Newscastix denen şahsiyet bana negatif trust göndermiş. https://bitcointalk.org/index.php?action=trust;u=22383

Bu hesap ile Kubra Dam isimli hesabı aynı kişi yönetiyormuş. Böyle bir şey yok. Şerefsizliğin de lüzumu yok.

Kubra Dam' ı bu konuya davet ediyorum. Kendisini tanımam. Bu yapılan şerefsizlik, haysiyetsizliktir. Ekmeğimle haksız yere oynayan bu şahsiyeti kınıyorum.

İmza kampanyalarından 3-5 kuruş kazanıyoruz. Bu kazanç üzerinde gözü olan veya benimle alakalı karın ağrısı olan asıl isim kim onu da biliyorum.

Kendisi de kendini biliyor. Yüzyüze görüşme talep ediyorum kendisiyle. Forumda yaptığı şerefsizliğin hesabını bire bir görüşerek çözmeyi teklif ediyorum kendisine.

Ufacık bir delikanlılık kırıntısı varsa içinde PM atsın...
5  Economy / Service Discussion / Petition Exchanges to take measures against volatility: Asymmetric fees on: April 03, 2014, 07:14:52 AM
A large spread and volatility are among the biggest impediments for wider adoption of Bitcoin payments. Too many people take liquidity and too few add it, making the book shallow, particularly around the current price. There were even times in the last few days on Stamp when the spread was more than $10 and trades happened all the time: As a result, people sold $10 cheaper than others bought, nearly simultaneously. That's 2.5% loss, sometimes more.

Under such conditions, Bitcoin payments are not cheaper than commercial payments, certainly more expensive than Paypal. Measures are needed to reduce the spread and volatility. A very powerful measure is to create incentives to add liquidity.

To increase the competitiveness of Bitcoin payments I propose to petition the exchanges to introduce asymmetric fees: If you add liquidity, you pay less. Maybe it should be even free. If you take liquidity, you pay more, or even all of the fees.

6  Economy / Speculation / Bitstamp news go unnoticed?! What influences prices these days? Gold? on: March 20, 2014, 07:15:10 AM
Bitstamp apparently received significant investment from Pantera:
http://www.reuters.com/article/2014/03/17/bitcoin-bitstamp-pantera-idUSL3N0ME26A20140317
Quote
Bitstamp just did a very extensive audit proving all of their balances, I know they're just starting a routine quarterly audit," Larsen added.
Yet apparently the market does not consider that noteworthy news which is astonishing, after the Gox debacle.

OTOH gold was going down the last few days. Is Bitcoin finally syncing with gold?
7  Economy / Speculation / Speculation Forum, Troll Box, Garbage can? on: February 24, 2014, 08:10:13 AM
This forum used to be about Speculation when I joined in 2011. While there are still posts of what I consider high quality, my impression is the the amount of junk / troll posts and even threads has considerably increased. Sure, posts like https://bitcointalk.org/index.php?topic=483658.msg5323143#msg5323143 always happened, but not in the density we see today.

I am wondering if most users of this forum see it as a garbage can where frustrated people can dump their intellectual excrement or if that is a minority polluting this forum for the rest of us.
8  Economy / Service Discussion / MtGox should be safe now OR both fiat and BTC deposits are gone on: February 20, 2014, 08:25:55 AM
Even if they used to be insolvent, they should be safe now since they had such a great opportunity to buy up coins for almost nothing. If they are smart they hold the announcement that Bitcoin withdrawal resumes just a little longer to buy at a ridiculous price and ARB as much as they can. By now they should easily have made good on the 5 Million they lost last year.

No idea why anyone thinks it makes a difference if they have fiat or BTC in case MtGox goes bust. We can assume that both is lost because very likely, they have other liabilities that are senior to deposits. Should BTC withdrawal resume, you are far better off with Bitcoin OTOH.

