The crypto and security on the i-products are top-notch, too bad wallets can't make use of that.

So who's on ParityWatch today?

And which exchange(s) are we going by here? Gox is getting close to $1200.

Also, Happy Thanksgiving (if you're American).

We're all on parity watch.

Ironic we might hit on Thanksgiving?

I am undecided if we should postpone it until Jan 3rd.

Santa Claus might be more appropriate.

Man, what a culmination to this thread.

Satoshi Nakamoto is my Santa Claus, he comes each year on Jan 3rd, only those kids hanging alpaca socks will receive his gifts. Wink

It's not so easy to get money out of China by buying BTC from the exchanges. First, you need a valid bank account before you can put money on the exchange. Second, you need more verification before you can increase the daily 10BTC withdraw limit. Moreover, all these transactions are recorded by the exchange. I don't think anyone who wants to bring a lot of money SECRETLY out of China will use exchanges. There are many other ways for them to do that with much less risks. Even if they choose BTC, they will buy them from others out of exchange.  

Yes, you are correct.

I was commenting on Bitcoin as a currency being special for them, not specifically about Bitcoin bought from BTCChina
They can transfer money on their own, at home, without middle man and black market exchange rates

No way.

Hardly anyone buys with bank accounts these days, every Chinese has an Alipay(or Tenpay) account, it's instant, friendly, versatile, and 24/7(just reminds you how much of a dinosaur the banking system really is)

It's actually part of the reason why China's volume was so crazy, we can move huge bunches of fiats into the exchanges nearly instantly, unchecked by banks.

it is just as easy to use as BTC if not more so cuz to download the wallet its like sooo much faster.
Bitcoin was a lot faster too, back before it was widely used.

If Litecoin was ever actually used in real life for all these fast transactions you keep talking about it wouldn't scale any better than Bitcoin.

im not so sure about that, the ltc dev team is aware of the mistakes that btc made and is trying to fix them before we run into that problem.

but anyway its what people use first they sort of stick with, and for millions of chinese it seems to be ltc Smiley


im not a btc hater at all but i saw the advantages and ltc very early and well this is no shock at all to me.



and for the people who are expecting a dump, well it might correct down some but its not like us long time ltc holders are going to do anything.

All I know is that 1BTC in my paper wallet will never be spent no matter what.
Then what good is it?  Wink
What good is the gold in Ft. Knox? I mean, if there is some there.

Deterrence, the difference is it can be firmly in people's hands this time.
367  Bitcoin / Armory / Re: Offline Laptops on: November 28, 2013, 03:04:26 AM
Extra credit:  have the offline computer encrypted using a USB key, instead of a password.   Your wallet on the computer is already protected with a password, and using the same password for the disk encryption is mostly redundant (though it's better than nothing).    I know it's possible to /dev/random data on a USB key, and have the bootloader use that as the FS encryption key.  But it's been a long time since I've done that, so I don't remember how.

It will improve the "hardness" of the system if it is stolen, as long as you don't keep the USB key with the laptop.  If they don't have the USB key, there's basically no way to even brute force the FS encryption.  If the thief gets both the key and the system, well there's still the wallet password that has to be found (unless you wrote the unencrypted key data to disk;  which should not happen with standard Armory operations, but it's nice to have the extra layer of protection).

If anyone has more details about doing this, I'd love to be reminded.  I've been meaning to upgrade one of my offline systems to that method, but been too busy to go figure it out again.

What would happen if the key suffers several bitflips? It will stop working and you can't even figure out where the errors are.

A possible improvement is to store hash checksums sector by sector elsewhere, so assuming there are no more than two or three errors per sector, it would be feasible to check each sector and locate the errors.

Why this discussion is relevant:

Next week I'm giving a presentation and answering questions on Bitcoin to a group of CEOs, several of them Fortune 500, including the CEOs of two of the top five PoS system providers. Please feel free to tell me anything that's on your mind... (self.Bitcoin)

The submitter stated in a comment:

Quote
Large retailers won't take the risk of 0-confirmation transactions, even small ones. It's just a non-starter. Part of the reason I'm there, however, is to fix that.

A 1 versus 10 minute wait for an internet purchase could be significant.
There is an alternative I think, you first check if the sender's address has unconfirmed transactions, then wait a few seconds for propagation time, then for small-time purchase you can just deliver the goods, as race attack would have been infeasible and only Finney attack would work.

Besides, for online purchase of physical goods, there is no need to worry about confirmation time, since you have evidence for double spending, you can always refuse to deliver.

