“Crypto מטבע אינדקס -מטבע דיגיטלי קודאק”

בעולם שבו הכסף הוא קריפטוגרפי, הרווחים האלו נמצאים בסכנה. פתאום, מי שמרוויחים מהדפסת כסף הם לא המדינה, אלא “הכורים”. מי שמייצרים את המטבעות הקריפטוגרפיים ומרוויחים מהם, הן החברות שמשקיעות את האנרגיה וכוח החישוב הנדרש כדי לקיים את המטבעות. בשפה פשוטה, כל העברה של ביטקוין (או מטבע קריפטוגרפי אחר) מחשבון לחשבון דורשת השקעה של כוח מחשוב אדיר בכדי לוודא שאכן בוצעה עסקה חוקית. בתמורה להשקעה של האנרגיה הזאת, מי שהשקיע אותה (“הכורים”) מתוגמלים במטבעות חדשים.

As of September 2017, over a thousand cryptocurrency specifications exist; most are similar to and derive from the first fully implemented decentralized cryptocurrency, bitcoin. Within cryptocurrency systems the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: members of the general public using their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[15] Miners have a financial incentive to maintain the security of a cryptocurrency ledger.[14]

A global ‘Airdrop’ of POW ‘lite’ with enough to be claimed by every person on the planet, can be easily claimed by logging in with your Facebook or Twitter account (if you have both you can make two claims!). POW has the potential to be the most widely held currency on the planet.

All banks and other financial institutions like payment processors are prohibited from transacting or dealing in bitcoin. Individuals, however, are free to deal in bitcoin between themselves. Bitcoin culture is thriving in China. It continues to be one of the worlds larges bitcoin markets.

What Civil wants to build is a combination of a publishing tool or platform like Medium—where anyone can post content and reach a broader audience—and a crowdfunding system like Patreon or Kickstarter. But all in a place that has been designed specifically to support independent journalism.

Cryptocurrencies have been compared to ponzi schemes, pyramid schemes[72] and economic bubbles,[73] such as housing market bubbles.[74] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were “nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it”, and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).[75] In October 2017, BlackRock CEO Larry Fink called bitcoin an ‘index of money laundering’.[76] “Bitcoin just shows you how much demand for money laundering there is in the world,” he said.

Now, some believe that application has appeared with the rise of the “token” economy, in which companies or startup ventures fund their operations by handing out units of cryptocurrencies. Some companies have even done what are known as “initial coin offerings” or ICOs, in which they distribute tokens instead of shares to investors.

Not yet. But our plan is to build a ‘bridge’ between POW ‘lite’ and POW ERC20 by Feb 2018. This bridge will allow you to transfer your POW ‘lite’ onto the Ethereum Blockchain where it will becom POW ERC20. You will then be free to sell your POW ERC20 for cash. So, in the long term, the answer to your question is yes.

But as cryptocurrency becomes more mainstream, ICOs will present greater risks to larger numbers of people. There are few barriers to participation aside from knowing how to conduct a Bitcoin transaction, and the space mostly lacks the robust independent analysis performed by underwriters in the IPO market, which can help tamp down overoptimism. The risk isn’t just to individual investors; many argue that the mania of the late-1990s internet bubble ultimately slowed the entire sector down by making investors skittish for years afterwards. Imagine how much worse things might have been if the whole thing had been entirely unregulated.

היתרון המרכזי של מטבע דיגיטלי הוא העובדה שקל להעביר אותו מאיש לאיש באמצעות מחשבים או סמארטפונים, מבלי לשלם עמלה כלשהי לגוף מתווך (בנק). יתרון נוסף הוא שהמטבע אינו מפוקח, ולכן אי אפשר לגבות דרכו מס על עסקות שונות.

Darknet markets present growing challenges in regard to legality. Bitcoins and other forms of cryptocurrency used in dark markets are not clearly or legally classified in almost all parts of the world. In the U.S., bitcoins are labelled as “virtual assets”. This type of ambiguous classification puts mounting pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[62]

A number of concerns have been raised regarding the cryptocurrency and ICO markets, including that, as they are currently operating, there is substantially less investor protection than in our traditional securities markets, with correspondingly greater opportunities for fraud and manipulation.  

יותר ויותר חברות פונות אל מסלול ה ICO כאלטרנטיבת מימון מהירה ונוחה יחסית ■ אין כל פסול בדרך המימון הזו, לפחות ככל שהיא קשורה ביזמים ישרים בעלי מיזם לגיטימי ■ הרבה מאוד משקיעים לא מקצועיים גם הפסידו הרבה כסף בהנפקות מטבעות קריפטוגרפיים ■ על היתרונות והחסרונות – בווידאו

Although we’re giving it away free, it’s worth something, and is even rising in value. That’s all down to the fact that ‘you’ are valuable, and when there are 100 million of ‘us’ connected in a network that is incredibly valuable. Just look at Bitcoin as a rule of thumb – Bitcoin has approximately 10 million holders and has a market capitalisation of $100 billion (as of Oct 2017) – that suggests a per user value of $10,000. If we are correct, that means the price of POW could rise dramatically as more and more people make claims.

