Some gamblers may not take decentralized or centralized betting sites into account. Fiat betting sites also ask customers for KYC.
But I don't know, I don't really care to compare crypto betting and fiat betting. They develop their market based on their own sectors. Fiat betting sites still have their own fans. They reach customers who do not have crypto and are not knowledgeable about it.
Those of us who prefer crypto betting sites also use them and are happier because we have crypto. Otherwise, we might as well bet with Fiat.
Almost all of them asks for KYC but except the decentralized ones, they won't ask for it. But are there enough volumes to maintain these types of casinos?
I don't think that many of them are in existence today, except the known ones. I've been used to crypto betting.
There are more users I think with crypto betting nowadays but this is one advantage of us, we can be on both platforms.
