Sometimes not having a demo play pisses me of

But it doesn't really matter a lot.
I would be annoyed if the casino will hold the funds without having any reason that makes sense. Luckily, I'm happy that I have no experience with that. All of my withdrawal requests are processed and confirmed within minutes, that one is a huge plus factor.
Giveaways, of course, codes, contests, etc.
This is why we are here to drop some experience about some certain casinos which would always refuse to pay customers there funds. There many things that do annoyed me about some crypto casino which is an attempt to scam. It is really painful to play a games and make winnings and finally the casino decided not to pay. This is where many things goes wrong because this will alway tarnish the image of the casino and other gamblers that might be using the casino for long might be scared of keep their funds to avoid been scammed.
