Kötümser haberler tek bir ağızdan çıkmışçasına yayınlanıyor, ben bunun bilerek yapıldığını ve piyasanın manipule edildiğini düşünüyorum fakat yine de piyasa hakkındaki sakinliğimi koruyacağım.. Herhangi bir satış yapmayı düşünmüyorum, bitcoinleri saklamaya devam ediyorum.

Herkesin sermayesi büyük miktarda eridi fakat yatırdığınız para zararda değilse herhangi bir sorun yaşayacağınızı düşünmüyorum.. Bana göre elinizdeki coin miktarı azalmadığı sürece bu piyasada hiçbir zaman zararda değilsinizdir, önemli olan eldeki bitcoin ve ethereum sayısıdır.

Sene sonunda merkezsiz borsalar geldiğinde hiçbir devlet kriptoparaların ticaretini engelleyemeyecek konuma gelecek ve aynı zamanda Japonya'nın Mt. Gox'tan el koyduğu yüzbinlerce Bitcoin, Silk road zamanında Amerika'nın ceplediği Bitcoinler, BTC-e'de el konulanlar, Rusya'nın Ethereum'u, Çin'in Neo'su, Güney Kore'nin yüksek bitcoin hacmi.. Tüm bunlar birleştiğinde kimsenin amacının Bitcoin'i yasaklamak değil aslında eldeki bitcoin sayılarını arttırmak olduğunu görüyoruz.

How many central banks are actually considering their own version of cryptocurrency is unclear, Russia and Venezuela being the most infamous examples. To perhaps ward off serious consideration from more established economies, the Bank for International Settlements (BIS), the world’s central bank to central bankers, is suggesting state-backed crypto might destabilize commercial banks’ customer deposits, negatively impacting the “efficiency of financial intermediation.”

Central Banks Warned About State-Backed Crypto

Chairs of two BIS working groups, Klaus Löber (European Central Bank) and Aerdt Houben (Netherlands Bank), submitted Central Bank Digital Currencies, a 34-page document meant to be a “high-level overview of [central bank digital currency (CBDC)] implications for payments, monetary policy and financial stability. The analysis of the committees reflects initial thinking in this rapidly evolving area and is a starting point for further discussion and research. It also highlights that the issuance of a CBDC requires careful consideration,” it outlines in the Foreword.

The word, “careful,” in one form or another, is sprinkled half a dozen times throughout, as in “Any steps towards the possible launch of a CBDC should be subject to careful and thorough consideration. Further research on the possible effects on interest rates, the structure of intermediation, financial stability and financial supervision is warranted. The effects on movements in exchange rates and other asset prices remain largely unknown and also deserve further exploration.”


The BIS has been particularly vocal of late on the subject of crypto, as when last month its General Manager stressed “while perhaps intended as an alternative payment system with no government involvement, it has become a combination of a bubble, a Ponzi scheme and an environmental disaster.” The 87 year old, Basel, Switzerland-based central bank is the world’s lender of last resort to the lenders of last resort.

The report is revealing in the sense it appears cryptocurrency is an increasingly important topic of conversation, and that at least some central banks are considering competing alternatives as perhaps an answer. Where last month’s BIS comments dismissed crypto, the present report doesn’t outright condemn a state-backed coin. The paper “finds that wholesale CBDCs might be useful for payments but more work is needed to assess the full potential. Although a CBDC would not alter the basic mechanics of monetary policy implementation, its transmission could be affected.”

Wholesale Is Preferable for Central Banks

“Many forms of CBDC are possible,” the report emphasizes, “with different implications for payment systems, monetary policy transmission as well as the structure and stability of the financial system. Two main CBDC variants are analysed in this report: a wholesale and a general purpose one. The wholesale variant would limit access to a predefined group of users, while the general purpose one would be widely accessible.”

By contrast, “A general purpose CBDC could have wide-ranging implications for banks and the financial system. Commercial banks’ reliance on customer deposits may become less stable, as deposits could more easily take flight to the central bank in times of stress. Besides consequences for financial stability, effects on the efficiency of financial intermediation need to be carefully considered,” the authors detailed.

World’s Central Bank: Crypto Could Risk Commercial Bank Deposit Runs, Instability
Aerdt Houben
To buttress the wholesale point, the report continues to argue, “Wholesale CBDCs, combined with the use of distributed ledger technology, may enhance settlement efficiency for transactions involving securities and derivatives. Currently proposed implementations for wholesale payments – designed to comply with existing central bank system requirements relating to capacity, efficiency and robustness – look broadly similar to, and not clearly superior to, existing infrastructures. While future proofs of concept may rely on different system designs, more experimentation and experience would be required before central banks can usefully and safely implement new technologies supporting a wholesale CBDC variant.”

