highroll_icKlLong time lurker here, so here is how I pick an online casino these days. After trying maybe a dozen sites I learned to read the small print first.
I always start with licensing: check who regulates the site, and whether they actually accept players from your country. Next come deposits and withdrawals: 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. Read the wagering and the max bet rule, and the bonus usually expires in a week or two. A good recent review that covers all of this can be found here [url=https://guidehub0ef599.omeka.net/items/show/48]Just Casino[/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. Test the live chat before depositing: slow or scripted answers usually mean trouble later.
Hope this helps someone. Only play with money you can afford to lose.
