actually we must not come to the trap of gambling site that uses bonuses promo but the truth is? they are the one who will only benefits because we need to deposit and play(and surely will lose) and they will gather our money without winning that said bonuses literally.
so best to learn from it and never fall from those traps.
How can even you assure people that they will lose? Do you mean to say that there is no chance for people to win in gambling? I myself do not like bonuses (deposit bonus) but you cant deny the fact that there are some gamblers who managed to make profit from such bonuses after completing the big wagering requirement. I cant agree that bonuses is trap, I have no idea why you can consider bonuses as a trap. It can be a trap if there is hidden term for the bonus but I'm sure reputable casino reveal all the terms of the bonuses publicly. It can be a trap as well if you do not read the terms before taking the bonus so you feel of being trapped because of your own mistake of not reading the terms.