Again, this is all very revealing. Too much “general purpose” crypto, even state backed, would destabilize economies, but that doesn’t mean more obviously efficient aspects of the technology shouldn’t be employed as a settlement layer behind the scenes, central bank to central bank. Of course, the BIS loves blockchain technology, and so far the only developed economy seriously flirting with some kind of central bank cryptocurrency is Sweden’s Riksbank (its study for the “e-krona” won’t be ready until next year).

Because people know that Bitcoin will be much more valuable in the future, so people do not worry Bitcoin drops the price. This market needs more experienced traders.

Eos is getting ready to set up a decentralized cryptocurrency exchange for the future. Binance, Bitfinex and Eos will produce a decentralized exchange for cryptocurrencies. That's why I think Eos will be valued.

İngiltere merkezli danışmanlık firması Pricewaterhouse Coopers (PwC) blockchain analiz edebilen bir yazılım geliştirdiği duyurdu. Yazılım sayesinde ICO coin’leri takip edilebilecek. Böylece kullanıcı sahip olduğu kripto paranın herhangi bir yasa dışı işlemde kullanılmadığından emin olabilecek.

PwC ve Hong Kong’lu ortağı Eric Young Asya’da ICO’lara ve kripto paralara artan ilginin projeye ilham verdiğini ifade etti. Yatırımcılar Çin’in kripto paralara karşı yasaklayıcı kanunları dolayısıyla yeni pazar arayışına girmişlerdi. Bu yüzden yatırımcılar kripto paralara daha sıcak bakan ülkelere yöneldiler. PwC Asya’daki Hong Kong’a yönelen kripto para yatırımcıları için sermaye sağlamayı planlıyor. Geliştirilen yazılım hem şirketler için hem de yatırımcılar için daha güvenli bir ortam sağlayacak.

Young ICO sırasında satın alınan kripto paranın piyasaya sürülmeden önce yatırımcı tarafından takip edebileceğini öne sürdü. Bu sayede ICO’yu düzenleyen şirket yatırımcılardan habersiz olarak coin’leri kullanamayacak. Young şöyle konuştu:

PwC geçtiğimiz aylarda ICO düzenlemeyi planlayan birkaç şirketle beraber çalışmaya başladı ve şirketlere yasalarla ilgili danışmanlık yaptı. Diğer yandan şirketleri kara para aklamaya karşı alınacak önlemler hakkında bilgilendirdi. Geçtiğimiz yıl Kasım ayında PwC’nin Hong Kong danışmanlık ofisi ödemelerde bitcoin kabul edeceğini açıklamıştı.

Binance Chain diye bahsedilen coin kendi merkezsiz borsasını oluşturmayı amaçlıyor, Türk websitelerinde haberi olmasada www.ccn.com üzerinde detayları bulabilirsiniz bunun dışında şu an kendi merkezsiz borsasını oluşturmayı düşünen borsalar (Bitfinex, Binance), kendi merkezsiz borsasını oluşturmayı düşünen coinler (Eos)

Bu tür büyük firmalar varken Waves gibi hantal projeler yem olacaktır, bu saatten sonra yükselmesi anca balinaların zevkine bağlıdır ama Waves 1.5 yıldır ortaya düzgün bir borsa koyamadı.

Geçtiğimiz bir kaç yıl içerisinde en büyük ikinci kripto para birimi olmayı başaran Ethereum, Bitcoin ile kıyasladığımızda daha pozitif yorumlar alan bir kripto para oldu. Ethereum, hem geliştiricilerin çalışmaları hem de yatırımcıların güveni sayesinde dünya çapında popüler bir teknoloji olmayı başardı.

Tek bir makalede Ethereum ve onun teknolojisini anlatmak pek kolay olmayacaktır, ancak dilerseniz sitemizden Altcoin’ler başlığını takip ederek daha detaylı ve teknik bilgilere ulaşabilirsiniz. Haber ve makaleleri inceleyerek de hem konunun uzmanlık alanına girmiş olursunuz hem de Ethereum fork’ları ve bu teknolojinin nasıl atılım yaptığı ve dünya genelinde bu kadar popülerleşmesinin süreçlerine tanık olabilirsiniz.

Ethereum Nedir?

