Been reading this board for a while, thought I would drop what I look at before signing up anywhere. After getting burned once or twice I stopped going by ads alone.
First thing is the licence: find the licence number and look it up, and if your country is on the allowed list. 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 good recent review that covers all of this is here [url=https://www.dibiz.com/activation+dbz35b2d7cbeb]bonus at Trino Casino[/url] so you know what you are signing up for.
Most of my sessions are on mobile, and a good site loads fast and does not log you out every five minutes. Support matters too: slow or scripted answers usually mean trouble later.
Anyway, that is my routine. Set a budget and stick to it.
