywhere.
Quite true. Even your efforts will be wasted and I believe those bonuses they are giving are not intended for you to win but for you to stay attracted and keep the excitement within yourselves. But the truth is, it is really hard to keep your track and to achieve your goal of winning since the bonuses cannot be withdrawn without a deposited fund.
That's why I never reached the wagering requirement because I don't want to force myself, I know they are not that worth compared the amount of money I will risk. In addition, I played with different gambling sites for better experience, I do that because I'm gambling for fun.
Gambling with the bonuses is good, and as mentioned in one of the quote the bonus provided is to keep the player active. This can be seen with the games we play very first, possibly most of the time users will get a winning on few consecutive games and further users experience loss. This too is the way of creating a positive hope to win and play big. In my opinion it is not bad to spend on gambling, if you're aware about the do's and don't with gambling.
