It's winter. That means we have to use heat. So, rather than running the electric base-board heaters, I'll run my BTC miner. Even if it breaks even, it's still better than having to pay for heat.
If you are unfortunate to have electric heat I guess that is true. For those of us with natural gas heaters, using miners as heat would cost more.
I just did a calculation based on current price of $12.31
Mining profitability (my rigs) per day: $5.29
Cost of whole house per day electricity (most recent bill): $4.86
Cost of mining rigs (which help to heat now): $3.44
So it appears bitcoin would still pay my electric bill plus about $10/mo and reduce my gas bill somewhat. Not enough to keep $1200 worth of GPUs unsold.
I'll give the coin price a few days to rise. If it doesn't, shutting down. In reality, with ASICs right around the corner, its either shut down today or what, shutdown in a month or so?
