It'll be interesting to see how this performs on GCN in the future, where optimizing for VLIW won't be part of the performance equation.

Bitcoin is NOT a ponzi scheme like the Dollar or the Euro because there's a finite number of them that can ever exist. Central banks can go on a printing spree like the Weimar Republic. The Bitcoin Foundation can't. They also can't just reach into your Bitcoin wallet and take money like they can from your bank account (think Cyprus.) The dream is that more and more firms start accpting payment in Bitcoin and that one day we'll be able to buy everything at the store with Bitcoins using a debit card or similar. It would also forever end the state control over money. The bubble component of Bitcoin was mainly due to Cyprus and is over with now. In case anyone's wondering, not having enough Bitcoins will never be an issue because you can transat with up to many decimal points.

1) Central banks print money to account for the expansion of the economy the money serve. Not so easy with a finite amount of currency.
2) A ponzi scheme is a scheme where early adopters rely on new entrants in the scheme to generate money. I don't see how you can consider the dollar to be a ponzi scheme. But clearly given the percentage of bitcoins owned by early adopters, and how the value per bitcoin grows with new adopters (because the amount of bitcoins doesn't scale, see 1), it can easily be considered as a Ponzi scheme.
3) Economics 101 might help some of the posters understand why we use money.

I am interested in digital currencies and mining of it.
What I have read/heard so far:- AMD GPU's are more efficient at mining than Nvidia GPU's (https://www.youtube.com/watch?v=EvhpOQHVZpM, https://en.bitcoin.it/wiki/Mining_Hardware_Comparison)
- LiteCoin mining is probably more interesting than BitCoin mining (http://www.hardcoreware.net/litecoin...ve-to-bitcoin/)
- for LiteCoin mining it is more important to have a fast memory
- LiteCoin mining is a bit more efficient with CPU mining, but GPU mining is probably still more worth it than CPU mining
My system has only DDR2 RAM at 800 MHz, but I suppose LiteCoin GPU mining depends much more on the GPU memory. If anyone knows it better, please tell me.Last edited by Fenrin; 12 April 2013, 06:19 AM.
