Even if you're below the point of breaking even, you're still getting discount coins. If coins are trading for $8, and it costs you $4 per coin to mine them, you're still getting coins at 50% off their cost.
If it costs $4 to produce them and they're trading for $8 you're hardly below break even.
You can do more than one thing at a time can't you? I'm simply saying that it isn't very bright to base your long term operation on short term prices. That isn't sustainable.
Sure you can, but that would only make it slightly less idiotic. There is no way your long term bitcoin speculation can benefit from getting fewer bitcoins than possible in the short term.
