I don't know that I would trust the sell advice of someone named "bitcoinbear"! I'm not selling my bitcoins too eagerly (unless I'm making points on the sale).

The problem is trust: BTC is indisputable and irrevocable - once you have sent them, they are gone. The same goes for sticking cash in an envelope and mailing it to someone. (The same goes for wiring money to an exchange too, while exchanges have been mostly trustworthy, what about they day they just disappear?) You have to trust the recipient will fulfill their end of the bargain when you don't have any authority to complain to.

You can look at http://bitcoin-otc.com/ to see the reputation of independent buyers, which is as good as it gets if you don't want to be there in person to exchange money and don't want to use an exchange.

The buy price of the BTC was $13.21. As you can see, there were a few opportunities to sell for profit after the purchase, but the price hasn't been there since July:


Also the OP posted about the purchase June 19, and last logged on June 21. Looks like they weren't interested too long...

Any overvalued eBay auctions were probably fraudulent non-paying joke bidders or bidders that were planning on reversing the PayPal payment after they got their BTC.

You can also click on the user account, and look at their last posts and how long ago they logged in. The user posting the video card for sale last posted to the forum in June - most likely the card is no longer for sale and the user is not an active participant on the forums.

Besides the GPU fan, you also need adequate case cooling - putting 200 watts of heat into your computer case is not a good idea unless you have the case fans to remove it. A couple 120mm fans are probably the minimum.

It sounds like what your are attempting to do is solo mine, which is completely impractical unless you have racks of mining servers.

What you will want to to is join a mining pool. Here is an explanation of how one works. You set up a user account on the pool, set up individual miner logins for your miner, and use those credentials in your mining software to connect. After you have earned Bitcoins, you can have them sent to your wallet address.

Bitcoin is completely unrelated to mining software. If you are having a problem with guiminer, one problem some users have had is that the program opens off-screen so you can't see it.

None of this matters if you don't have a high-end ATI video card to mine with - anything else is a waste of electricity.

Clearly when we say noobs should search before posting, there is a limit...

Maybe this will be a "oh, I guess I should look at the date first" learning experience?

If you have 50BTC in one address, and spend 1BTC of it, the remaining unspent currency does not stay at that address, it gets sent to a new generated address in your wallet. This is to enhance anonymity. Although you still have the coins, it looks like you sent them. A transaction would look like:

2010-12-25:
 Generate 50 BTC -> address Wallet1

2011-09-25:
Input 50 BTC from address Wallet1 ->
 Output 1 BTC -> recipient
 Output 49 BTC -> Wallet2

So the coins were unmoved for nine months, and although only 1 BTC was actually spent on 9-25, all of them were sent to new addresses.

Figured we could use some bullish news.

Bitcoin still up 75x in exchange price in a year, does anything else do this?

Here's a graph of the September 2010:
Bitcoins for six cents!

See the purchase of 10,000 BTC for $610? That's now $46,000 if I simply click sell even at today's market low. Too bad that wasn't you...


Here is the current week's price:


See a couple 5k sales profit-taking in the last few days pushing the price down? How many more 10k BTC owners are out there? You could be one if you get in during the dip!

That's good until I am out of Bitcoins. Then I need to earn some more by selling goods and services. Then I can spend those on other goods and services.

Saving is not hoarding. One of the problems with many economies is the low personal savings rate (pdf).

Mining activity simply makes the blockchain harder to attack by making a cryptographically strong problem. Bitcoin still works fine with 1% of the current hash rate (as long as miners don't leave all at once.) As the difficulty would adjust to keep six blocks (and 300BTC generated) per hour, only a reasonable amount of hash power that would prevent the strongest anticipated attacker from forging blocks is necessary.

More mining makes it more expensive to generate Bitcoins. You can say that this makes the price be influenced by the amount of mining, but it is more that the mining hashpower is influenced by the price. If the exchange rate was five times the current price, mining activity would probably grow by a proportionate amount. Mining activity seems to have settled into the expected equilibrium, where miners are making barely more than their electricity bill. As a side effect, this also means that profitability sets the cryptographic strength of the blockchain.

That sounds like you sell at a constant rate - 100% of generated income, as fast as you generate it. You are just breaking your sale into quantums by selling only every day or every week; 100 other people like you and there is a constant flow of new BTC into the economy.

Speculation, investment, and optimism that the price will increase will increase holdings by miners of their generated income for the future, and that will further affect the market value. By liquidating as fast as you generate, it just doesn't sound like you are very optimistic.

http://dot-bit.org/HowToBrowseBitDomains

The biggest hurdle is that domains can't be used without a browser plug-in or DNS modifications. There are probably less than 1000 (less than 100?) people that have actually set up .bit addresses to work. While the name can never be confiscated by the federales, it's pretty much useless anyway, as nobody can get to your domain without configuration (and it won't show up in search engines either). It's significantly easier to just bookmark an IP address.

Zalman near-silent GPU cooling with adjustable fan speed. All-copper with heat pipes.

I used this on my 9800GTX to great silent effect. On a 175W 5830 the temps run away higher than the loud stock cooler, but it should be good on a lower wattage card (if your card only uses one PCI-E power connector, etc). Includes just enough thermal grease for one last use. The little ram heatsinks were used, so their double-sided sticky tape is no longer sticky.

Edit your post and use the BBcode [img width=300 height=400] (or vice-versa for the landscape pictures). They will still be large, but will be resized by browsers.

It looks like you have two 5830s with full size display port (SAPPHIRE 100297-2L, small box) and three 5830s with mini display port (SAPPHIRE 100297-L, big box). Please confirm that is correct and specify which you are sending to buyers.

It's not my pool, I just mine there and find it good enough to recommend.

mineco uses PPLNS (pay-per-last-N-shares), a payment system where the work submitted in the last 12 hours or so is considered when splitting rewards when a block is found - on average every 24 hours at the current hashrate (without getting technical).

Slush uses a round system where only work you have done since the last block was found is considered, and it uses a formula where older work is valued less. The formula isn't good enough to make it completely hopper-proof though, the fee is 2% and they keep the earned transaction fees. They have a higher hashrate, so you get more frequent smaller payments.

ozco sounds like a deal if they are going to pay out 55BTC per round for the next several rounds though.

Here is a comparison of mining pools.

...and never do this again.

Yes, there are. There are a few that even pay the transaction fees earned out to miners, so you make the same estimated rewards as if you were mining solo. See my sig.

The 5870 is the only card worth mining on, the others will use more power than the BTC they generate.

400Mhash/s from that card:

~0.23 BTC per day pool mining at current difficulty; $1.23 at current exchange rate.
or
a 50% chance of getting 50BTC after 7.25 months of mining

I sure hope that is ESD carpet...
