Hi guys i need to purchase only 1 BTC. I've got a wallet and setup at block chain and need only the 1 BTC to complete a purchase for a subscription that has expired. If anyone can sell me 1 BTC and transfer it to my address i'll be so happy it'll feel like Christmas...  Grin

You didn't mention what payment methods you can offer.

e.g., PayPal, Dwolla, etc.
2723  Other / Beginners & Help / Re: Turnaround time on: December 11, 2012, 09:01:26 AM
Its best to wait for at least one confirmation.

Especially because the transaction you received itself might not be confirmed.  This can cause a problem if you pay someone else and then you find out that the transaction to you was a double spend after you've already paid.

Or if you are sending the funds to something like SatoshiDICE -- you might think you won, but until the transaction confirms your payouts won't confirm either.
2724  Other / Beginners & Help / Re: Accepting BTC on my website on: December 11, 2012, 08:20:40 AM
Not a new wallet, but a new bitcoin ID, or payment address within the same wallet, is recommended to keep track of payments from different buyers.

Yes.  CoinDL.com was created with this, for instance.

I do not want to use google authenticator, and I don't want to have to buy Mt. Gox's yubi key.  

I believe you program the Yubikey OTP with the secret from Mt. Gox, just like you would configure Google Authenticator.

2728  Bitcoin / Mining speculation / Re: On the contrary, its actually good ASICs are coming when they are... on: December 11, 2012, 05:26:29 AM
I'ld like to see that calculation (or I'ld be happy to run the numbers myself.)

What is your cost of electricity per kWh?  What hardware (e.g., what GPUs specifically)?

10.5c/kwh  .. 3300mh @ 1120watts

You are producing 3.3 Ghash/s and only consuming 1,120W?  That's atypical, at best.


I mine w/ just GPU's

Not just any old GPUs, and not without a lot of tweaking to get those numbers, I suspect.

Well, congrats -- you get about another 8 BTC worth of profit for the the next month before this happens:

If the foundry keeps up 4 layers a week from now on, it means ASICMINEr should receive the chips just before Christmas, so we could theoretically (hopefully) have something online before the end of the year....hashing the first ASIC mined block ever

then following that:

(~2-3 weeks)
First 6TH/s online
(~2-3 weeks)
Second 6TH/s online
(~0-4 weeks)
50TH/s of chips out
(~2-3 weeks, ~2-5 weeks if location changes)
Part or all of the 50TH/s online

Double dipping could only occur when product exists, it does not require any manufacturer take 51%, simply that they bring online their excess stock, to make money off both sales and unsold stock.

Not every ASIC manufacturer is selling hardware to customers.  From another thread:

Why not buy an FPGA or pre-order an ASIC?

You probably would want to read this thread first then:

2731  Economy / Trading Discussion / Re: Square's new account-to-account transfer ("Gift Cards") on: December 11, 2012, 04:21:44 AM
followed by a security shitstorm.

All the concerns about having a Bitcoin private key QR code exposed are kind of the same concerns someone printing out a Square gift card would have.   

So let's say I receive a $100 Square gift card to a grocery that uses Square Register.  So I print it out and go to the store and charge $15.

Then the next time I visit I scan it and it says $0 balance remaining.    Who suffers the loss?

I would suspect that Square would tell me I'm out of luck.    There is a difference in that the grocery would be able to tell where and when the remaining amount was spent. 

But it likely won't take long for thieves to probe the system and figure out how to take advantage of these weaknesses.
2732  Bitcoin / Bitcoin Discussion / Re: How would you like to design a bitcoin banknote? on: December 11, 2012, 04:14:05 AM
You kind of can't, but fortunately it is so expensive to get your own hologram that few are going to do it frivolously and without putting their name on them. Anonymous holograms are cheap there is no point in making a custom no name design.


Well, looks like bitcoin is no longer the only pioneer here.

"You can send a Square gift card to anyone with an email address. No smartphone? They can print out a QR code."

That's Square's Jack Dorsey:
 - https://twitter.com/jack/status/277824833130209280

I haven't seen a printout from Square with one of these gift cards, I'ld be curious to see one though.  (e.g., what size is the QR code).

But this paper QR code as a bearer instrument works because it is familiar -- it works kind of like cash [Edit: as long as the underlying electronic transaction can occur.]

2. Because of that, trading participants will try to "arbitrage" this fact and will move the price quite close to that value before trading stops.

And that's exactly what's happening.

So the BUH3 (March 15, 2013) BTC/USD futures are in la-la land at $16 and change:

While BUZ2 (December 15, 2012) is now within 1% of the Mt. Gox last / spot market price with just a few more trading days remaining.

Also, can check for JavaScript errors before sending that E-mail?

It very likely could be a browser incompatibility, and I'd like to get it fixed:)

Uncaught TypeError: Cannot call method 'play' of null

v.event.add.o.handle.ujquery-1.8.3.min.js:2


[Edit: The site was updated, this is resolved.]

can you E-mail admin@bitcoinvideopoker.com the URL to your account?

e-mail? Seriously?  

E-mail is a clear text transport method, and thus is not good for sending URLs which have the ability to claim and/or withdraw bitcoins.

What's your GPG key so that I can encrypt it first?
2736  Other / Beginners & Help / Re: Transaction change vanished on: December 11, 2012, 02:02:43 AM
Know how to do it?

There is no install.bat, it is a python script. 

So I'm assuming you are a Windows user then.

Windows doesn't come with Python installed, so you would need to install that in order to run the script.

 - http://www.python.org/ftp/python/2.7.2/python-2.7.2.msi


Then download pywallet  (right click and "Save Link As" or something like that):

 - https://raw.github.com/joric/pywallet/master/pywallet.py


Then to run the script from the command prompt it would be something like:
  C:\Temp>  python pywallet.py

Though if the python executable isn't in your path you would need to probably add it and re-open the command prompt so that it is in the path.  There is more info here:

Dumped all the backups of all the wallets looking for "1PyDNpaHGaAxazG13Xa7sESVeQbympLrHw", no luck. Last backup of wallet #2 (last before sending and loosing the BTC) has among other stuff the following worrisome contents:

Just to eliminate any remaining possibilities, have you tried extracting the keys for wallet #2 using pywallet, rather than with the bitcoin.org client?

Use

For him or for Bitcoin?

From another thread:

It looks like finally the point is getting across that Bitcoin can be useful no matter what the exchange rate.

That would be describing it as having intrinsic demand then, wouldn't it?  Cheesy

It has final demand, regardless of whether it is accepted for tax payment.

Maybe he now sees the source of value, where bitcoins simply aren''t "worthless credits on your computer".

This is quite a bit different take on Bitcoin from him since less than 60 days ago:
