    Play µBIT is play money.

    Play micro BitOil (µBIT) is a points system for fun and learning. It is not a cryptocurrency, not a security and not money. It has no cash value and cannot be bought, sold, traded, transferred or withdrawn. It is separate from Real BitOil, which does not exist yet, and holding play µBIT carries no right or promise to receive anything in the future. We may change the rules or reset balances at any time.
