It will reach $10,000 easy. Here is why:
1. At $10,000 * 21million coins: $210 billion market cap = companies listed on the stock exchange
2. At $100,000 * 21million coins: $2.1 trillion market cap = market cap of gold
3. At $1,000,000 * 21 million coins: $21 trillion market cap = leverage US GDP
Scenario 1: Bitcoin is equivalent to less than most companies listed on the stock exchange. Today's bitcoin media hype and value potential > companies on the stock exchange. We could see the $10,000 mark IF the hype remains the same and merchant adoption continues to rise. See: Bitcoinpulse
Scenario 2: Bitcoin can replace gold, because unlike gold, bitcoin has an intrinsic store of value. You can sell it for any currency anywhere in the world instantly. Whereas gold has a speculative value of roughly $200 an ounce, and the remaining $1000 is speculation. I can't fly to London with an OZ of gold and start chipping it in exchange for goods. And pawn shops won't pay $1200 for an OZ of gold. Fact.
Scenario 3: This is a long haul, but what if governments would leverage every printed note in exchange for bitcoin. The US wants to print $10 million dollars worth of notes? ok, in exchange buy bitcoins. So that if ever you wanted to cash out your dollars, there is real intrinsic value for them. That was the idea for Gold, but it never seemed to work.
