The most efficient miners will set the profitability, im afraid the most profitable miners right now are those who dont pay for electricity, the kids in their parents basements or at their companies or whereever no one cares. The rest of you who pay for electricity and/or maintenance will soon cease to be profitable. good thing i dont have to pay for electricity or maintenance, my mining rig is infinitely profitable right now.
Picture you describe will take place in FEW weeks, with current algorithm. So only the pilferers of electricity power will be frofitable in FEW weeks. Now there are some 10 000 miners, how much pilferers will remain? 1 000 ?!
LOL. "secure currency" being mined by .. 1000 pilferers world-wide.))))
People, wake up!
