The thing is, the first users didn't get all the first ones.
Bitcoin was in Slashdot more than two years ago. It is open source, anyone could download the software and mine on their CPU.
Mt. Gox has been open for even longer. Anyone, anywhere in the world could and still can buy on the exchanges. There's no members-only trading.
If you bought after Slashdot you would have paid around a dime or less. But Slashdot readers called it a ponzi scam and didn't take it seriously.
You could have bought thousands of bitcoins at a dollar when Steve Gibson talked about it in February 2011. But Leo poo-pooh'd it "Not government issued" he balked.
Then again, you could have bought bitcoins at $30 after the July 2011 bubble, and today be down by 66% yet and still be bitter.
That's the nature of speculation. Nobody knows if bitcoin will increase or decrease in value. But it definitely isn't a ponzi. Ponzi means paying dividends to early investors, using funds from later investors. Everyone who held bitcoins yesterday when they were $9.20 could have sold today at $11. Everyone, not just the early miners.
Today, just like a year ago, mining will generate bitcoins at a little more than the cost of electricity to generate them. If you want bitcoins, then mine, buy, or stand on the sidelines.
Just don't bitch when it hits $100.
