1  Bitcoin / Bitcoin Discussion / Bitcoin XT has backdoor that may reveal real IP address of its users? on: August 20, 2015, 02:42:37 PM
Bitcoin XT contains an unmentioned addition which periodically downloads
lists of Tor IP addresses for blacklisting, this has considerable privacy
implications for hapless users which are being prompted to use the
software. The feature is not clearly described, is enabled by default,
and has a switch name which intentionally downplays what it is doing
(disableipprio). Furthermore these claimed anti-DoS measures are
trivially bypassed and so offer absolutely no protection whatsoever.

Connections are made over clearnet even when using a proxy or
onlynet=tor, which leaks connections on the P2P network with the real
location of the node. Knowledge of this traffic along with uptime metrics
from can allow observers to easily correlate the location and
identity of persons running Bitcoin nodes. Denial of service can also be
used to crash and force a restart of an interesting node, which will
cause them to make a new request to the blacklist endpoint via the
clearnet on relaunch at the same time their P2P connections are made
through a proxy. Requests to the blacklisting URL also use a custom
Bitcoin XT user agent which makes users distinct from other internet
traffic if you have access to the endpoints logs.


To conclude. NSA/CIA can run simple ddos attack which activates "Anti-DDOS" backdoor in XT client which blocks Tor connections and de-anonimyzes users by revealing their real IP addresses.

By the way this shit is initiated and coordinated by The US with the help of FinCEN. They are able to arrest all assets on US intermediary accounts of "suspected" foreign banks and demand billions of fines. This is how US found a way to loot any foreign bank.

6  Economy / Speculation / Does "Wash Trading" in China cause artificial drop of BTC price ? on: September 28, 2014, 07:55:31 PM
Zero fees and wash trades

While macro factors may account for China’s lead in bitcoin trading, specific details like fee structures on Chinese exchanges give a further boost to the amount of trades on Chinese exchanges.

Danielli pointed to OKCoin’s margin-trading structure as one reason trading volumes have grown on that exchange. As users trade more, they accumulate ‘reward points’ that allow them to borrow more yuan for margin trading. CNY-BTC trading is free on OKCoin and Huobi.

People are ‘trading with themselves’ to increase volume and get to [the desired points level],” Danielli said.

The sort of trading described by Danielli is illegal in US equities and commodities markets, where it’s known as ‘wash trading’. In these transactions, a security doesn’t technically change hands, and is effectively being traded by one party who takes both sides of the deal.

7  Economy / Speculation / Volume on exchanges on: September 07, 2014, 03:48:44 PM
Those who worries about current volume on exchanges should read this article.

Trading over the counter offers several advantages over placing an order on an exchange. For one thing, traders get to protect their capital from the effects of price slippage.

Slippage is what can happen when an investor sells a large block of coins on an exchange all at once. If the sell order is large enough, it can cause the price on the exchange to fall as it is filled. As a result, the seller can lose a substantial chunk of the proceeds by the time the entire order is filled.

Just how much of a trade is lost to slippage is difficult to quantify, according to George Samman, a co-founder of BTC.SX and a former portfolio manager at a New York investment firm. In a hypothetical trade where an investor sold 100 BTC on BitStamp at today’s price of about $490, he or she would stand to lose up to 10% to slippage.

“When someone is trying to put a block trade through and there’s not enough takers at a certain price level, then the price keeps dropping as bids keep getting lower and lower,” he said.

Other factors can come into play. Traders could be laying in wait with ‘false’ orders on the exchange to feel for large blocks coming to market. When some of those orders are filled, savvy traders could cancel the rest of their original orders, sensing that a big block is being traded, and quickly place new orders at lower prices

"There are people who put a lot of value in executing a full block of 1,000 or 5,000 coins at once.”

“The problem with OTC trading is that they are private. People get upset about that and they think there is some kind of manipulation going on. But in the markets today, there is less and less volume. Even in the equity markets, institutions are trading with each other and taking trades offline.”
8  Economy / Economics / Australia Seizes 360M From Dormant Bank Account (inactive for 3 years) on: June 14, 2014, 07:58:01 AM
The federal government has bagged an unprecedented $360 million from household bank accounts since a controversial change to unclaimed money laws, figures from the Australian Securities and Investments Commission show.

Pensioners and others saving for a rainy day have reported trying to access their savings only to discover their money had been seized by the government because it had been dormant for three years or more.

The government has collected more money from inactive bank accounts under the three-year rule than the total amount captured in the past five decades combined.

Do you have a bank account that you don't actively use or a safe deposit box that you have not checked on for a while?  If so, you might want to see if the government has grabbed your money.  This sounds absolutely crazy, but it is true.  All over the world, governments are shortening the time periods required before they can seize "dormant bank accounts" and "unclaimed property".

BTW, the same started to happen in the US and other countries.

Georgia’s Disposition of Unclaimed Properties Act sets the threshold as low as one year.

P.S. Still happy with your savings account ?
9  Bitcoin / Press / 2013-03-26 Why Bitcoin Can No Longer Work as a Virtual Currency, in 1 Paragraph on: March 27, 2014, 07:28:10 AM

The price at which a particular Bitcoin was acquired (and this is traceable) determines the capital gains on that particular Bitcoin when spent.  If I spend Bitcoin A, which I bought at $10, but is now worth $400, I’ve got a very different tax treatment than if I spend Bitcoin B, which I bought at $390. […] This means Bitcoins are not fungible, and that makes it unworkable as a currency.

