on the "GPU will never die" thread...
...I get LTC diff going up and up, more gpus for sure, maybe racks of gridseeds coming online too. Either way I don't see it going down much anymore, and profitability is getting really squeezed..
...then the non-scrypt coins should be getting hash, and diff going up, price going up. long term value etc. But take VTC, it's tanking like everything else EXCEPT LTC and BTC.
My hunch is actually that it isn't the miners that drive the price of LTC and BTC anymore (note new chinese LTC exchange..) and the link to difficulty has largely been removed, because now people, non-miners, actually buy the stuff. It is remarkable how solid the BTC price has been through the recent catastophes and continual diff increases. LTC is seen as early BTC by outsiders now, and the diff hikes are due to asics. The two things are NOT linked..
My point is no-one actually cares how "good" coin is, ie algorithm, confirms etc, the market decides. The crapcoins will die (switching pools thankfully have maimed them) and we will be left with a few coins everybody has heard of and form the future.
So I think GPUs are dying for mining, mainly because things like VTC are just regarded as another crap coin, which is unfair to the coin from a mining point of view, and asics are here from scrypt and sha256.
