Well I wasn't complaining about bitcoins but interesting point
I was asking what you think the impact would be along various fields
In Economics the effect of Deflationary Currency in the long run
In Politics a libertarian view on finance and the differences from Central Banks controlling income
In Philosophy a way to ensure a fairer distribution of income
In Privacy Law having a method of exchange that is able to be traded between individuals freely as long as the government does not have your key
All leading to a full point on what is Bitcoin really
Of course there are always these type of currencies as well
