I'm so sorry guys, but is this forum just full of a bunch of illiterate fools?
If you read anything in this post, read the big bold line.So this means miners are stupid? :p
Nah, just you.
That aggressive tone is unwarranted - stopping from mining when you still earn enough to pay the electricity bill is a bad business decision. If you can't comprehend this simple fact then there's really nothing to talk about. I thought you were implying that the whole notion of sunk cost is a fallacy.
If short run marginal cost is below what you can sell for, you produce more. You hope to recover your "sunk" cost over the life of the project.
God, I wish my tone was unwarranted, but it sometimes reminds people to go back and
read the OP. Clearly not in
any of your cases. Maybe I can help you with that. Just read the bold bits:
It's no longer profitable to invest in new mining rigs. [Under this assumption], why isn't mining stopping?
And my response:
If things stay the same, it will.
In other words, it doesn't make sense to mine if you are losing money doing it. Yes! That's what I said! And I only had to read the OP once! I bet you can figure out what this all means, Patrick? Well, let me help you along: If the short run marginal cost is
above what you can sell it for, we will be seeing a difficulty drop. Indeed!
Buying and paying off a card in this climate looks very tough and cannot be advised. However, if you already have the hardware and you aren't so worried about hardware deterioration then mining is surely still quite profitable.
My miner is still (price = 4.8 USD, difficulty = 1755425) just about beats electricity and not only do I pay the equivalent of about .17 USD for each kWh of electricity but my dual 5850 miner is currently housing an AMD Phenom II x6 1100T: overvolted, overclocked to 4.0 GHz, and running at 100% on all cores.
Perhaps some people have much higher electricity costs or are still trying to mine with Nvidia cards but I'd imagine the bulk of the miners are comfortably covering their electricity costs with their earnings.
Thanks for actually participating, Teukon. No sarcasm at all.
