        in 5 years:   1 BTC=$60 (USD)

If Bitcoin is still around 5 years from now, it will be much higher than that.  Otherwise it will be much lower than it is today.

I need to pm someone, how can i ?

Looks like you can now.

- You must have made one post in order to send PMs.

[...]
Note that it may take up to 10 minutes for your PM or posting permissions to be granted. (The system automatically checks every 10 minutes and promotes people as appropriate.)
3723  Economy / Currency exchange / Re: How does mtgox compare to bank conversion? on: October 08, 2012, 08:52:15 PM
I have the need to occasionally transfer some funds from GBP. I have been having the bank do it but have been seeing large chunks of money disappear in fees (and what I guess is a less-than-market exchange rate).

Mt. Gox' has wallets for nearly two dozen currencies.  If you transfer GBPs to Mt. Gox's bank, it will be added to your GBP wallet with them.  The only amount subtracted are the wire fees.  If you instead have your bank convert the fund to USD and then transfer, then yes, you would lose from the GBP -> USD conversion.

 - https://mtgox.com/press_release_20120815.html

Obviously, the transfer is into different currencies and GBP->BTC->USD seems like it definitely wouldn't be worth the bother but I'm thinking I might be willing to hold some BTC for a while and see if it doesn't become easier to spend them directly.

If you simply want to go from GBP to USD, there are other services that might do that more efficiently for now:

 - http://www.CurrencyFair.com
 - http://www.TransferWise.com  <-- Not USD yet, but to EUR, etc.

Other methods available in the UK:

You can send cash (GBP) in the mail to Bitcoin Nordic (in Denmark):
 - http://www.BitcoinNordic.com


And, or course, there may be a chance for a local trade:
 - http://www.LocalBitcoins.com


Also, BitInstant now has an online bank transfer methods which supports a couple dozen countries, including the UK:
 - http://www.BitInstant.com

For Bitcoin in the UK, BitInstant just released an online bank transfer system. This has not been publicly announced yet, but it works, and is very fast.  

On BitInstant.com, select your UK flag (You can see many other countries are available for this as well), then select Online Bank Transfer and go through the process. You can have the funds converted automatically into BTC and sent to your Bitcoin account, so you don't even need to bother with any exchanges. Fee is 3.49% if over $100 worth, and 3.99% if under.

EDIT: note that these bank transfer payments are nearly instant (matter of minutes). It does not take 1-3 days like most bank transfers. It's pretty baller, actually

BlockChain.info now accepts funds from Barclays Pingit:

how good a quality do these things need to be?

They probably use software that can tell a photoshop job regardless of the quality so as long as it is readable you are probably ok.  I had a problem with a cheap phone that wouldn't focus well, so the only way it was readable was if I held the phone far enough away so that it would focus but then the ID wasn't even large enough to fill a quarter of the pic.  It passed anyway.

Can you use a drivers license and a car insurance card?

Probably.   If not, they will let you know.  But once you start AML, you might not be able to do any trading or withdraws until successfully verified.

When I get my wallet to sync will I still receive these or did I lose them now? :/

You don't actuallly receive coins.  The software just doesn't know what to show for your balance until it has caught up on the blocks.   The wallet is only needed to spend the coins.  As long as you have your wallet.dat you can spend any payments received to those addresses.

2x 7970s, 6870 and a 2 nvidias (the nvidias only do very little)

If you have NVidias, keep this in mind.  CoinLab is building a GPU client that prefers NVidia for computational work.  But your mining today on their pool with your AMDs gets you loyalty points for use later when GPU mining gets unprofitable.


We're planning for the first version of our custom client to be ready by 11/1.

how are odds calculated on bets of bitcoin??

Winning bets get 90% of losing bets.  So if winners had 8 BTC wagered and losers had 2BTC, there would be 1.8 BTC distributed to those that had bet the 8 BTC.   The amount earned will depend on when the bets were made.  Earlier bets are weighted much more heavily than bets made right before the bell.

P.S. I got a Dell l702x with a geforce 555 m 3gb and an i7-2670qm... will it do anything worthy?

That card is weak sauce, sorry.

GPU mining is just about at the end of its run anyway, so it probably wouldn't be worth your effort even if it was a halfway decent bit of mining hardware like a $100 AMD 58xx card.

I prefer money pak but apparently it is reversible which i didnt know.  please get back to  me with a method  that  would work for you.  reputable sellers only

Cash works, at a lot of places. 

Including trading with someone local:

 - http://www.LocalBitcoins.com


and cash works well for deposit:

 - http://www.BitInstant.com (Deposit at major banks, 7-11, Walmart, CVS, Moneygram, etc.,)
 - http://www.BitMe.com (Deposit cash at Chase)
 - http://www.BitFloor.com (Deposit cash at Chase or Wells Fargo)
 - http://www.MrBitcoins.com (Deposit at a bank in U.S., India, Australia)
 - http://www.CAVirtEx.com (Deposit cash at several banks)
 - http://www.Spendbitcoins.com (Deposit cash at a bank in Australia)
 - http://BitcoinNordic.com (Purchase CashU or UKash in dozens of countries)
 - http://www.BTC-E.com (Deposit cash (USD) at bank locations in Russia)
 - http://www.BitNZ.om (Deposit cash (NZD) at back locations in New Zealand)
 - http://www.BitInstant.com (Deposit cash in Brazil using Boleto or Banco Recomendito, or in Russia, using Qiwi or Cyberplat.)

