Morgan Stanley say bitcoin mining only profitable above 8600 dollars. I'm not sure this is correct though, especially if future valuations come anywhere close to fruition.
Bitcoin mining profitability only based on the electricity cost,if his country has the high electricity bill then he may can only have profits above the price what he mention but in some countries the cost is very cheaper so they can make profits even the price is lower.But that is not the stable price of bitcoin soon it may go to moon so keep mining the bitcoins and hold them.
