This quarter saw AMD not need to lower the MSRP of their graphics cards, and selling through as many of them as they could in North America due to the Bitcoin craze, that time is over. Due to China more or less outlawing Bitcoin and the resulting decrease in value due to the users realizing the currency was overvalued, the average bitcoin miner can no longer turn a profit with AMD produced graphics cards. This will reduce demand in the following quarter, but only a bit as non bitcoin miners are waiting to purchase their graphics cards. As for what this will mean for AMD, I don't know, but I feel it will have an impact and I think the author is remiss for not mentioning it. I'd love to know exactly what sort of impact it does have.
Hightech4us is not wrong, but Oh Homer is absolutely right, we desperately need an alternative to Intel. I say we need an alternative to Intel enough it may be worth seeing government funding for AMD and other alternatives.
Bitcoin will continue to be a somewhat useful means of moving money and making purchases as there are many who do not trust their governments money / want an alternative. Bitcoins principles are sound, but it's value will continue to fluctuate, an those who use bitcoin be warned it has a higher volitility than a Latin American countries currency in a financial crisis. I hold bitcoin and see a strong future for it.
