Yes, when it comes to deposit bonuses or other bonuses, all casinos have nearly identical methods, with requirements that I find difficult to meet. In reality, this is how casinos make their profit. If gamblers are curious and try to chase a bonus, they'll try to deposit again just to chase it, which is very difficult to achieve. However, if the bonus isn't too large and has a wagering requirement of x25 or other requirements, or even x15 with different conditions, it's still possible to chase it with just a small bonus.
I also sometimes ignore bonuses offered or given by casinos because the requirements are something I feel I'll never be able to meet, but sometimes I take advantage of them just to have fun without using my own funds.
The requirements I usually see in bets made by my friends who choose the bonus feature usually involve a different minimum withdrawal. For example, without selecting the bonus, we can withdraw the predetermined amount as usual, but because of the bonus, the minimum withdrawal is different, being higher than usual.
Personally, I don't know when I'll try it, but I haven't really thought about it, so I just bet with the capital I deposited. Because even if I'm lucky, I'll still win and withdraw my winnings.
