Look at it from marketcap value, not from price per bitcoin. As the marketcap goes up which is inevitable, so will the price. Fixed amount of bitcoin will insure quick price rise. If we hit $50 Billion market cap this year we're looking at around $4000 / BTC
Price is important but this is a way more important factor in the rising price of Bitcoin that so few people seem to grasp. Bitcoin from $1 to $100 was $1B is new money. From $100 to $1000 is was ~$10 billion in new money. The problem with exponential growth is ~$100B in new money for $10k for Bitcoin.
"$1B isn't so much money really, but $10B is just insane, you'd have to be nuts to believe that could happen in less than a year." - You, about one year ago.
