I think there was only ever one casino you should actually avoid (based on this forum that is). 1xbit is absolutely notorious for its reputation and afaik, it's still running. So just avoid that and I reckon you'd be fine with most recommendations in this place. First rep already gave out btcgosu so you should be good to go, that site has a lot of good and reputable casinos already. If you're still curious about the casino themselves, either visit the site or the campaign page they have in this forum (They usually have one, especially those you see with signatures). Should give you a general idea of the casino imo.
