The first time I read this thread, I took a look at all the casinos on the list and if I remember correctly, all of them do, indeed, support crypto payments. However they are not pure crypto casinos as most, if not all, of them started as fiat casinos then started supporting cryptocurrencies as an alternative payment method.
BTW, the info on the website about which cryptos are supported by each casino is not accurate or outdated. e.g: on the website it says Vegas casino supports only bitcoin while it actually supports btc, eth, LTC and usdt.
