TL;DR: The number of bitcoin holders has just surpassed 2 million mark! The growth is happening in the holdings of 70 bitcoins or less, especially in micro-holdings of 1 bitcoin or less.
Great news. So Bitcoiners are now 0.03% of the world population. Imagine what could happen when 3% of the world population becomes Bitcoiners. The exchange value can increase by 10 to 100 times.
