Guys, I'm really no expert on economy, but to me it seems relatively simple: We replace our country's currency with bitcoins, eventually noone wants our country's currency anymore, leading to inflation. All gouvernments will do anything in their power to limit the use of bitcoins as much as possible imho. To me the question is WHEN they will act and HOW it is gonna influence the bitcoin popularity. It never hurt other p2p software, but people didn't pay money for that. Then again, people don't really pay money for bitcoins either, they generate them.
Scenario 1: Bitcoins become really popular, 1 billion people on the world by now earn bitcoins when the major gouvernments declare war on it. This leads to an uprising and eventually a civil war.
Scenario 2: The govs react quickly with very effective propaganda and the value of bitcoins will fall for a long time.
Scenario 3: The govs do all in their power, sooner or later, but the bitcoin market florishes nonetheless.
Today's btc value developement seems related to all those news reports if you ask me. I'm ofc hoping it'll rise and I wouldnt mind a civil war scenario either. Its about time we see some blood, at least where I live it is. Now think of some 3rd world countries...
