Mostly a reader, rarely post, thought I would drop how I pick an online casino these days. After trying maybe a dozen sites I stopped trusting the big banners.
Licence comes first for me: check who regulates the site, and if your country is on the allowed list. Then payments: crypto is a plus but not a must, and cashout times should be listed up front.
Bonuses are the tricky part. Anything above 40x rollover is a red flag for me, and the bonus usually expires in a week or two. A decent independent write-up with the current terms is here Gamblezen so you know what you are signing up for.
On mobile I mostly use the browser version, and if there is an app I make sure it comes from the official page. Ask support one simple question first: a real human reply beats a bot loop.
That is about it. Treat it as entertainment, not income.
