they're one of the top bookies in the eSports betting scene. They accept a bunch of cryptos like monero, btc, eth, tron and more via bitpay...thing is that last time i checked you had to KYC for withdrawals which kinda defeats the purpose of using cryptos (maybe the changed this policy? idk)
^That is enough reason to not want to use them for many people that are going to use crypto for payment, I mean if privacy doesn't matter to you and you have absolutely no problem going through KYC process there are tons of other reputable casino websites that you can try that accept Fiat only as well.
I'm 100% sure you can easily find a good trusted casino website in Gambling section if you read their official threads and members posts there, many of them even have active customer supports here in the forum which you can reach whenever you got a problem or have a question about them.
