Does this still use the same token system as Steemit?
Is there still the internal exchange between Steem and Steem Dollars, including the power-up and power-down features?
Do you need to keep the mining machine open, as I wouldn't want to waste energy?

I basically want to create a personal social network for a game with all the same features of Steem. I would then incorporate auctions and stuff for ingame items using Steem hopefully.

Thanks so much for answering my questions.
