BITCOINS WILL NEVER DIE.
NEVER
NEVER
NEVER
Even if SHA-256 gets cracked (via quantum computing) the blockchain can and will be upgraded...
Now, Bitcoins price can crash at any moment

.
I am glad that bitcoin will survive. It's a fantastic idea. But, I also don't want the money I put into it to have
less purchasing power over time.
I sold at 11. I have more purchasing power. I day trade until it falls. Then I speculate (unless its very volatile). I don't see any huge upswing in value until exchanges provide insurance to users and until sites like bitcoindeals really get off the ground.