I agree that with the proper precautions (waiting a few seconds to see if there are double spend attempts, ensuring the transaction has a sufficient tx fee) 0-confs is enough for a point of sale transaction.

For online services however, there are two reasons why a faster block time would be an advantage: first, if the service offers withdrawals of bitcoin deposited, then they need to wait for at least one confirmation to ensure you're not withdrawing bitcoins that you double spent. Second, some services want to ship immediately upon the order being placed. Having to wait for a 10 minute confirmation versus a 1 minute confirmation before shipping makes a difference here.

It's also not convenient for a service to have to keep track of which completed purchases are still at 0-confirmations and wait until they have at least 1 before shipping. The merchant could more practically wait for 1 confirmation before confirming the purchase is complete with a 1 minute rather than 10 minute block interval target and avoid the need to wait for a separate 'shipping confirmation' after they've already confirmed the purchase with the customer.

Quote from: DeathandTaxes
Will the fraud losses be zero?  Probably not but they don't have to.   Especially for online merchants where CC fraud (and mitigation costs) is 5% or more on digital goods.    Getting that to "only" 1% would be a windfall for merchants.

True, however we can look at the real Bitcoin economy to see that not every service will allow 0-conf transactions.


Actually, if we have a user-friendly multisignature implementation, a possible recourse for online retailers could be this:

(1). ask the buyer to deposit/charge a certain amount of Bitcoin balance to an 2-of-2 address, should be enough for a month or two's purchase, this transaction must have enough confirmations to be valid;

(2)  the buyer should also leave an "exit address" for refunding;

(3) whenever the buyer wants to make a purchase, he could only spend from this address, or he has to wait for confirmations, every transaction from this address thus has to be signed by both the buyer and the retailer, in a user-freindly way;

(4)when the user requires a complete/partial refunding , both parties would sign the transaction to the 'exit address" described above.

This should allow enough security while greatly reducing the inconvenience.

Better still, if the user frequently purchase online, but not just in one single shop, he could put his bitcoins into an address multi-signed with an online payment processor, which handles payment processing for lots of merchants, the advantage over old school payment processor is they can't move your bitcoins elsewhere without your approval.

both, lol, just looking at the silver chart here, if you had asked me a year ago if we would have ever seen 19 again I would have laughed in your face...now I'm holding out for 17

It's tempting to make a connection between bitcoin boom and metal bust, but the market sizes are too different. The $ flowing into XBT is negligible compared to the $ exiting the metals, right? I think it's plain old "manipulation" of gold & silver?


Hardly anymore, in 2008 the LBMA OTC daily volume for silver is only something like USD 2-3 billion, http://www.lbma.org.uk/pages/index.cfm?page_id=50 , but keep in mind this is because silver is in a bear market, when Bitcoin was in a bear market its volume also went much higher, judging by this we could estimate that XBT has a little more than half the size of global silver market, which could not be called 'negligible' anymore.

You may ask, how does the third party verify if the buyer is lying when he requests a refund? Dead and simple, all delivery companies have a auto-tracking system, which will update the escrower about the status of the package, once the buyer signs the package(which is required if he wants to accept it), the escrower will be immediately informed, there will be no way for you to lie.

This is already how the chargeback system works.  When the buyer initiates a chargeback, the credit card company asks the merchant to produce a "proof of delivery" signature.  If the buyer signed for the product then the merchant doesn't have to eat the loss.  If the buyer did not sign for it, then the merchant does.  That's the idea, anyway.

Of course most products purchased online are delivered without requiring a signature and I don't see this changing, bitcoin or not.  Smaller ticket items are generally considered not wiorth the hassle. 

Also, however, customers can seek a chargeback for other reasons, such as the product not being as described, or being damaged. 

Well, here you will have to sign every package, or you don't get it.

As for unsatisification with the product, it will be handled differently according to the returning policy, the refund will be processed independently, rather than just reversing the original transaction.
374  Economy / Speculation / Re: Gold collapsing. Bitcoin UP. on: November 27, 2013, 12:56:06 PM

i dont trust the govt.


Me neither. Before Bitcoin I had no way of acting on that however and I had no choice. Now I'm pretty well hedged with my Bitcoin holdings.

Then again, pretty soon I'm going to have to report my assets to the IRS. Paying tax isn't nice but okay. The worst part is that they know what I have. What if they pull on me what the US pulled on Gold owners in 1933?

Maybe just cash out a small portion and tell them it's all you have?

I'm not planning to cash out all (I have to report market value).

