lucky_grmtLong time lurker here, so here is what I look at before signing up anywhere. After a few bad experiences I stopped trusting the big banners.
First thing is the licence: find the licence number and look it up, and if your country is on the allowed list. Next come deposits and withdrawals: crypto is a plus but not a must, and cashout times should be listed up front.
Never judge a site by the bonus alone. Anything above 40x rollover is a red flag for me, and some games count less towards it. A good recent review that covers all of this is here [url=http://forum.casino.digitalleisure.com/member.php?action=profile&uid=4207]Lottoland[/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. Support matters too: if they answer in a couple of minutes that is a good sign.
Anyway, that is my routine. Treat it as entertainment, not income.
