With the price plummeting I am wondering at what price will Bitcoin not be profitable to mine anymore? What is the break-even point?
What happens when the price is so low that it costs the miners more to mine BTC than it rewards them? What happens if they pull the plug? BTC is dead then?
Mining stops as soon a Russia, China, North Korea and the US set off all their nuclear bombs on the same day. Then, all the miners are completely fucked and they will stop altogether.
