Your bonuses only gets bigger if you wager a higher amount of money, for people like me the bonus part is always not enough, because I prefer playing with low amount of money, it's even why bonuses don't look that interesting to me anymore after I found out that big players are the ones that benefits the most from bonuses.

Welcome bonuses, deposit bonuses, these two are what I care about, so yes bonus is a very attractive offers from online casinos, bonuses are very important.
