Of all the other cryptocurrencies you could choose as payment method, why did you pick ethereum? I know it's second to bitcoin in terms of market capitalization and maybe popularity BUT THE FEES!
Btc transaction fees is already quite high when sending in most days [weekdays] but Eth is just the same or could be even more expensive. Perhaps you can add another alternative there such as Litecoin or Doge.
I'm also looking for this option and honestly I stop gambling because of the fees and since my capital is just small, I can't deal with too much fees in the market right now.
Anyway, this is another great crypto gambling and I see the CS:GO where you can buy items using your withdrawal. I don't know why they include this as their option but gamers will love this one for sure. Will try to know more about this site and see if its a real instant deposit and withdrawal.