Ethereum’un diğer kripto paralardan ayıran başlıca özelliği, sıradan bir kripto para birimi olmamasıdır. Ethereum, Blockchain teknolojisi ile işleyen ve akıllı sözleşmeler ile Ethereum Sanal Makinesi’ne (EVM) dayanan çok amaçlı bir platformdur. Yani Ethereum, akıllı sözleşmeler yapmak için kullanılabilir.

Blockchain üzerinde saklanan Ethereum akıllı sözleşmeleri, anlaşmaları ve düzenlemeleri basitleştirmek için de kullanılabilir. Bu tür sözleşmelerin asıl avantajı, Blockchain’in merkezsiz olan kontrol ve yürütme sisteminin kullanılmasına izin vermesidir. Bu sistem ise sahtekarlıkları önler ve işlemin değiştirilmesini imkansız hale getirir. Ayrıca Ethereum akıllı sözleşmeleri, geleneksel yolla yapılan sözleşmeler ile karşılaştırıldığında, Ethereum’un, çok daha güvenli olduğu ve düşük işlem ücretleri sağlamak üzere tasarlandığı görülür.

Akıllı sözleşmelerin ekleri, Blockchain teknolojisini kullanarak Ethereum temelinde çalışır. Ayrıca Ethereum, diğer kripto paralar gibi kripto para cüzdanlarında saklanabilir ve bu cüzdanlar akıllı sözleşmeler yaratıp kullanmaya imkan tanır.

Kripto Paranızı Kullanarak Akıllı Sözleşmeler Yaratabilirsiniz

Ethereum kullanıcılarına; dijital hisse senetlerinde ve dijital varlıklarda kullanılabilecekleri token’ler üretme şansı tanır. Bu tip akıllı sözleşmeler; standart kripto API kullanıcısı veya herhangi bir borsa ve kripto para cüzdanı ile uyumludur. Bunun yanında hisse senedi sunma, oy kullanma ve bağış toplama gibi farklı amaçlarla kullanmak için Ethereum web sitesinden kodlar da kopyalanabilir. Bu platformda asıl mümkün olan şey ise, belli sayıda token’i belirli kurallar çerçevesinde serbest bırakmaktır.

Bitcoin ve Ethereum Arasındaki En Büyük İki Fark

man, only invest in bitcoin for long term. Ripple, Neo, Stratis etc is very risky but high volatility.. You can earn high profits from these coins.

Litecoin never die but i do not think Litecoin will be valued anymore. Since Bitcoin's transfer rate has increased, Litecoin has not had any prospects.

The top regulator at the US Securities and Exchange Commission (SEC) has fired yet another warning shot at initial coin offerings (ICOs) that are being used to mask unregistered securities offerings.

In an interview with Fox Business, SEC Chairman Jay Clayton reiterated that a significant portion of the ICOs that he has observed qualify as securities offerings, even though they are marketed as utility token sales and claim that they are exempt from securities regulations.

Clayton said:


These are among the SEC chairman’s first public statements on this nascent fundraising model since reports emerged that the agency had issued subpoenas to as many as 80 ICO operators, demanding that they turn over documents related to their token sales.

The SEC is also investigating other offerings — including that of tZero, a subsidiary of e-commerce company Overstock — although these companies have reportedly been asked to hand over documents voluntarily.

In a lengthy exchange, Clayton detailed one of the SEC’s chief problems with the state of the ICO markets, namely that issuers appear determined to “break down [the] traditional approach to public and private markets.” He explained that under SEC guidelines, securities issuers may choose to either conduct their offering as a private placement or as a public offering. Most ICOs, he said, have tried to do both.


Meanwhile, a newly-released letter drafted by an official with the Department of the Treasury suggests that ICOs may also have to register as money transfer businesses, which would subject them to the Bank Secrecy Act and other regulations that, if violated, incur criminal penalties.

Clayton advised investors to “think long and hard” before contributing to ICOs that do not explicitly demonstrate their compliance with SEC regulations, noting that there is little the agency can do to protect investors once the money moves offshore.

But for ICO operators, he had a more explicit admonition:

“Abide by the law,” he warned, “we are watching, others are watching.”

Bitcoin price hit a 10-day low of $9,400 (Bitfinex) as major cryptocurrency exchange Binance froze withdrawals due to “unauthorized market sells.”

Bitcoin shed some of its recent gains today, dropping over 10% on the back of rumors that Binance, one of the world’s largest crypto exchanges by trading volumes, has been hacked.

“WTF is happening! Binance just sold all my alts at market rate and I have got just the Bitcoin now,” a user wrote on Binance’s official Reddit page. “Is it because of account getting hacked or binance bot issue?” Other users expressed similar concerns with their crypto holdings.

