AMD quietly drops Radeon HD 7990 price to $700

[FranciscoNET]

Many of my fellow virtual miners have hundreds of AMD graphics card!

Unless you can tell me there is a practical purpose behind making all those cards process 24/7, I personally don't care how many you use mining bitcoins. At least with folding@home there was a cause which was finding a cure for decease. What is the cause with mining bitcoins? You would be a fool to make your machine process 24/7, if you didn't know what all that processing was used for. I for one would like someone to explain what this cause is.

There is no cause (its a business decision to begin mining cryptocurrencies), you have a lot of research to do in terms of cryptocurrencies. Mining Bitcoins, (now Litecoins because it is more profitable to mine Litecoins with a GPU) is all about finding a new block of new bitcoins or Litecoins, and you get that block for yourself because of your efforts. These blocks are then circulated onto the cryptocurrency network, contributing for more funds to be available in total, there is more funds in circulation that can be use for trading purposes thanks to people that are mining that actively finds new coins by having their GPU solve complex mathematical problems. So, the more people there are mining, the more value these currencies acquires. That's why 1 (one) bitcoin today equates to over $850 dollars. Of course, if you dont want to mine, you can always directly invest in purchasing bitcoins and enjoy your return on investment in a few more months -- a guy in Norway who purcahsed $27 worth of bitcoins in year 2010 and forgot about it till recently, today he is a millionaire -- talk about return on investment.
