Just use bitcoin from the website. Doesn't matter program you use, the odds of getting a block together by yourself is like 1 and 310289310293801293 give or take a few 120391203918230. Even if you run your program every day for 365 days you could get 0 blocks, but lets say your lucky and you generate one block, that gives you 50 bitcoins, and if the first post was true about currency exchange then you just made $1000. I do not have my hopes up but I do run it in the background. I have an i7 940 (8 processors) and 2 Radeon HD 4850's crossfired. I should be learning pretty quickly but even running it for 8 hours a day it could take me a few years to get one block...lol

Also, do not buy bitcoins unless you want to buy something right away with a bitcoin, its pointless. Also, if your lucky and you get a block together, there is a website that will trade bitcoins for gold and silver. Take Alex's advice and invest in real physical precious metals. Cause when our economy shuts down because of greed and abuse of funds, precious metals will be the only thing trusted to buy goods.
