Sticky vs non-sticky bonuses
If it’s sticky, i’d assume that bonus is forfeited when you withdraw, even if all you’re trying to take out is your own $100. Non-sticky usually means the bonus is separate, so your deposit may come out and the bonus stays put. But some terms still say a withdrawal cancels it, which is the annoying part. I’d check the cashout section before opting in, not just the wagering bit. Those rules can make a “matched” bonus a lot less straightforward than the headline makes it look.
