Is mining profitable at say bitcoin price below $400US , i would say no , anyone think it is.

I don't know but I think the drop will shake out a few small miners, - leaving the field to the big few.

Big Miners

While individuals give up prospecting, at least two other larger mining companies, KnCMiner and Cloud Hashing,(MEJ) are still generating profits. By scaling up operations, they’ve been able to save costs on cooling and power, making their computers more efficient and cost-effective.

KnCMiner, based in Stockholm, operates about 7,000 machines. While the mining company’s electric bill in March came to $450,000, the computers mined 21,000 bitcoins, according to co-founder Sam Cole.

Cloud Hashing, which lets people buy computing capacity in its data center and share in profits, mines about $230,000 to $260,000 worth of bitcoins a day, according to Chief Executive Officer Emmanuel Abiodun.

“We are profitable whether we sell contracts or not -- through mining,” Abiodun said in an interview. “Our business model can handle volatility in pricing.”

So there you have it, from the CEO of MEJ.
