November Bitcoin mining update:
At $105,780 per BTC, my 26 machines are making $4,725 a month now (0.044718 BTC)
It costs $3,636 a month to keep them operating (hosting/electric), for a profit of $1,089/month.
To date, I've stacked 3.77 BTC worth $401,082 and will continue to stack.
I've spent $135k on my machines over a period of 3yrs. I've spent about $74k on hosting/electricity in that same period.
I've averaged $9.6k a month in revenue. I mined more BTC early on when the difficulty was lower, but so was the price of Bitcoin.
I employ a mine and hold strategy to increase my overall performance.
