Come on comeonalready... I didn;t know you to be such a doomsday announcer... If I had a penny for all the bad predictions I heard over the years I would crawl under my rock and be a filthy rich lizzard.
I've been mining since late 2012. I've mined for nothing, I broke 14 GPU's, I've mined at a loss, I've mined with great profits and every time ppl kept saying how the end of the cryptoworld is near and we should all quit. For some, THIS is not a game. If you want to gain enough then you have to stick with the plan and do your homeworks. The market is flooded with Sunday miners and ppl who just want to get rich fast without even understanding what the hell they are doing. They will be the first to go and unfortunately because of all the hype and late jumpers, altcoins with never recover but what the hell, we keep on mining. And as I said before many times, ASICS will not scare hardcore miners, we'll just have to find something else to play with our rigs.
Bottom line is, this is not and will not be the end of GPU rigs. But if you feel like selling then I'm definitely buying.
I agree with you, cryptoworld ends when miners leave it, until then there will be always something to mine with gpu. If it wasn't, we would make one !
For now, please take a look at Vertcoin (VTC) for mining with your rigs.
