Who says miners are losing money? Any proof of that? Once they've bought their ASICs, electricity's cost is very low. They are making less money, that's right, but there's no sign any miner is actually losing money from its daily operation.
Very simple calculation: Electricity per month: 21'000.
Coins per month: 78
Price per coin: 200
Revenue: 15600
Loss: 5400
Price per coin: 300
Revenue: 23400
Profit: 2400
So why should I accumulate a monthly loss of 5400 at the moment?
And just as a reminder: The costs for the hardware and maintanance is NOT included here...
