I think it would be necessary to add 24/7 live support on your platform. It's just a suggestion that helps your users a lot.
They already have a live chat but I had to make an account to check that, it isn't available to non-members which makes sense I think. I got a reply within moments of messaging the live support so I believe they are doing good in that department but the only area of concern is their trust here at bitcointalk. I like the design and everything on duckdice but I was and still am afraid to play because I don't know if I will be able to get my winnings back if I win.
Since they have a few more coins apart from BTC, I might deposit and play with some dogecoins. By the way, I was impressed to see 1000+ members online, as per their stats on top, because even stake and other prominent casinos cannot gather that much attention all the time. I hope the stats are real

.
My mistake that I have not seen, technical support which is 24/7 is necessary. Moderators are not constantly on chat but it is very good that you have it.
