Reason I like Bovada #4:
It's fair and safe
The best way to avoid losing money by gambling is to not gamble in the first place. That goes double online, because online gambling is mostly unregulated in the U.S. That means the casinos serving the whole U.S. don't answer to anyone. If you have a problem with a casino (like they won't pay you), then you're usually out of luck. I can't count how many players have written to ask me for help because they didn't get paid by some other casino. (Not that I helped them, it's not what I do—if a dodgy casino won't pay you then you're on your own.)
So if you're intent on gambling online, then the #1 most important thing is to pick a good casino. The good ones know they make more money with fair games and consistent payouts than the dodgy casinos, because fair play means repeat customers and good word-of-mouth referrals. It's no coincidence that the most successful online casinos are the ones that focus on their players.
Many casinos try to find excuses to not pay winning players, especially players who have won big. Outright cheating (rigged games) is pretty rare, but it happens. Either way, if you have a problem with most U.S.-facing online casinos, you're usually out of luck.
This is another reason why Bovada is the only online casino I've accepted advertising from for over 15 years. They use industry-standard software, it's absolutely fair, and players get their payouts, consistently. I have a choice in whom I advertise, so I purposefully picked a casino with a good reputation where I'm confident my readers will have a good experience.
To be clear, Bovada's not perfect. Once they got duped by a bad vendor (Betsoft) who provided progressive slots whose jackpots weren't winnable. When I discovered this I alerted Bovada, and they pulled all the Betsoft games from the site, but I thought they were slow to do so and didn't offer proper restitution to affected players. (more on this) Still, even with this incident, their overall history is better than most; as just one example, there are many other casinos still offering Betsoft's questionable games.
Another good thing about Bovada is that they allow me to mediate if one of my readers clicks over to them, plays the games, and has a problem they can't get Bovada to resolve. My time is valuable and I wouldn't offer that service if I had to do it very often. I think I've gotten maybe one or two inquiries from affected players in the 15+ years I've been advertising Bovada.
Bottom line: I'm confident that Bovada is fair and reasonably safe. You might have a good experience with another casino...and you might not. I trust Bovada, and that's why I picked them.
