With an existing 5850 GPU and summer air conditioning, it is costing me ~$0.80/day to mine (total rig wattage). (~$5.60/week)

At the current difficulty, I earn ~0.1BTC/week which is currently ~$12/week.

That makes for a profit margin of ~100+% and is significantly cheaper than purchasing BTC directly with that ~$5.60/week.

At the current difficulty, it would be profitable for me to mine even with the price all the way down at $60/BTC.

And in wintertime even lower - noted that the equipment is already paid off.

I think difficulty of Bitcoin goes very high. Mining is not profitable now. Without miners coin will be dead.

Do you think it's the time to adjust difficulty?

Share your opinion.......

Difficulty is a function of how interesting BTC is to mine. The more miners the harder it becomes. If there were less miners, difficulty would be lower.

Actually its a function of relative luck in a sliding window. If we keep getting lucky, and blocks are found faster or slower than a certain rate, the difficulty changes. If we get lucky, we could see a change, if we start getting unlucky, we could see a change the other way.

Miners who can figure out how to get more lucky (like by increasing hashrate with various designer chips) gets more of the future block rewards. And later on, someone will be fragging aliens in doom with all the GPU miners in electronics recycling heaven.

I think you are going to see a lot of GPU miners shutting down or moving their rigs over to alt coins anyway once ASIC's really take over hashing. We may even see a temporary difficulty drop.

We have Moore's Law on our side (as miners).

Electricity Cost

How do you calculate electricity cost? I thought it was different depending on location.

As it states at the bottom of the page:

* Electricity consumption is estimated based on power consumption of 650 Watts per gigahash and electricity price of 15 cent per kilowatt hour. In reality some miners will be more or less efficient.

no, you are thinking wrong
if you are only planning on mining and selling right away to a fiat currency you may be correct
however, you fail to take into account the rise in real value of a bitcoin in the future as well as ignoring the exchange rates
the only time you would ever stop mining is if it's cheaper to just buy it from someone else at current value

Just stop mining, so the difficulty will go down and it will be more profitable for me. Grin
