Got a problem with the price?  Don't buy then.  It's that simple.  If demand slows down, then the price will likely drop int he future.  Stop your bitchen! 

Yes several members here have mentioned paying as low as 4c per Kwhr.  Crazy I know...

Also your pricing fails to mention that in some cities their is tiered pricing.  For example my friend pays about 12c per Kwhr for the first 10kwhrs per day.  Then about 15c for the next 5kwhrs.  Then it skyrockets to 29c after that.  Without the mining rigs he touches tier 3 every day just about, so its 29c per kwhr for mining rigs

About 30 hours and $3 in electricity. 

You are missing the fact that some people have free electricity, some pay just 3-4c per Kwhr, and others pay 30-50c!  I went in 50/50 with a friend on a 1G hash mining rig.  In the last 10 days it generated just over 3.5 BTC.  A lot of that was due to downtime from some of the pools out there.  The electricity cost at his place is 29c a Kwhr.  When we added profits up @ the current $14 ish per BTC.  In the last 10 days we basically broke even.  Needless to say, we stopped mining with this rig.  I will continue to mine with my 12c per Kwhr electricity, but im making only $9 a day with 1.4G hashes.

User error! 

I already had 1 desktop, so that kept my costs down.

Capital: ~$1100

M hashes: ~2000

One rig already had 1x 5830, just added a 2nd 5830 card @ $90.  Does about 580M hashes.

My 2nd rig I built from scratch.  It has 2x 5850's and 1x 5830 running off PCI-E 1x.  That rig cost me $600.  Does about 900M hashes

My 3rd rig my friend and I went 50/50 on.  It has 4x 5830's.  Cost us about $800, but we split the cost and hash rate.  So thats +$400 for about 550M hashes

In 2 months I paid for all hardware investment and put $600 in my pocket.

51% currently... 

Doesn't make economical sense to rent a mining rig even at his prices.

1Ghash for a little over $400 USD.  That will generate 0.66BTC a day @ the current difficulty level.

The next difficutly level will go up to about 1.6M or about 15% increase.  This will decrease profits to about 0.56 btc a day.

Lets be generous and assume a 10% difficulty increase every 10 days.

Say I bought a mining contract today, this is about how much at the most I can expect to make in a month:

1) Difficulty goes up to 1.6M in 4 days, so I'd make .66BTC @ 4 days = 2.64
2) 1.6M difficulty (.56 btc) x 10 days = 5.6
3) 1.76M difficulty (.5 btc) x 10 days = 5
4) 1.94M difficulty (.45 btc) x 6 days = 2.7

Total: 15.94 btc in 30 days.  Value according to current market prices: about 16 x 16 = $256 USD.  Net loss of about $150 per month.

Reason to buy a mining contract = 

I'm sure once opened up again, we'll see LOTS of trading activity, especially from those with free trades for a month!

49.97 here.  Thx.

Why do you post deals like this?  Are you trying to increase the difficulty level be encouraging new miners?

6990's are a terrible price / performance ratio card anyways.....

I'm looking forward to no fees @ mt gox for 1 month, because some of my transactions will be reversed because of the hacked account that lead to a crash.

I think it can take several hours even before your transaction is included in a block.

I've recently had a transactions take 12 hours to get like 6 confirmations....

Stop loving mining... It will take you a LONG LONG LONG time to pay back a 3x or 4x 6990 water cooled rig.  Those cards are EXPENSIVE.

Take a look at the current difficulty level... over 1.3M...

Compare tradhills volume with Mt gox.  Mt gox was doing 30K minimum per day and 200-300K on a very active day.

Tradehill is at like 7k for the day... their most active day.  Trade hill is still tiny in comparison.

I think people are anticipating that when Mt gox opens, trading will begin @ 17.5, so thats where the price is headed at trade hill.

Old news... its been up for the whole day so far...... 

Yea totally not cool.  I'm shocked that the network is growing at this rate considering the drop in coin prices + mt gox has been down.......  INSANE!

The video is horse shit!  Please report the video to youtube (already flagged it) so they can take it down!

6 blocks an hour is how the network adjusts the difficulty level.  More than 6 blocks in an hour and the difficulty level will go up, less than 6 blocks and it will go down.

Currently we are at 10.88 blocks an hour average!  Get ready for a huge difficulty level increase to ~1.3M!
