What if we would say yes to all on them? I guess you have one choice qurrently to work on it well. I would say I choose PVP/Multiplayer because many popular dice website already offers altcoins but no one has PVP/Multiplayer (correct me if I am wrong, I talk about famous dice websites) or at least I haven't heared. It will be good and will attract more players, it's another experience and feeling when you play PVP and when you play alone with servers.