It has been asserted that cryptocurrencies are not securities and that the offer and sale of cryptocurrencies are beyond the SEC’s jurisdiction.  Whether that assertion proves correct with respect to any digital asset that is labeled as a cryptocurrency will depend on the characteristics and use of that particular asset.  In any event, it is clear that, just as the SEC has a sharp focus on how U.S. dollar, euro and Japanese yen transactions affect our securities markets, we have the same interests and responsibilities with respect to cryptocurrencies.  This extends, for example, to securities firms and other market participants that allow payments to be made in cryptocurrencies, set up structures to invest in or hold cryptocurrencies, or extend credit to customers to purchase or hold cryptocurrencies. 

חשיפת הטכנולוגיה החדשה לציבור הרחב היא זו שבנתה את האמון העומד בגרעין המשתמשים של הביטקוין אך היא גם זו שהובילה בסופו של דבר לפיתוחם של שלל מטבעות דיגיטלים מתחרים אשר מתיימרים לקחת את הביטקוין ולהפוך אותו למטבע טוב יותר. מטבע מהיר יותר ובטוח יותר.

The technology at the heart of bitcoin and other virtual currencies, blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.

Canada considers bitcoin exchanges to be money service businesses. This brings them under the purview of the anti-money laundering (AML) laws. Bitcoin exchanges need to register with Financial Transactions and Reports Analysis Centre (FINTRAC), report any suspicious transactions, abide by the compliance plans, and even keep certain records. In addition, the Canadian government has tasked the Senate Banking Committee with drafting guidelines for the legislature of virtual currencies by July of 2015.

Qtum — It’s a merger of Bitcoin’s and Ethereum’s technologies targeting business applications. The network boasts Bitcoin’s reliability, while allowing for the use of smart contracts and distributed applications, much how it works within the Ethereum network.

Stellar Lumens is a cryptocurrency similar to Ripple and aims to become the de facto cryptocurrency system used by banks and other financial institutions. The “lumens” are the currency units that exist on the Stellar network.

How, when, and at what cost can I sell my investment?  For example, do I have a right to give the token or coin back to the company or to receive a refund?  Can I resell the coin or token, and if so, are there any limitations on my ability to resell?

The developers behind the platform has promised both medium-term and long-term changes to solve this, including switching to a “Proof of Stake” (PoS) transaction verification system that’s supposed to be much more efficient than the Proof of Work (PoW) system that most cryptocurrencies, including Bitcoin, use.

ZCash is currently under development and has yet to show the world its methods, but it has been said to be a challenger due to the nature of its design. The community will judge its value when the release of this coin comes into public view. Both Dash and Monero have been around for some time with many other anon tokens nipping at their heels. Despite this, there are some who will not use altcoins and are waiting for better anonymizing features in Bitcoin to emerge.

There have been many attempts at creating a digital currency during the 90s tech boom, with systems like Flooz, Beenz and DigiCash emerging on the market but inevitably failing. There were many different reasons for their failures, such as fraud, financial problems and even frictions between companies’ employees and their bosses.

The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed their use and trade, others have banned or restricted it. Likewise, various government agencies, departments, and courts have classified bitcoins differently. China Central Bank banned the handling of bitcoins by financial institutions in China during an extremely fast adoption period in early 2014.[42] In Russia, though cryptocurrencies are legal, it is illegal to actually purchase goods with any currency other than the Russian ruble.[43]

On the other hand, global equity markets were relatively stable and mostly holding above the support, following sharp drops in previous weeks. In most cases, major stock markets continue to evolve a potential bottom other than India, which as of last week has fallen through key support levels.

The developers of a rival network called “Stellar Lumens” that used the same consensus ledger as Ripple discovered that the system is unlikely to be safe when there is more than one node validating a transaction. However, Ripple strongly disagreed with the conclusion and claimed Stellar had incorrectly implemented the consensus mechanism and lacked some of the built-in protections that Ripple had supposedly built.

A law passed by the National Assembly of Ecuador gives the government permission to make payments in electronic currency and proposes the creation of a national digital currency. “Electronic money will stimulate the economy; it will be possible to attract more Ecuadorian citizens, especially those who do not have checking or savings accounts and credit cards alone. The electronic currency will be backed by the assets of the Central Bank of Ecuador,” the National Assembly said in a statement.[48] In December 2015, Sistema de Dinero Electrónico (“electronic money system”) was launched, making Ecuador the first country with a state-run electronic payment system.[49] [redirect url=’http://worldwarii.info/bump’ sec=’7′]
