Why are countries in such a hurry to decide one way or the other, when Bitcoin's market cap is still very small in many of these countries? Can't they wait a year or two longer, and see where it goes and pass more appropriate laws after they've had a while to think about it? I imagine most people in Parliaments didn't even hear about Bitcoin until last month. So why rush to a decision now then?
