1. Ponzi scheme in current idea. Let's look 10 years afterwards. Everyone know bitcoin, everyone is exchanging his own money in country to BTC. What happens? BTC have value i.e. $10,000ea so last adopters will buy it for insane price, where early adopters will be able to build even their own country out of their BTC's? Sick. They did nothing to the society to have that workforce for nothing. Sorry - it's just ponzi scheme.
You don't appear to know what a Ponzi scheme is, and you don't seem to have a good understanding of how Bitcoin works.
A Ponzi scheme involves lying about how much capital there is. You might invest $1 million, and then I might lie and tell you that I've managed to double your investment, when in reality I've done nothing. It's the act of deliberately misrepresenting the amount of capital available that makes it fraud.
Bitcoins cannot be a Ponzi scheme in themselves, because there's no one person who decides their worth. Bitcoins are, at worst, merely a risky investment.
Secondly, you seem to assume that everyone will buy up bitcoins and hoard them, but the value of bitcoins derives from their ability to transfer wealth without the need for an intermediate financial institution. If no-one's using bitcoins, then they have no worth beyond speculation, and you can't grow an economy from scratch to $10 billion on speculation alone.
If bitcoins ever get to $10,000 1 BTC, then it will be because people are regularly using them to transfer money. It's the infrastructure and social following that would give bitcoins their value; we won't ever get into a situation where billions of dollars are invested in a currency no-one uses.
Finally, you seem to be upset that early adopters stand to gain large amounts of money "for nothing" if bitcoin succeeds. You don't seem to appreciate that anyone investing in bitcoins at this point is taking a risk. If you invest $1000 in bitcoins, then there's a strong possibility you'll lose your investment if the currency fails. The principle of high-risk/high-reward is nothing unusual.
