What's the average cost to mine a coin now, kindly tell me, guys.
On average it costs around 1 BTC to mine a bitcoin -- less for some, more for others.
It should never cost more then 1 BTC for someone to mine 1 BTC. If it does then the miner is essentially giving away money to the electric company. This miner would be better off buying bitcoin on an exchange if they wanted to acquire additional bitcoin
