Sigh, you guys at looking at Bitcoin from only one angle when there is multiple angles.

All you are looking at it from is simply, 'How can I make money from this'. Bitcoin is way bigger than that. Your not just mining to make money, your mining to make the whole system work. As we all know, the value will plateu and stay that way at some point, from then it won't be profitable to mine, but miners will still be needed to valid the transactions. That is what is important.

If someone told me I needed to invest in Bitcoin, it wouldnt be to buy a fast GPU, it would be to buy X amount of a Bitcoin with real money. Not saying I'd do that, a lil risky as we know. But the value of Bitcoin isnt you can make money, its the ability to transfer money across.
