Ardor at $0,50 is a steal. The total market cap is sure to cross 1 trillion USD at some point in 2018. Since Ardor is likely to become recognized as a store of value (due to being POS and the native incentive token of a platform with numerous child-chains), I don't see why it can't seize at least 1% of the total mcap. In that case, Ardor will have a 10 billion USD mcap, or approximately $10 per Ardor.
