Right now bitcoins can be divided into smaller denominations. The smallest being 0.00000001 as everyone says. This is controlled by or coded or whatever in to the blockchain. If whoever seems to govern bitcoin, (Gavin or whoever), wants to allow bitcoins to be divided into smaller denominations, example; 0.0000000000000001 or 0.0000000000000000000000000000000000000000001 can this be done?
