highroll_piKlLong time lurker here, but I figured I would share what I look at before signing up anywhere. After trying maybe a dozen sites I learned to read the small print first.
I always start with licensing: see which authority is listed in the footer, and whether they actually accept players from your country. 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 the bonus usually expires in a week or two. A good recent review that covers all of this is here [url=http://jobboard.piasd.org/author/marcus173826/]Craybet[/url] before you deposit anything.
I play almost only on my phone, so I check how the lobby works on a small screen. Support matters too: a real human reply beats a bot loop.
Hope this helps someone. Treat it as entertainment, not income.
