Unless the price of BTC goes up soon, it doesn't make much sense for hardware manufacturers to design and manufacturer more efficient hardware, and it also doesn't make much sense for miners to buy more efficient hardware.
I doubt we'll see much money invested in new mining hardware after the first half of 2015 unless the price of BTC spikes.
At some point, even the biggest Bitcoin bulls need to face reality and pay the bills.
impossible is to Bitcoin price spikes,because miner must sale all BTC to pay electric bill and bay new gear.Also manufacture must sale all bitcoin to pay chip maker.
and price is now good 230-250$ for 1 BTC is good price.
Also be good if BTC drop 100-130$ or lower because all big miner go bankrupcy,and hardware manufacture closed door for 30-60 days,and bitcoin return to home miner
and i bay BTC for low price and wait next halving.I have money in saving acount whit 0,25% interest.If bitcoin jumpe in one year 5% i am on horse
