I pay my electricity bill with sell a coin. it's already planned, a half a profit to buy new hardware for build new RIG and the rest I keep in the form of coin.
I just keep the coins and use the fiat to pay for the electricity. That is similar to buying coins.
I respectfully disagree. It is absolutely not the same, as far as I'm aware. The electricity costs and other costs for my S9 means that I pay about $2,500 for 1BTC with mining, while it trades for $11,000. So if I'm converting $2,500 to $11,000 (or on a smaller scale $250 in costs to $1,100) how is that the same as buying coin at $11,000?
