It doesn't sound straightforward to me. I saw the ads and assumed it would be credit and require a deposit of near the size of the bonus to be kept for X days and maybe bet at least once, but needing to risk $25k on bets you're very likely to lose (I honestly can't remember if 1-3 means 0.25 or 0.75 probability, or neither, but even 0.75 is going to be hard to keep) wasn't expected. I'm sure it's all there in the fine print when you go to sign up, but the ads pretty much just yell at you "we're giving you free money to gamble with!".
I never saw the ads, but I have gambled on a couple of online casinos that use crypto, and that was how their bonuses worked. It was pretty easy to hit the targets. If you bet the same $200 ten times then you're at $2,000 gambled. I don't know anything about sports betting, so maybe that's different.
