highroll_dsKlLong time lurker here, thought I would drop what I look at before signing up anywhere. 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, because some sites quietly block certain regions. Then payments: crypto is a plus but not a must, and cashout times should be listed up front.
Bonuses are the tricky part. Wagering of 35x or 40x is normal, and some games count less towards it. A good recent review that covers all of this can be found here [url=https://joy.link/cryptoplaypicks33d7#just4win-ca]bonus at Just Casino[/url] and it saved me some time.
On mobile I mostly use the browser version, and a good site loads fast and does not log you out every five minutes. Support matters too: if they answer in a couple of minutes that is a good sign.
Anyway, that is my routine. Set a budget and stick to it.
