2281  Bitcoin / Development & Technical Discussion / Re: SatoshiDice, lack of remedies, and poor ISP options are pushing me toward "Lite" on: January 01, 2013, 07:57:13 PM
We're not close to reaching the block size limit

You and I have differing opinions on what "close" is then.

Here are the last 10 blocks:

214657   48.711
214656   31.016
214655   133.286
214654   261.695
214653   15.265
214652   42.617
214651   36.039
214650   204.577
214649   3.489
214648   214.828

The average for these is about 100K.

And it appears to be approaching the rate of 300 transactions per block (about 43K transactions per-day). 
 - http://blockchain.info/charts/n-transactions-per-block?timespan=180days&daysAverageString=7

This is a transaction every two seconds.

A lot of these are microtransactions (e.g., under a dollar's worth of coins) used for wagering, so the blockchain already has a way of limiting those:

Quote
If the blocksize is more than 250 kB, transactions get increasingly more expensive as the blocksize approaches the limit of 500 kB. Sending a transaction when the blocksize is 400 kB will cost 5 times the normal amount; sending when it's 499 kB will cost 500x, etc.
- http://en.bitcoin.it/wiki/Transaction_fees

But twelve months ago no SatoshiDICE existed and nobody knows what 2013's breakaway Bitcoin success story will be but what if there are four of them, each as popular as SatoshiDICE is today.    Then the blockchain size limit (at the current restrictions) will be reached.

It looks like the Reference market was active on Dec 31st (until 17:14) and the event date was Dec. 31, 2012 end of day Eastern Time. Was it known? Huh

http://betsofbitco.in/item?id=503

I see.  Since the bet deadline is always at least one day prior to the event date, there was no reason to change it because the event date did not change -- the reference market was trading on December 31st.   So it doesn't seem justified for the deadline to have changed in this instance.

Hi looking all over the web and cannot find any recent info on ASIC status. anyone know if BFL or any of the others have started shipping ASICS? Or more delays?


This is an ASIC created for bitcoin mining.  One of these hashes at about half the level of what an AMD 7970 does:

2284  Other / Beginners & Help / Re: Bitinstant - only these countries?? on: January 01, 2013, 06:42:53 AM
I need to buy bitcoins using moneygram.
But if I go to bitinstant, when I have to select the country it only shows a few of them, what happened??
I live in Switzerland, and I remember that last month there were a lot more countries available...

They were beta-testing an on-line bank transfer method that was available in a number of countries but then they removed that option.   They didn't yet support MoneyGram from the EU as far as I know.

I see that UKash is available in Switzerland.  That can be used for purchasing bitcoins from VirWoX, BitcoinNordic, and Mercabit.eu.  The rate isn't that great but it is one method.

There are also many, many sellers who will sell bitcoins to you face-to-face:
 - http://localbitcoins.com/country/ch

If you must do MoneyGram, then WM-Center and ECurrencyZone are two of these exchanges that do this:
 - http://en.bitcoin.it/wiki/WM-Center
 - http://en.bitcoin.it/wiki/ECurrencyZone

There may be other methods that work for you as well:

2285  Bitcoin / Legal / Re: Bitcoin and DWOLLA and CampBX on: January 01, 2013, 01:40:08 AM
So what if I DON'T get money TRANSFERED TO ME, instead "deposited" aaaaaaand then sent to CAMPBX.  Would I still need a permission slip signed by mommie, i mean DWOLLA? 

I can't see how Dwolla would know nor care where the funds deposited to your bank account came from before they pull them to your Dwolla account.

or did I find a loop hole everyone else is already using,

There is only one exchange in the U.S. that still has an anonymous cash-deposit-at-a-bank method.  After depositing cash at a Chase bank into BitMe's account, those funds get credited to the person's BitMe exchange account.   But then those funds are used to satisfy ACH withdrawals so the exchange doesn't need to get those funds to an exchange to "restock".
 - http://www.BitMe.com

There is a bulk buyer who will accept cash deposits of large amounts ($1,000 or more) at B of A, Wells Fargo, or PNC Bank, though they currently are not accepting new clients:
 - http://bitcointalk.org/index.php?topic=87094.0

What they do (very well) is hold a large chunk of funds in reserve so that they can meet daily demand while funds from previous sales are flowing through the bank system.  For example, cash deposits at Wells Fargo might be sent as an ACH transaction to their B of A account which is then used for their payments.  So performing proper cash management is the approach they use to accommodate the delay between when a transaction is initiated and when those funds are available for use at the proper destination.

2288  Other / Beginners & Help / Re: Bitcoin sale gone bad on: December 31, 2012, 09:55:34 PM
My question is how that happened?

How what happened?

If you are not familiar with how PayPal operates, they will often place a payment received "on hold" and the reasons vary.  Sometimes they release the funds days later, and other times they don't.

But now you are on PayPal's radar.  If they haven't freezed your PayPal account (and any funds you had not yet withdrawn), it is just a matter of time before they do.

2289  Bitcoin / Legal / Re: Bitcoin and DWOLLA and CampBX on: December 31, 2012, 09:22:27 PM
And it's aggravating that a service offers something that when utilized gets a user suspended.

It is pretty clear:

User Conduct
You understand and agree that you will not engage in the following activities:
● Act as a marketplace and/or exchange for virtual currency products without prior written consent;

That was written SPECIFICALLY with bitcoin in mind.

They can't know that a transfer between two people was for the exchange of baseball cards or bitcoins, so it happens that people successfully trade bitcoins for Dwolla and vice-versa.    But when Dwolla figures it out (it aint that hard to do), they have the absolute right to no longer provide their service to you.

They didn't say "no exchanges ever allowed", they wrote: "without prior written consent".

Hope they dont run off with our money...

