It looks nice. Info a bit short but clear. The list is too short: I don’t see 777coin and bitvest.io or many others that you can find here on the forum.
Its clear that this list do only matter on OP's preference not on generally listing all gambling sites in the market and i have seen it do shows sports betting site and a casinos but im not really familiar with that CSGOPOLYGON and GANDOM.
That is the concern I have about websites that focus on lists and reviews about certain crypto service providers because its mostly based on subjectivity rather than objectivity and there is no way that Op would say he has consistently played on those sites to make a conclusion on how they operate. But if its a platform that gives room for others opinion to also post their reviews, updated ones it would be better but it seems its just a by the side project, get the required traffic, then get ads to pay the bills nothing extra.
the sites like that do not focus on objectivity or subjectivity
they focus on affiliativity solely-if a site brings comission,it is good
usually,the top sites and relatively unknown,new sites are the best ones to promote
there is nothing new about platforms like that,they are all based on either ads to generate profit or affiliate comission or the combination of the above
