I never really cared about all they hype behind Web 3.0 which is why my interest in crypto gambling sites adopting this stuff never really rose though I did check them out now and then, but didn't find any major differences.
What matters more to me when investing in these sites is how reliable they are, no KYC, low house edge, great promotions etc.
That's the main concern for many gamblers but at this time many legit casinos have implemented KYC norms for the players and if we have to continue our gambling journey with them we must have to go through providing details but for small gamblers like us it's not too much complex.And yes promotions are the way of keeping up players interest in the casino and making profits as house have edge always.