Looking dodgy atm no word from support and the guys no where to be seen... hmm

You know, ... slinging accusations like that are damaging.  

Do you really believe this service that has been operating for over a year now and provides so much for Bitcoin (nearly all of it free of charge to users, incidentally), is thinking that the best option from here is to throw it all away and run off with your £200 GBP?

Or, might it be that it was a holiday weekend, maybe short staff at Qkos, or at Barclays or a combination of the two?

This isn't the first time you've pulled out the "scam card" as leverage.   From another thread:

Yes like i said my first transaction went fine. this one just seems dodgy

Not saying they scam just wondering whats happening and i hope i get my money

Yes, it sucks when the banking system doesn't work fast and perfect each and every time.  Bitch at Blockchain.info about being slow here.  Bitch about there not being good communications (nothing is on their thread or anywhere else explaining the delays).

But please do not sling accusations that are not deserved.
2291  Economy / Service Announcements / Re: Bets of Bitcoin - Bitcoin betting on real world events on: December 31, 2012, 07:16:25 PM
Reference market was closed for a day and that's a reason to change the deadline?

It is not reasonable to expect that Bets of Bitcoin to be a domain expert regarding every detail of every bet statement submitted.

In this instance,the bet submitter didn't know to specify the proper bet deadline. [Edited] The deadline couldn't be December 31st, because that is the day the event occurs, and thus if it still were open the site would continue taking bets placed after the outcome was already known.   So the earliest deadline for this bet then became December 27th.  [Edit: Incorrect.  The reference market did trade on December 31st.]

This is no different from the message you'll see at a casino: "machine malfunction voids all payouts".

Your wager wasn't lost.  The bets made after the revised deadline were returned to bettors.

2293  Bitcoin / Technical Support / Re: Help - lost bitcoins!! on: December 31, 2012, 06:58:20 PM
So now I have a choice. Redownload the entire blockchain using this wallet, or use a slightly older backup that was like this one

If you know what the balance should be (i.e., to know if the backup was recent enough) simply rename the existing wallet.dat (to something like wallet.err) and restore from the other backup.   [Edit: Use -rescan if needed] If the balance is correct, use that one.

If that did not have all the keys, then you want to try to salvage the wallet (available since v0.7.1):

* -salvagewallet command-line option, which moves any existing wallet.dat
  to wallet.{timestamp}.dat and then attempts to salvage public/private
  keys and master encryption keys (if the wallet is encrypted) into
  a new wallet.dat. This should only be used if your wallet becomes
  corrupted, and is not intended to replace regular wallet backups.

With more here: Unauthorized Account Activity on my Mt.Gox Account - Account Compromised/Hacked?
 - http://bitcointalk.org/index.php?topic=94140.0

And on other services as well. Here same thing happened to some GLBSE users:

And elsewhere, BitMarket.eu in this instance:
 - http://bitcointalk.org/index.php?topic=5441.msg1259168#msg1259168

And now on bitcoin.de as well: Bitcoins stolen from bitcoin.de.
 - http://bitcointalk.org/index.php?topic=130264.0

In none of these was the person using multi-factor authentication. Mt. Gox has had Yubikey support for a while. Mt. Gox accounts now support Google Authenticator as well:
 - https://mtgox.com/press_release_20120605.html


This is advice you will see shared by many here:

If the exchange you are storing funds with doesn't provide OTP, consider using a different exchange:
 - http://bitcoin.stackexchange.com/questions/4113/which-two-factor-authentication-methods-are-available-at-which-exchanges

If you are storing funds in an EWallet, consider using a paper wallet.

Here is a fantastic guide: How to use 2-factor auth on mtgox, even without a smartphone (from a second device, of course, not from the same computer you log in on).
 - http://bitcointalk.org/index.php?topic=111943.0

it's currently more secure than an opt-in GAuth. (for the average user)

You could offer each user the choice -- Master Key or OTP.
2295  Bitcoin / Technical Support / Re: Help - lost bitcoins!! on: December 31, 2012, 01:19:41 PM
I feel a bit stupid for bothering everyone with this.....

Don't -- it is a good reminder to others who might just have made a recent backup after empathizing with you.

The wallet.dat contains, by default. a key pool of the next 100 addresses your client will use.  An address is consumed each time you click "New Address" and then each time a change transaction (back to yourself) is made it pulls one address from the key pool.   The keypool is topped up after each time an address is drawn from it.  (with a few exceptions).

So you as long as your backup is newer than the past 100 transactions it should have all the keys in it.

A small amount well under the verification limit.

That doesn't mean they won't ask for AML documentation for "suspicious activity"

Quote
Mt. Gox will request identification information (such as an identity card, invoices, Government issued photographic identification, utility bill, residential certificate, signed certification of cohabitation, or similar, banking information) depending on the amounts deposited on the Accounts or the presence of suspicious activity which may indicate money-laundering or other illegal activity.
- https://mtgox.com/terms_of_service

They said that the money has been caught up for AML review.

It is a manual process, and they are "limited" for the holidays:

Quote
From December 24th to January 7th, Mt.Gox will work in limited capacity

Mt Gox should have a better support over the holiday period.

Someone trying to influence the exchange rate knowing that big a rise in these types of metrics tend to pull the price up as well?

extract data points from the blockchain.info charts to import into an excell-like program

Normally you could just get the data in JSON:

e.g., for the chart:
 - http://blockchain.info/charts/market-cap?timespan=all

Just add &format=json
 - http://blockchain.info/charts/market-cap?timespan=all&format=json

Except at the moment that is displaying an error -- "Unknown Exception".

Sometimes there are multiple sources for the data.  E.g., BitcoinCharts has the ability to display a table of the data in the charts -- just click "Load raw data".
