Bonus sports betting integration: why is this so complicated

so i'm messing around trying to stack a couple of these bonuses and wow, the whole thing is a mess. one site says my bonus credits work for “all markets” but when i try a live bet, suddenly it’s real money only. another one, i get the free bet, but gotta run it through a weird combo market before it counts. honestly feels like they make the rules just confusing enough so half the people give up haha. not sure if it’s just me, but integrating crypto on top just adds another layer of delays and weird terms that nobody really explains. would love to hear if anyone’s actually cracked this code or is it just all designed to slow us down?
