Long time lurker here, but I figured I would share how I pick an online casino these days. After trying maybe a dozen sites I stopped going by ads alone.
Licence comes first for me: check who regulates the site, because some sites quietly block certain regions. After that I look at banking: crypto is a plus but not a must, and there should be no weird fees on cashouts.
Never judge a site by the bonus alone. Anything above 40x rollover is a red flag for me, and the bonus usually expires in a week or two. A useful overview with bonus rules, app info and payment methods can be found here [url=https://www.shippingexplorer.net/en/user/george4b0fe7/354876]play at Gamblezen[/url] and it saved me some time.
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.
Anyway, that is my routine. Set a budget and stick to it.
