Long time lurker here, thought I would drop my short checklist for choosing a casino site. After a few bad experiences I stopped trusting the big banners.
First thing is the licence: find the licence number and look it up, because some sites quietly block certain regions. Next come deposits and withdrawals: crypto is a plus but not a must, and the withdrawal limits need to be written clearly.
Bonuses are the tricky part. 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 can be found here [url=https://legendary11.com/blogs/view/66308]Smash Casino[/url] before you deposit anything.
Most of my sessions are on mobile, and a good site loads fast and does not log you out every five minutes. Test the live chat before depositing: 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.