9  Economy / Service Discussion / Maker-Taker fee structure at BTC China on: January 08, 2014, 10:25:39 AM
A section from the "Happy new year mail" I just got from BTCChina:

Quote
Maker-Taker fee structure. This new innovative fee structure will maintain a small 0.3% commission for traders, while rewarding market makers with a rebate. (The reward is effectively a “negative” commission, for market makers.) In summary, our company will still not be making money in commission revenue, giving all the benefits to our customers. By having a trading commission, this will reduce market volatility and reduce wild price fluctuations, which we believe is good for the entire Bitcoin market and ecosystem.

Not sure about the details yet, but that should help inceasing market depth, reduce the spread and thus make Bitcoin more attractive for actual payment. Hey, we may even be able to shift the focus away from day-gambling on this board and do what the board name implies: Speculation
10  Bitcoin / Legal / Bafin (German equivalent to SEC) Regulation on Bitcoin on: January 07, 2014, 07:45:51 PM
http://www.bafin.de/SharedDocs/Veroeffentlichungen/DE/Fachartikel/2014/fa_bj_1401_bitcoins.html

This is probably the most Bitcoin friendly regulation I've seen so far. Also covers some Alt-Coin explicitly. I suggest everyone operating a Bitcoin business to read this carefully and decide if that justifies a relocation of the business, at least registration-wise.
11  Local / Presse / Substantiell negative Zinsen und der Überwachungsstaat on: November 21, 2013, 07:55:10 AM
Wenn irgendwer Zweifel hat, dass wir dringend Alternativen zum völlig aus den Fugen geratenen Geldsystem brauchen:
http://www.spiegel.de/wirtschaft/unternehmen/nullwachstum-debatte-wolfgang-muenchau-ueber-die-ewige-stagnation-a-934637.html

Also darum gehts: Bargeld abschaffen, damit die Leute ihr Geld nicht mehr abheben können und damit negativen Zinsen entkommen können. Typisch Keynesianer: Jede noch so dämliche Investition in weisse Elefanten muss besser sein, als Geld zu parken. Das führt zu gigantischen Fehlallokationen und der Kater nach so einer Party wird dann um so schlimmer. Aber das ist nicht das Schlimmste:

Als Nebeneffekt haben wir dann ein Geld, in dem der Staat beliebig Steuern erhöhen kann, weil er bei jedem Kauf in Echtzeit die Steuern erheben kann. Und nicht nur der Staat in dem wir uns befinden, sondern auch der des Käufers und des Verkäufers. Anonym Zug fahren ist dann nicht mehr drin. Und wenn der Staat nicht will, dass wir irgendwas tun, cancelt er einfach die Transaktion.

Um mal einen juristischen Unterschied aufzuzeigen: Um ein Konto zu sperren, braucht der Staat heute einen richterlichen Beschluss. Um aber ein Privileg zu entziehen, wie die Kooperation bei der Ausführung von E-Cash Transaktionen, braucht es gar nichts. Wenn der Staat nicht kooperiert, dann kannst Du nicht mal mehr eine Semmel kaufen. Dann gilt die Devise: Nichts tun, was den Staat auf den Plan rufen kann, wie etwa Demos gegen den Überwachungsstaat organisieren, Ayn Rand oder Nietzsche lesen.



Leute, das hier ist wichtig. Von allen Freiheiten ist ökonomische Freiheit die wichtigste, denn ohne ökonomische Freiheit sind alle anderen Freiheiten bedeutungslos. Durch das Giralgeldsystem ist unsere Freiheit ohnehin schon extrem eingeschränkt. Aber das hier beendet sie.

Bitte helft, diesen Wahnsinn zu stoppen. Bezahlt mit Bitcoin, wenn es geht, oder mit Bargeld, wenn es nicht geht. Verweigert Zahlungen mit EC-Karte, Kreditkarte, Chipkarte, Handy (ausser Bitcoin), RFID Implataten und Fingerabdrücken. Agitiert und verbreitet diese Message auf Foren, die ihr nutzt.
12  Local / Projektentwicklung / [ANN] Zero Reserve, eine verteilte Bitcoin Exchange on: September 17, 2013, 12:34:25 PM
X-post von https://bitcointalk.org/index.php?topic=295930.0


