Funny thing,
I actually learned about bitcoin doing research for a law class. It was regarding subpoenas attempting to gather information on anonymous internet users for civil lawsuits.
When I came across BTC, I instantly became interested. I wish I came across BTC a lot earlier.
I started mining a couple months ago -- I purchased one video card not really that great of speed. It is an ATI Radeon 6770 so I get around 200 MH/s..I am probably just wasting electricity rather than making anything..
