I was looking at my mining history and saw that I was making 0.1 btc every 20 days (or 0.15 per month) when I shut down. The price of bitcoin back then was about 80 dollars each. So, I was making about $10 per month running the miners and I was paying $200 for electricity.

Little did I know that bitcoin would go past $8,000
Either way, I could not pay that much for electric month after month while waiting for the price to make it profitable.
