Long time lurker here, so here is what I look at before signing up anywhere. After trying maybe a dozen sites I stopped going by ads alone.
First thing is the licence: see which authority is listed in the footer, because some sites quietly block certain regions. Next come deposits and withdrawals: crypto is a plus but not a must, and cashout times should be listed up front.
Never judge a site by the bonus alone. Read the wagering and the max bet rule, and the bonus usually expires in a week or two. A useful overview with bonus rules, app info and payment methods is worth a read here [url=https://climaxconnection.com/forum/26/general-topics/9460/what-to-check-before-joining-legionbet-in-2026]legionbet casino[/url] before you deposit anything.
Most of my sessions are on mobile, so I check how the lobby works on a small screen. Test the live chat before depositing: if they answer in a couple of minutes that is a good sign.
That is about it. Only play with money you can afford to lose.
