So is there any good centralized platform where we can trust the feedback about different casinos?
Yes, one can see the reviews about the particular gambling site individually on the ANN threads on this forum however there should be a consolidated review about major gambling sites which should be trusted by the majority of the gamblers.
I don't know which review platform is good but what I know is BTCGOSU and Gamblingbro they are on this forum and to say their reviews are real means their experience has been tested so they give a decent review.
True we always see reviews from ANN forum threads, I know more there but to combine with big gambler reviews I don't know as they always don't show up here.
