anyone ever gotten more bonus money than their original deposit

This might sound odd but has anyone ever deposited and then gotten a bigger bonus than what they put in? Like say you send in a hundred bucks and next thing you know the bonus is like 150, not matching exactly. Most of the places I use stick to that straight 100% match thing, sometimes less, but I heard from a guy at a live dealer table that some crypto casinos go crazy with the math, especially if you use a random altcoin or hit their “happy hour” window. I haven’t tried anything except bitcoin so I’m starting to wonder if I’m missing out.

Also, is this just a weird error or some kind of sneaky promo? I don’t trust anything that feels too easy after I got stung by that cashback offer that took a week to unlock. Someone else run into this or is my poker buddy just making stuff up while stacking chips?
