Hello @pompe72! =)
We're currently still on thinking over the process to make it compliant for the Mojang EULA. Once the Skyroad Token would be tradeable and exchangeable with steem-engine, we would violate the EULA, unfortunately. We might come up with another idea to earn STEEM on the server besides the contests very soon. (Ingame money burning functionality, which creates a comment here on steem, which then gets upvoted or something like that which no direct message about money on the game side)
