As a gambling beginner, to avoid unnecessary dramas I think it's better to avoid using any casino rating platforms for choosing the right casinos for you because the data they will use to rate each casino might be outdated already, you need a platform where constant users of casinos are dropping their experience from time to time, if a casino starts hitting their customers with scammish behaviour you won't know in time until after you are already a victim.
This is why I will always recommend this forum for beginners instead of any third-party casino rating websites, they just aren't always accurate, I started feeling like gambling when I joined this forum, not because of some reviews online that's probably created after they get paid, I mean who would know anyway?
There is no point looking elsewhere for online casinos you can use for gambling, there are too many on this forum that has good reviews and good user base where nothing will be going on behind closed door without you knowing a thing, I appreciate your effort OP but this isn't for me, I am satisfied with the casinos I knew through this forum.
There's also some probability that the casino ratings site received payment in exchange for listing.
Plus no sers, I'm not making an accusation, merely saying "perhaps". Because why would a very unpopular casino in the forum get a good rating from crypto ranking sites?
¯\_(ツ)_/¯
Plus if you're a Bitcoin gambling newbie in BitcoinTalk just use the signature campaign managers as a guide. Campaign managers are incetivized to be honest, therefore the casinos they promote have a higher probability for trustworthiness.
