No exactly true. Depends on the price of electricity and other factors which are dependent on where you are in the world.
Hes not right. All these thingsthat has to do with making of profit and not making of profit are based on the expenses you make while working as a Bitcoin miner. When your loss are bigger than the profit youre making, then Bitcoin mining is not meant for you. Expenses you make depends on where youre living, the cost of electricity and other stuffs. But I still believe that Bitcoin mining gives more profit when the price is very low. But whatever
Im not a miner anyway.