Following up with a statement, a moderator for the exchange announced a temporary freeze on withdrawals insisting that the victims, recognized thus far, have registered API keys  – commonly used in trading bots and Binance’s mobile and desktop applications. Binance insists that its platform has not been hacked.

The Binance representative wrote:

At press time, bitcoin price is posting a recovery in trading near $9,700.

Several traders at popular cryptocurrency exchange Binance are reporting that the platform executed unauthorized orders through their accounts, triggering a 400 percent pump for lesser-known altcoin Viacoin.

On Wednesday, Binance users began flooding the exchange’s Reddit page with reports that their accounts had executed unauthorized buy and sell orders.


“Everything was cleaned out from my account. Now even Bitcoin is gone. It was used to buy some random Via coin. All value gone,” the user added soon after.

“Same Here! Buy Order executed VIAcoin at horrendous prices,” another user replied.

Indeed, Binance exchange data indicates that a ~325,000 VIA buy order placed shortly before 3 pm UTC increased the price of VIA/BTC by several hundred percent.



A Binance representative quickly responded that the exchange is aware of the issue and is currently investigating it.


Most of the affected users said that they had checked their login history for evidence of unauthorized access but said there was no suspicious activity, and several added that they have two-factor authentication (2FA) activated as an extra security measure.

Even so, the incident appeared to affect a limited number of users, and Binance later announced a temporary freeze on withdrawals, claiming that all of the victims it has identified had registered API keys — which are commonly used in trading bots.

The company said that there is “no evidence” that Binance itself had been compromised, and CEO Changpeng Zhoa stated on Twitter that “all funds are safe.”


If the traders’ accounts were compromised through their API keys — which could have been accomplished through a phishing scheme — the hacker would likely have been able to trade on the accounts but not make withdrawals. Consequently, as one trader explained, the hacker likely used Viacoin buy and sell orders to launder the funds to his or her personal account.

However, several affected users protest that they did not use trading bots, and rumors that Binance was hacked continue to circulate through social media channels. These rumors, as CCN reported, have correlated with a significant Bitcoin price downturn.

Wepower'i bu fiyattan satan enayilere bir anlam veremiyorum gerçekten -%18 zararda olan bir coini neden satarki insanlar? fiyat zaten çakılmışken daha da çakılmasını isteyen bir politika ile yönetiyorlar.. ben bu kadar düşeceğini ve bugün dağıtılacağını düşünmüyordum.

Eğer altcoinlerdeysem Bitcoin'e, Bitcoin'deysem yarısıyla altcoinlere geçiş yapardım çünkü zaten bitcoin yükselmezse hiçbir kriptopara yükselmiyor ama eğer bitcoin yükselirse altcoinler daha da bir güzel yükseliyor dolayısıyla edo, poa, zrx gibi garanti kazanç getirebilecek coinlere yatırım yapılabilir.

Eğer tüm ülkeler bitcoin'i bu şekilde vergilendirseydi emin olun bugün 100 bin dolardan değil, 1 bitcoin'in 1 milyon dolar olabileceğinden bahsediyor olurduk.. Ben bu verginin uzun süre bu seviyede kalacağını düşünmüyorum, bir para birimi gibi vergilendirilmiş, aslında olması gereken bu ama böyle olması çok zor.

Türkiye'den kimsenin hesabı çalınmadı mı? Yani bu haberler neden hep yurt dışından geliyor anlamak zor doğrusu.. neyseki bizden kimsenin canı yanmamış ben paramı ledger cüzdanda tuttuğum için herhangi bir sorun yaşamadım size de paranızı borsada tutmamanız için bir ders olsun.

Rabobank, a major Dutch bank with €681 bln under management, roughly equal to $838 bln, is looking into options for developing a cryptocurrency wallet within its online banking environment, according to a press release published Feb. 28.

The idea of a digital wallet for the bank’s own cryptocurrency project “Rabobit” was offered under the bank’s internal “Moonshot” program. The program encourages Rabobank’s employees to propose innovative ideas which can be further developed by the bank.

Although the bank’s official selection of “Moonshot” ideas for actual implementation will be announced in mid-June, Rabobank has already launched a one-page website to promote its potential Blockchain-based service and evaluate the public interest towards it.

According to the one-pager, if released, Rabobit will offer access to all of a customer’s funds “through one bank account”, and allow to “send and receive funds, including cryptocurrencies, in one environment.”

Rabobank, an international financial services provider that has approximately 8.7 million clients around the world, has not always maintained such an open-minded approach to the digital currencies. Last month, an unnamed representative of the bank stated that they considered Bitcoin to be a “risky” product, according to the NL Times news site.

