Not possible at all. Miner's electric cost alone is around $150-230, depending on geography location. So if the price dropped below that for long term, many miners will not be able to survive. And this will pose serious issue for Ethereum ecosystem.
I strongly believe $250 is the floor price for ETH currently. Until Casper (/Hybrid) launch, where the dynamics will go through major change and adjustment.
Miners are barely making a profit at the current prices. I know miners won't let the price drop any lower. With all the updates Ethereum has planned (casper, sharding, POS) it will reach a new all time high relatively soon.
I think OP is just one of those manipulators that tries to spread fud so he can buy in at a cheaper price.