Zero Reserve ist eine verteilte Bitcoin Exchange. Sie kommt ohne Verbindung zum Bankensystem aus. ZR ist als Plugin für Zero Reserve implementiert und übernimmt dessen Friend-to-Friend Ansatz um die Ripple Idee umzusetzen. ZR hat aber mit Ripple.com nichts zu tun. Die Projektseite ist hier:

https://github.com/zeroreserve/ZeroReserve

Das Wiki:
https://github.com/zeroreserve/ZeroReserve/wiki

und ein Paper:
https://mega.co.nz/#!vZ80yQJS!ccrCBREYZrOPr8oK7C9StVGuDmYENNYwrFiPXZVQldM

Bitte beachtet, dass kürzlich eine neue Version von Retroshare erschienen ist und das Zero Reserve diese Version benötigt.
13  Bitcoin / Project Development / [ANNOUNCE] Zero Reserve - A distributed Bitcoin Exchange on: September 17, 2013, 12:13:01 PM
tl;dr: Proposal and prototype for a distributed exchange not requiring a banking gateway. Implemented as a plugin for Retroshare. Licensed under the LGPL.

The Achilles heel of Bitcoin is the exchanges. Centralized as they are, they can be stifled or even shut down by a number of means, by a number of players. Should that happen, price discovery of Bitcoin will not work any more. To address that, we offer a distributed exchange without the need of the banking system. Some intro is here:
https://github.com/zeroreserve/ZeroReserve/wiki

A tech paper is here:
https://github.com/zeroreserve/ZeroReserve/wiki/zeroreserve.pdf

In short, ZR uses the Ripple idea of Ryan Fugger to get money in and out of the exchange, although I prefer to give credit to Hawala. ZR has nothing to do whatsoever with ripple.com. There is no pre-mining, no company, just code, no strings attached.

This is still prototype software. Anything may or may not work. Security is only what the underlying Retroshare provides. Currencies are therefore only defunct or fantasy currencies such as German Papermark(1923) or micrograms of Fools Gold. Nothing you do has any effect on the real blockchain - its all TestNet.

Once the issue list has all serious issue resolved, we'll announce a final test run and then start the life network.

Zero Reserve has been developed on Linux. It builds and runs on Windows, too. OSX has never been tried, but there is no particular reason it should not work on this platform.

RetroShare (retroshare.sourceforge.net) is a prerequisite.. If you are not a user of RetroShare yet, recent NSA revelations suggest that you start now. Once you are on Retroshare and have some friends, you should be able to install and play with ZeroReserve. You should also be able  to use this link to get and subscribe to the Zero Reserve Forum:
retroshare://forum?name=ZeroReserve&id=b87d0a5577ced312d88a0ee8176e24a1

The code and an installation guide is here:
https://github.com/zeroreserve/ZeroReserve

Some setup is needed to get ZeroReserve ready to trade:
https://github.com/zeroreserve/ZeroReserve/wiki/Getting-started-with-Zero-Reserve

Please get involved to help make this happen. Everything, not only coding is of help: Media work - spreading the word, Graphics / web site design, Testing and anything that helps to get critical mass.
14  Other / Beginners & Help / How not to lose money when buying and selling on: April 30, 2013, 04:31:40 PM
Bitcoin price is volatile. Everyone knows that. Not only the big swings like from 13 to 266, back to 50, up to 100, back to 50, and up to where we are now, to recap just this year. This post is about not losing money in the smaller fluctuations that occur all the time.

I am usually setting both a sell and a buy order, about 15% away from the current price. And inevitably, sooner or later, it will be filled. When I receive my email that my order has been filled and log on to the exchange, the price usually already bounce back, so I can just place the opposite order. Rinse and repeat. It is a stupid way to make money, but it is very effective. But if I gain, someone has to lose. That loser is you, but this is not the reason I write this. But there is another loser of volatility, and that is the Bitcoin community as a whole. To avoid losing money and help Bitcoin strive, please read on.