“Ownership and value transfer are completely anonymous and evade supervision by third parties, such as a government. Which means that cryptocurrency does not meet the highest standards of compliance set by Rabobank," the bank’s representative said.

Back in November 2017, another major bank, South Korea’s Shinhan Bank, announced it was in the process of developing its own cryptocurrency wallet. However, disagreements among South Korean authorities about the correct approach to cryptocurrency regulation has put Shinhan’s plans on hold.

Much of the growing interest in Bitcoin and other digital currencies has focused on getting and not giving. But flying under the radar is an exciting new trend toward leveraging cryptocurrencies for philanthropy.

Fundraising with Crypto

Over the last few years, a number of charities and foundations have been trialing Bitcoin donations. These include such well-known organizations as the Red Cross, Save the Children, United Way and the Electronic Frontier Foundation. Cryptocurrency donations to charity are clearly on the rise. Fidelity Charitable, which houses the nation’s largest donor-advised fund, received $69 mln in cryptocurrency donations in 2017, up from $7 mln received in 2015 and 2016 combined.

Beyond charity donations are many innovative platforms and projects happening in the emerging “crypto-philanthropy” space. These include crowdfunding platforms such as BitHope, which allows donors to make Bitcoin donations to selected charities for their fundraising campaigns. Besides, some new tools like GiveTrack and Alice can track the flow of donations from donor to a done openly, and to verify what charities have received and achieved, all on a Blockchain.

Charity coins

Beyond cryptocurrency donations and tracking, a number of social purposes digital coins have been created to support specific nonprofit programs and endeavors. Clean Water Coin, for example, was designed to raise money for the nonprofit charity and bring clean water to the families around the world. Pinkcoin, a philanthropy coin which allows investors to both donate to charity and to earn a return on their investment, is listed on major cryptocurrency exchanges and has performed well in comparison to other commercially traded digital currencies.  

Crypto-foundations

Another new arrival in the cryptocurrency for charity space is the “crypto-foundation.” One anonymous investor established a foundation to give away 5,057 Bitcoins.  The motto of the donor’s charity, the Pineapple Fund, is: “Because once you have enough money, money doesn’t matter.” So far, through the anonymous outreach of an individual who goes by the moniker of “pine,” $56 mln has been donated to 56 hand-selected charities.

Further down the road, we may even see an autonomous and decentralized foundation or fund, under which grant and financial distributions are made purely through the votes of holders of foundation created tokens. Such a “Distributed Autonomous Foundation” would be governed by an external collective of shareholders with the right to direct donation flows and even produce and fund project ideas through majority token rule.

Blockchain-based systems could also help to improve the reputation of charities. According to recent studies, one in three Americans are said to lack faith in nonprofits, many believing that these institutions spend too much of their budgets on overhead and too little directly on programs. Reduced overhead spending due to improved operational efficiencies and disintermediation through Blockchain technologies (e.g., direct donor to beneficiary giving) could help restore faith in charitable giving among skeptical givers. This, in turn, could lead to increased philanthropic engagement and a rise in overall giving.

In the future more charities, and even foundations could produce their own cryptocurrencies, the sale of which may enable a new sustainability model. A charity token exchange developed exclusively for the buying and selling of them, may one day bolster a new market-based approach to philanthropy in which both philanthropists and charities make money from trading “digital currencies for good.” Nonprofits and foundations could also engage in fundraising through token mining.

Despite unlimited opportunities, there are many challenges ahead. Most prominent among them is the fact that digital currency donations and Blockchain anchored systems are still new and untested in the world of philanthropy, and there are limited awareness and interest among individual givers, charities, and foundations.

What the future holds

In the short term, it is unlikely that cryptocurrency and Blockchain platforms will significantly disrupt or displace traditional philanthropy, but they will drive further innovation and experimentation in the sector.

As donations through Bitcoin and other digital currencies become more commonplace and acceptable and assuming the crypto market continues to flourish, crypto-philanthropy will indeed grow. There will also be more testing of smart contracts and Blockchain managed to give and to track which, if successful, could establish a new norm for transparency in philanthropy. Ultimately, as givers and beneficiaries interact more directly, we may see diminished roles for charities, aid agencies, and foundations - in some cases even the removal of these entities from the philanthropic equation.

On the flip side, if greater transparency in giving and impact does lead to increased confidence in charities, millions (or even billions) of dollars more could be generated for the social sector.

Regardless of which way the wind blows, it’s a brave new world just waiting to be explored by those wanting to give a little back.
