Mostly a reader, rarely post, but I figured I would share what I look at before signing up anywhere. After trying maybe a dozen sites I stopped trusting the big banners.
First thing is the licence: see which authority is listed in the footer, and whether they actually accept players from your country. After that I look at banking: I want at least one fast e-wallet option, and there should be no weird fees on cashouts.
The welcome offer is where most people get caught. Read the wagering and the max bet rule, and the bonus usually expires in a week or two. A decent independent write-up with the current terms is here [url=https://www.efunda.com/members/people/show_people.cfm?Usr=martinez67e61f]cray bet[/url] before you deposit anything.
Most of my sessions are on mobile, so I check how the lobby works on a small screen. Ask support one simple question first: slow or scripted answers usually mean trouble later.
That is about it. Set a budget and stick to it.
