Those of you welcoming GPU mining for LTC/SC have kinda missed the point of why those currently hold the #2/#3 spot in the cryptocurrency world...
haven't you realized, that sc is just cpu AND gpu-minable?
yeah, i mined sc2 with my cpu's, then the reaper came up and i mined with cpu AND gpu...
first the sc-gpu-mining was more profitable compared to btc, but this lasted not very long and i went back from sc-gpu-mining to btc-gpu-mining...
some
"enthusiasts" stayed on to gpu-mine the unprofitable currency...
...others may call them
"informed insider" atm sc-mining is totally wasting energy, if you have to pay for power...
whats your problem now with public ltc-gpu-mining?
the best paradigm - cpu- + gpu-mining - for ltc is sc...
atm its profitable to mine ltc with gpu's, but diff will go up quickly and the gpu-profit is away...
the problem i see is the efficiency:
sc: cpu is slightly more efficient then gpu
ltc: gpu is more efficient then cpu
factor 2:1 is realistic for mining-rigs, where you have to count only the extra-watt of cpu-ltc-mining in comparison to gpu-ltc-mining/complete rig
when many "ltc-gpu's" go back to btc, then there is a very high diff (respectively low price) and the cpu-mining is very unprofitable, we have seen this with tbx and fbx, nearly noone is mining them...
the conclusion is to switch to the sc2-algo or we find a better gpu-hostile-algo...
but how long will it last up to a talented programmer, who will find a way to gpu-mine the new algo more efficiently then cpu...
then we are back at the starting point...