Also, Bitcoins Direct will accept cash, but they have a $500 minimum order size:
 - http://bitcointalk.org/index.php?topic=87094.0 (Deposit cash at Bank of America, Wells Fargo or PNC, minimum $500)

3732  Economy / Service Discussion / Re: lost blockchain.info wallet identifier on: October 08, 2012, 08:37:50 AM
emailed wallet@blockchain.info for assistance, but haven't heard back in a week.

The operator of BlockChain.info had been traveling for a couple weeks until this past weekend.  Be patient, and then maybe try again if you don't hear anything for a couple days.


We still have the password - but can't find the wallet.  (user deleted all his apps for some reason..)

Should info on a transaction theoretically be enough for piuk to identify the wallet and supply the ID?

Most likely.

Once access to the account is regained, there are several protections going forward.  Of course, adding a bookmark with the URL for the wallet is good.  Also setting up an alias is something that is useful.  But configuring the account with an e-mail address and having backups sent there automatically with each change to the wallet is likely a good further step.

3735  Bitcoin / Development & Technical Discussion / Re: Double-spending with 6 confirmations on: October 08, 2012, 05:20:42 AM
Well... Seems to me there is no a 100% solution to the problem.

As always, the level of security needed should be proportionate to the risk.

If a merchant is going to run their own node, there are two recommendations:  Disable incoming transactions, and have an explicit connection to a well known, trusted node. 

That's the recommendation for the merchant selling donuts.

For a merchant that has a higher volume (.e.g, ecommerce site or exchange, etc with larger volumes), it would be prudent to have listening nodes to confirm that your longest chain is the same as the rest of the world's longest chain.

There are situations where bitcoin is not an appropriate payment method.  Accepting Bitcoin payments requires relatively continuous network communications:
 - http://bitcointalk.org/index.php?topic=106302.0

Certainly though, with there existing these attack vectors, there will be poorly configured merchants out there and there will be thefts on merchants accepting payment with 0/unconfirmed.

But to see losses on confirmed transactions would only occur if you didn't follow the basic recommendations.
3736  Other / Beginners & Help / Re: Mining profitably on: October 08, 2012, 03:47:51 AM
TL;DR If you consider mining, forget about BTC price and its future. You need to amortize your BTC investment in 2 months with the BTC you generate by mining, taking into account the ever-increasing difficulty. If this does not pay off, you better purchase BTC and forget mining.

Until there is another use for ASIC hardware should mining with it no longer is profitable for mining, that is nearly the exact conclusion I come to as well.   With GPUs, you can always liquidate the hardware for use in gaming or to other miners whose cost of electricity is significantly less.  What will likely happen is that the only market for a used ASIC will come from a miner with really cheap (or free electricity).

But any miner roughly breaking even in two or three months then can mine until profitability drops near zero or goes negative for them.  There is zero risk after break-even, and potentially, there is a huge upside of continued fantastically profitable mining for many more months if delivery estimates ended up being too high (which is entirely possible if shipments only slowly leak out, especially if the block reward drop sends most GPU mining to pasture).

Just like BFL's announcement in June put a damper on competing FPGA manufacturers, there very well could be some innovation that will slow demand for more of the first generation of ASIC miners.  [Edit: Like what would happen if this suggestion to increase the Nonce size were to end up on the schedule:
 - http://bitcointalk.org/index.php?topic=89278.msg1250067#msg1250067 ]

So between the uncertainty about when these ASIC ship, what volume of hashing power ships, future price of hashing power, and the future BTC/USD exchange rate, there's no guarantees whatsoever here.  Who thought mining would become a bigger risk than investing in coins even?

Ah ... I see why every single BetsOfBitco..in e-mail ends up in my spam folder.


I've noticed that gmail is particularly insistent that all messages from bets@betsofbitco.in get placed in my spam folder.  I "train" the filter by marking them "not spam", but the .in force is too strong or something else is causing it to remain flagged as spam.

Setting up SPF on your DNS might help the spam algorithm to more correctly identify the legitimacy of the message.


I'll look into SPF.


$ dig  @ns-canada.topdns.com betsofbitco.in txt

gives:

;; ANSWER SECTION:
betsofbitco.in.      3600   IN   TXT   "v=spf1 a -all"


And because I have a spam filter service that relays messages to me, that filter rule will always cause a hard-fail.

If you change that to softfail, ... "~all" instead of "-all", then my spam filter can at least be sane.

I see others recommend softfail as being recommended for when the mail destinations (recipients) are not under a company-controlled set.  Here's one recommendation affirming softfail as being less draconian:

How hard would it be to build an electronic device that could generate and display a Bitcoin public / private key pair?  It would be nice to have a physical device that could, without connecting to anything, give you a new safe address to dump your coins to at the press of a button.
