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.
Being able to get a bonus is certainly fun because that's what people want, but unfortunately, many of us don't know the terms and conditions. Maybe we are looking for a welcome bonus, deposit bonus, weekly bonus or other bonuses, but make sure we understand the terms and conditions. Maybe our bonus can get bigger by using big money, but maybe that's not always true because certain bonuses have wagering requirements that every gambler must meet. So if you can accept the term and conditions, you may get the bonus.
