Ah, my mistake. I see now what you mean. I think anything priced in BTC is going to HAVE to drop in price as the difficulty goes up, regardless of price. People paid xBTC, and they want xBTC mined in return. Anything priced in USD only has to drop if the BTC price remains the same. If the BTC price goes up, they can keep the USD sale value the same. People paid zUSD, and they want zUSD mined in return.
Next year you will need ASIC hardware that's $10 per GH/s or less, nothing that cheap on the horizon. It's the energy, Internet, housing, and interest expenses that need to be covered before you start getting any ROI on the hardware. If you could pay the expenses with BTC the story would be better.
I laugh at Block Erupters, even at .35BTC that's about $100 per GH/s making them the most expensive ASIC around. And people still buy the things in droves! Just shows you the lack of smarts in the BTC mining community.
Only if you dont know how to mine enough with it. It looks besides merged mining there are uncommon coins that can turn the field. At least i know a member that buys AM-Miner for that reason.
