It's good that you don't accept fiat-based platforms or bank cards.
But what do you mean by "Only crypto. Only hardcore?" Do you mean Bitcoin, Ethereum, Monero, etc.?
What exactly do you mean?
Only crypto means only crypto. Yes, they do list casinos that is exclusively for crypto users. No matter what crypto it is. It could be only Bitcoin, or only doge coin, or support multiple cryptos. I have submitted a couple of websites and almost ten of them got accepted by them. I mistakenly submitted some casinos that support fiat and they rejected that with a good explanation.
With this site, it makes job of signature campaign managers more easily for finding hidden gems in online gambling industry, though they will still do many further checking steps.
Correct. I am already in contact with a few projects and I think I will be their regular visitor.
