Non-Sticky vs Sticky Bonuses: Why do high percentage offers usually trap your real money?

I see so many new players getting excited about 400% welcome bonuses, but they do not realize they are locking their actual deposit until they wager a fortune.

I am building a personal list of "parachute" or non-sticky bonus casinos for 2026 where you can forfeit the bonus and withdraw if you hit big with your own cash early on. Does anyone have verified sites that still offer this, or has everyone switched to the wager-locked model?
