I can’t really relate when it comes to bonuses since I’m not a big gambler, maybe for VIPs, bonuses matter a lot. But when it comes to sports betting, I always make sure I’m betting with a sportsbook that offers competitive odds. I’ve seen some bookies offering odds like 1.85, while others offer 1.90. That’s a 5% difference in returns if we win, and I think that’s something we definitely shouldn’t overlook.
It doesn't matter if your casino level is low; Eg, a free bet of $2.5 - $5 value can be the start for being involved more in this casino. It's money that the casino will get back, no matter what. It's up to the player where he will bet them. He can get 100% back, and most likely, he will continue playing in the casino that gave him this "opportunity". I mean that the casino won't lose and it will win more clients. If this is combined with better odds and spreads, then, IMO attracting more players is guaranteed.
