it will depend on the financial budget that we have set. If the minimum deposit exceeds the budget, we don't need to deposit it just to get the bonus, but only deposit enough. But some people want to try to deposit more to get that bonus because they see the bonus as very tempting, so they decide to deposit more to get it. Maybe we can try it occasionally if we want to try to get a bigger bonus. But it is not worth doing if our gambling budget is limited.
I think it's a risk that people shouldn't take about gambling. If you have a limit about your deposits, keep that in and do not go for the extra bonus, in the end you will lose that too so you shouldn't be really caring about the end result. I am not saying that it's bad, but it is certainly not a good way of making money neither, it's going to end up being much worse for you if you deposit more than you should and end up losing it.
I feel like the best thing to do would be staying away from it and just deposit your normal amount and gamble the way you always do and if you end up losing at least it was an amount you were willing to lose to begin with and that's it.
Bonuses is one of the methods of casinos that makes their gamblers deposit more, It is proven effective as it is still be done to this date and I assume people are taking the bait. Basically people who doesn't have any limits or any plans on how to spend their money and time on a casino are basically the one who tends to spend more and taking the bonuses like this. I don't think it's bad to take bonuses like this as long as you have a proper control with yourself and you know what you are currently doing like not overspending and not overstaying on the casino you are playing.
