Looks like the difficulty does not care about the price anymore. Price is close to 200, but difficulty jump a few minutes ago is 7%+.
Well, an industrial miner using widely available gear (0.5W per GH/s) and only paying $0.05 per kWh means they'll be profitable (at this difficulty) until the Bitcoin price drops to ~$53 ...or until difficulty increases to 167,638,063,430 (@ $200 per Bitcoin).
So, unfortunately for us home miners, there's room for movement.
But a home miner or anyone that uses an electric spaceheater like this one below
beats a farm since the spaceheater is essentially free power for a miner.
My wife used spaceheaters for years. 900 watt setting. So an avalon 4.1 is dead quiet and 2 of them use 960 watt slightly under clocked. No farm competes with that since power = 0.
Once room is warm turn the miner off same as a space heater. So if you have avalon 4.1's underclock them and use them as space heaters you can mine for years with them.
A lot of complex shit will happen as miners fight over the coins.
