We're finally near completion of accepting altcoins at stake. We're doing final testing and will hopefully accept Ethereum this week! What coins do you want to see added?
Etherium,Litecoins,Dogecoins are the top ones to be added first IMHO
Monero and Dash would be nice to add,at some point later
not sure if there are new coins that deserve to be added,but for the owner I would look at the number of potential whales wagering in that coin(s) and the ease of integration
maybe have a look at Zcash,Peercoin and even,forgive me Lord,Bitcoin cash?
