Ok somebody help me out on this.
I see ASICs listed everywhere, prices are absolutely ridiculous. Any BTC calculator shows that they will never ROI. And the explanation that I keep finding is that if BTC price keeps rising, it will all be worth it.
Here's a pretty active thread:

People can't wait to buy this 200Gh/s  miner for £2,800.

Somebody PLEASE explain why?? And how??
