Are you still supporting new casinos even if you're already playing in so many casinos do you still have room for new casino to deposit and play?
I have a very suspicious personality, so I tend to wait until a service provider, in this case an online gambling casino, prove themselves with at the very least 1 years worth of online time with absolutely no accusations, bugs, hacks or other problems. Then and only then do they achieve a "level 1" kind of trust in my eyes and I would consider putting up to 100 dollars worth of crypto into their platform.
Too many scammers lurking around, trust is becoming something which should not be given away easily.
There are other ways they can improve my trust rating in them, for example, if they are active in their community and have legitimate audits.
That aside, most casinos are quite lazy copy/paste versions of older and better casinos.
