I think it is necessary to stablish the value of the Bitcoin. Today we don’t know if Bitcoin is a reserve of value as gold is, if Bitcoin is a practical way to pay on the internet, if is valid on non-virtual environments as FIAT money, etc.
This is the preliminary point to get stability in the value, of course few people more volatility and more sensibility to external factors (economic, political and regulation).
In my opinion the most important value of the Bitcoin is the technology itself, and its use on others business –not only in the money-. It will be necessary to developed these other business to get the real Bitcoin value and to stabilize it.
