Thanks for the info. Looks like I am five years too late. Looks like if im interested in investing just for the possibility that a BTC might be worth 10,000usd one day, Ill just have to buy them.

I read them all. It gives me the idea that bit coin mining is not going on at all now?

I stumbled across bit coin mining. I do have a fast computer with an i7. I want to mine for bit coins on the side, Not to sell out at the current rate but to keep them. Maybe one day they will be worth over $10,000. Are there any external GPU that are worth the effort of mining bitcoins?