There are 2 ways to place an order. You can either take liquidity or you can add liquidity. Doing the former increases volatility, doing the latter decreases volatility. Doing the former will lose you money, doing the latter will save you money. The following image is the market depth from MtGox today - a lot of liquidity has just been taken as you can see from the flat red line at the price of ~ $140:



Now what if you want to sell Bitcoins? Place a market order to sell before the price drops even lower? That's indeed what some do, they panic. And lose. The way not to lose money is to place the order within the range of low liquidity - maybe $141. This way it is very likely that your order gets filled quite quickly. And indeed, as I just added the last 2 lines, the liquidity takers took revenge and the price bounced to $141. You would have saved $3 per Bitcoin, just by being patient for 5 minutes.



The same is true if you buy Bitcoin, just vice versa. Just place your order so that it will not be filled immeditely.

What we all want is a market with a lot of depth. If only a few of the shaky hands would learn more patience, they would save their money, but more importantly, they would make Bitcoin much better suited for business.

15  Economy / Speculation / 260 is cheap, 60 is expensive, 130 is cheap on: April 19, 2013, 08:09:39 AM
I don't get it. Some buy at 260, apparently they think it is a good price. Later, they won't support when the price goes to 60, apparently because they think it is too expensive. Now, 130 seems a really good bargain to many again. All within a few days and without the tiniest change in what Bitcoin is.

Someone please explain the "buy high - sell low" strategy to me.

16  Bitcoin / Bitcoin Discussion / Proving you own a bitcoin address on: August 20, 2012, 09:30:17 AM
From my understanding, if you have some coins on a virgin Bitcoin address, the public key is a secret. Until you transfer money from that address, at which point the public key is known to the network.

So owning the public key of a virgin address should constitute proof that you also own the private key?

17  Bitcoin / Bitcoin Discussion / Flame Malware and trust authorities on: June 05, 2012, 06:57:21 AM
Slashdot has a story about how flame was signed with a MS certificate
http://news.slashdot.org/story/12/06/04/1211206/microsoft-certificate-was-used-to-sign-flame-malware

I am wondering if we could use that incident to show that *anything* that relies on central trust authorities must be avoided like the plague. Or, to be quite blunt, whether we could use this incident to spread massive FUD against all centralized payment infrastructures. Is it time to strike back?
18  Other / Politics & Society / Banning cash transaction - where is it going? on: April 20, 2012, 10:49:32 AM
A number of countries have banned cash transaction exceeding a certain limit, with more to follow. For now the average citizen won't usually reach this limit, maybe with the exception of trading a car from private to private. But the limits have been tightened in some countries already and it looks like the limits might be approaching zero at some point - doing away with cash entirely.

An incomplete list:
India: IRS 20,000 (~EUR 300)
Greece: EUR 1,500
Italy: EUR 1,000 - previously 2,500
Belgium: EUR 5,000 - 3,000 from 2014 on
Spain: EUR 2,500 (if one party is self employed)
Mexico: MXN 100,000 (~EUR 5,000)

Obviously, all the EMU countries in the list are those with budget problems, high tax fraud and high crime rates. Moving to a cashless society will "prove" to the world how detrimental anonymous payment is to society. Most will agree that we should trade some freedom for the security of drying up most sources of crime: cash. We have nothing to hide after all, do we?

The IMF tells us that 2-5% of the world wide economy involves money laundering. As most money laundering involves cash, a large part of cash transactions (up to half of them) would be illegitimate. What are we to make out of that?


IMO, a lot of well intentioned people are bent to driving us down the way to totalitarianism by making us totally dependent on the cooperation of the government for doing even such trivial things as buying a bagel and putting us under constant surveillance. If you ever loose this goodwill in a proprietary cashless society, you are done for. Bitcoin is one of the very few roadblocks on this way. If the governments around the world are serious with the "cashless society", they must dispose of Bitcoin at all cost, because Bitcoin shares too many properties with cash.

19  Economy / Economics / Greece bankruptcy imminent. Why don't we feel anyting? on: February 07, 2012, 11:39:38 AM
The exit of Greece from the EMU is only a matter of time now. Pretty short time at that - most EU politicians looking at March. One might think that the Greece try to get their (remaining) money out of their government's grasp ASAP. One way would be to open accounts on payment services like Paypal. But that seems quite risky. So some at least should get the idea to use Bitcoin as a value store for the next couple of months at least. We should feel some buying pressure. Why don't we?