Reporting less than I have would be tax evasion. Don't you think that's something I'll come to regret?


I am not a tax lawyer, but if I were you, I would report everything I would ever consider to sell and thus move into the fiat money system, but claim to have lost the keys to the rest, assuming the taxmen are not silly enough to think that charging me something roughly equivalent to the market fiat value of those bitcoins would make sense.

im not a tax lawyer either. However (in the UK) if i haven't "cashed out" BTC then there is no capital gain to be taxed. Unless I am hugely mistaken!



Not all countries use the same wealth tax structure. The Dutch law requires you to report all your assets on January 1st of each year and pay 1.2% (30% tax on a 4% hypothetical yield) on it. If you own a house this is excluded (for fucked up unfair reasons). You are allowed to subtract foreign paid other forms of wealth tax (such as foreign dividend-tax).

So exchanging Bitcoins for fiat or not is a non-issue. If my wealth goes up sufficiently and the Dutch system becomes too much of a hassle, Germany is close by Wink (I dislike the language though)

Oops, so you live in Europe?  Apologize for assming you are an American, otherwise I see no reason why you brought up executive order 6102.

The Dutch system, if true, is completely nuts should I say. There is no guarantee on the outcome of an investment, all of your hypothetical values could possibly be wiped out overnight, even for no reason other than you selling your assets to pay the tax, you can't just tax people like that.

Most assets are liable to Capital Gains Tax when you sell or dispose of them.


He is not worried about taxation on his unsold coins, he is worried that IRS may either hold him liable for underreporting his bitcoin holding or acquire the knowledge of the size of his holding, should he chooses to be honest with them, in which case the danger of being forced to turn over his entire holding cannot be ruled out in a 1933-ish "executive order 6102" scenario.

Wasn't the same argument made when litecoin came out.  I don't think anyone is going to launch an exact copy.

You pretty much said it yourself(except that we have several exact clones already). each coin has its unique features, and is thus uniquely useful in someways, unlike fiats, the success of one doesn't exclude the success of another.

Quote
  All will or currently have variations on the bitcoin idea.  And we haven't even had a single major corp or government try to do a coin of their own.  What happens if Google or Facebook does a coin.  They've experimented with their own sort of money before but it didn't take off possibly because people inherently saw it as easily manipulated but under a guise of a crypto how fast do you think googlecoin would spread?

Governments will either do it half-heartedly to prop the fiat scam further(which will fool no one and unlikely to be taken seriously), or if they abandon fiats for cryptos, then it's already "mission accomplished" for us.

About corporations, it has to benefit them in some ways to do so, if they release an open source coin which is decentralized and they have no control, it's entirely possible Bitcoin will incorporate its best attributes and evolve, if they want to take the burden of running and supporting it....well, they are looking for troubles to be honest.

We reached LTC:Silver ozt parity before BTC:gold.

LTC trading for $21.38 on BTC-e and silver $19.97.

Embarrasing for BTC!


Are you bloody kidding me? Ugh. Be careful what you wish for, people.

More than one very successful (from a market-cap perspective) crypto will ultimately devalue them all, if there are no material technical distinctions.

I get in twitter fights with gold-bugs and their ilk all the time, and the best leg they have to stand on (and my only lingering long-term hesitation about bitcoin, for that matter) is the alt-coin argument. I have to lean on "network effects" and "first-mover advantage" arguments to defend bitcoin's market-cap and longevity in this light, and strong non-distinct alts will break that argument.

That said, bitcoin has risen almost 10x recently, and litecoin is catching up to keep its old multiple (~1/40), so that's fine, but much more, and we start to have empirical issues that invalidate important theory.
That's one of those issues bitcoin will have to deal with if it is to truly succeed.  It's a fact that it's easily duplicated and therefore isn't as scarce as some proponents like to prophesize.  How the market handles that will determine the future of cryptos in general.  Just like gold cryptos are an outlet for the current developed world government malaise called modern finance.  That may last a long while or it may come to a spectacular end much faster.  If governments are forced by circumstances and citizens to get their act together the need for bitcoin or other cryptos may not be as great as it is now.

Simple duplicates will not take off, without a powerful network behind it it makes as much sense to buy it as it is to buy Zimbabwean dollars.

People believe in the 'strongest' network, it's as simple as that, saw FTC? One 51% attack and it's pretty much finished.

About LTC, it's good to see it alive and kicking, as it gives people plausible excuse to send their BTCs into a mixing wallet and the legislators nightmare trying to regulate it.
