Long time lurker here, so here is what I look at before signing up anywhere. After getting burned once or twice I stopped trusting the big banners.
First thing is the licence: check who regulates the site, 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 live tables often do not count at all. A decent independent write-up with the current terms is here visita il sito before you deposit anything.
I play almost only on my phone, and a good site loads fast and does not log you out every five minutes. Ask support one simple question first: if they answer in a couple of minutes that is a good sign.
Anyway, that is my routine. Treat it as entertainment, not income.
