So this is a game coin?

Yes, so Rustbits are a tradeable counterparty asset on the blockchain, they are also used in the game (SP:Age of Rust) and act as a premium current in the game. It will be able to be earned as a reward by solving game challenges and puzzles, tipped from other players, dropped when killed, and picked up by other lucky players, etc.  Rustbits can also be used to purchase blockchain cards which you can trade, collect, or use in the game. The game is free to play, so you don't need rustbits to play the game.  At the end of the token sale, all the unsold rustbits that are in the ICO pool will be burnt.

What day of the week do you list our stakes on the spreadsheet, I'm done sharing/retweeting and liking the posts/tweets. Please update mine. Thanks

I joined to Twitter and Facebook bounty

To make things easier for everyone on the campaign, we have a campaign manager now, Jemzx00, who will help keep things updated. Jemzx00 will be updating participants who joined on all campaigns daily and update the stakes for signature campaign weekly while the twitter and facebook stakes will be updated at the end of the Campaign.

I'll do an update today though, so come back in a few hours and check the twitter sheet.
