punter_svorLong time lurker here, but I figured I would share how I pick an online casino these days. After getting burned once or twice I stopped going by ads alone.
I always start with licensing: see which authority is listed in the footer, and whether they actually accept players from your country. After that I look at banking: crypto is a plus but not a must, and the withdrawal limits need to be written clearly.
Never judge a site by the bonus alone. Wagering of 35x or 40x is normal, 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://vocal.media/authors/rolletto]bonus at Rolletto[/url] before you deposit anything.
On mobile I mostly use the browser version, and if there is an app I make sure it comes from the official page. Support matters too: a real human reply beats a bot loop.
Hope this helps someone. Only play with money you can afford to lose.
