Interesting to me is the question of weather or not mining is still worth it, but without alot of context as to why people are mining in the first place. Because to me, either you are in it for some held beleifs or what not, or you are in it to make money as in treating it like a business. I think many miners that begin mining like the idea of making money, but have no idea how to treat it like a business. For example, for making money, asic's to me make sense, and those sense (cents...sorry couldn't resist) add up to dollars which any business needs coming in. If you are mining because of other loyal or crypto religious beliefs, then maybe it is worth it to those, but not so much to those who would like to run it as a home business, but don't know how...to those, maybe it would never be 'worth it'...I'm not saying I'm only ASIC, but I'll mine with whatever is still 'worth it'.
