I see BTC having (at a minimum) a similar value potential to previous paradigm shifts:

- FB social
- GOOG search
- MSFT, AAPL hardware

Or Banking:
- BAC
- CITI
etc

All these companies start at around $150B in valuation.

Bitcoin has a 99% MONOPOLY in crypto currencies.

There's a good chance for BTC to enter the 150B league in 4-7 years which would result in a Btc/Usd of around $10,000.
