There is no need to run after each and every bonus. We need to be careful in selecting which bonus is suitable for us and which one should be avoid.
Let me give you an example. Lets suppose the gambling site is giving bonus on deposit with high wagering requirements. Now you already had a plan to deposit at the casino, so you may deposit and avail this bonus. However if you already have funds at gambling site, depositing only to get this bonus may not be the right idea.
After depositing for the sake of getting a bonus and when you win then withdrawing money you cannot do it because you have to play and bet according to the amount of the bonus received, usually when the target is difficult to achieve and you cannot withdraw the money back then play the result you get is defeat and the money deposited is also used up along with bonuses.
There are also many terms and regulations that are sometimes overlooked to read, well, even though I also never had time to read them, at least take the important points there, but it's also true that being a gambler, it's enough to play and deposit without having to expect bonuses, make sure the casino has a good reputation. good before making a deposit and don't be tempted by bonuses, especially in new casinos, should be avoided.
