There are some people who are of the opinion whether only the online casinos that provide free bonuses are honest. They believe that the others are not honest. Now this is a strange way of thinking. Just because some online casinos offer free bonuses does not necessarily make them honest.
What if I said that the online casinos that are providing free bonuses are giving the same just to lure you? Once you have exhausted these bonuses and start playing with your own money, they will start cheating you. Ask your friends who have played on a particular site to ascertain whether that particular online casino is honest or not. This is the safest and best way to know.
