I missed the Bitcoin boat, even though I new about it in 2011, I didn't pay much attention to it. Bought a couple of coins at a peak, thinking of mining now. I found a chinese company selling 100 GH/s asics at a relatively cheap price but they will ship only in february. By that time there is a possibility that even 100 GH/s will be useless. So I wanted to ask if that would be the case or is it still worth buying asics?. I can't afford those ASICs that have > 1 TH/s though they might be cheaper on a per giga hash basis.