LOL. How stupid is the author if he doesn't see the benefit of having PROFIT from bitcoin bought at $390 no matter of taxes Smiley
Isn't it obvious that using bitcoins that doubled in price and pay capital gain taxes is anyway better than holding wealth in static dollar bills.
10  Bitcoin / Press / [2014-03-27] CCN: Evidence That Transaction Malleability Did Not Bankrupt MtGox on: March 27, 2014, 06:45:48 AM

However, while MtGox claimed to have lost 850,000 bitcoins due to malleability attacks, we merely observed a total of 302,000 bitcoins ever being involved in malleability attacks. Of these, only 1,811 bitcoins were in attacks before MtGox stopped users from withdrawing bitcoins. Even more, 78.64% of these attacks were ineffective. As such, barely 386 bitcoins could have been stolen using malleability attacks from MtGox or from other businesses. Even if all of these attacks were targeted against MtGox, MtGox needs to explain the whereabouts of 849,600 bitcoins.

No surprise for me Smiley
11  Other / Politics & Society / VISA & MASTERCARD blocked Russians from accessing their money on: March 21, 2014, 05:05:07 PM
More details is here

I think it's good time to educate russians about the benefits of bitcoin.

I'm calling all russian speaking to start massive campaing promoting bitcoin in comments and discussions of relevant articles in russian press. May be their dumb authorities will finally realize that bitcoin is their friend.
12  Economy / Economics / VISA & MASTERCARD has cut Russian banks. Cardholders cannot access money. on: March 21, 2014, 04:37:16 PM

Many russian customers of "sanctioned" banks are trapped abroad and cannot  access their money.

This is really the precedent. Now we see the power of totalitarian financial authority of the world.

Hey Russia,  it's really time to start using bitcoin, don't you think so?

13  Economy / Speculation / Now we have 750,000 less bitcoins in circulation ? on: March 01, 2014, 02:26:22 AM
If Gox tells us truth, it means that there were up to 1.75M of phantom non existing bitcoins circulating in active trade during recent years.
Now they are vanished and we only have real existing bitcoins on exchanges (I hope).

Guess what would happen to the price soon?
14  Economy / Speculation / bitcoin is NOT BANNED in CHINA. The Chinese can still legally use bitcoin. on: December 05, 2013, 05:19:06 PM
At first, I'm thanking all the panicked chickens for cheap bitcoins. More newcomers have got their BTC at amazing price today.

Now, calm down and relax. Bitcoin is not banned in China.
Chinese central bank has only clarified that financial institutions (banks) cannot use bitcoins as mean of payment and It's pretty normal as they have CNY currency as legal tender.

People are free to trade Bitcoin even as China refrains from recognizing it as a currency in the short term, PBOC’s Deputy Governor Yi Gang was cited by the 21st Century Business Herald as saying last month.

15  Bitcoin / Press / 2013-12-02 Bitcoin's $13.50 To $1,200 Eleven Month Climb---Now Taxes on: December 02, 2013, 03:15:22 PM

One key question these days is whether you are taxable on the appreciation in Bitcoin you bought at $13.50 that is now worth $1,000. Currency wouldn’t be, but it isn’t clear that’s what Bitcoin is in the eyes of the IRS. Transactions in Bitcoin could be property, barter, foreign currency, or a financial instrument. Barter seems most logical, but not everyone agrees.

Some suggest marking Bitcoin to market each year, which would be a good deal for the IRS. Essentially, that would valuing and reporting gain or loss at the end of each year even if you continue to hold it. Surely no one will do that this year unless it is mandated, which it is not.

Indeed, until the IRS rules differently,  if you are holding highly appreciated Bitcoin you probably won’t be taxed until you dispose of it. That should be easy to track if you buy Bitcoin for cash and then sell it for cash. The difference is income, either capital or ordinary.

Yes, it's that guy who previously declared that bitcoin is a joke.

First of all, it's wrong to say that Bitcoin has no value. There's prima facie evidence that this is untrue.
17  Bitcoin / Press / 2013-11-25 theguardian: Majority of Silk Road's Bitcoins may remain unseized on: November 27, 2013, 06:13:53 PM

Almost 80% of the Bitcoins received by Dread Pirate Roberts (DPR), the pseudonymous head of the Silk Road digital black market, may not have been seized by the FBI, according to new research by two Israeli computer scientists.
18  Bitcoin / Press / 2013-11-27 NYTIMES: A Prediction: Bitcoin Is Doomed to Fail on: November 27, 2013, 06:03:05 PM

The developers of bitcoin are trying to show that money can be successfully privatized. They will fail, because money that is not issued by governments is always doomed to failure. Money is inevitably a tool of the state.

He's just forgot to add "Trust Me" in conclusion Smiley
19  Economy / Speculation / GREED KILLS, or simple rules for your Success on: November 27, 2013, 02:57:19 PM
To all the newcomers.

You will be successful bitcoin investor if you stick with these simple rules

- Never spend more than you afford to lose. It may kill you. This is the main rule.

- Never treat bitcoin as get rich quick scheme. Get ready to wait at least a year before you see gains.

- Never wait for price drops, buy at ATH and be happy when it doubles/triples in a year.

- Don't speculate during "All time highs", it will bite you.

- Don't panic. Never sell with losses, even when you see it's dropping 50% of its value in a minute. As history teaches, it's just another bear trap.

Abiding these rules will help you being happy and benefit bitcoin economy.
