“Cryptocurrencies ירידה במחיר -ידע Cryptocurrency”

Cryptocurrencies.  Speaking broadly, cryptocurrencies purport to be items of inherent value (similar, for instance, to cash or gold) that are designed to enable purchases, sales and other financial transactions.  They are intended to provide many of the same functions as long-established currencies such as the U.S. dollar, euro or Japanese yen but do not have the backing of a government or other body.  Although the design and maintenance of cryptocurrencies differ, proponents of cryptocurrencies highlight various potential benefits and features of them, including (1) the ability to make transfers without an intermediary and without geographic limitation, (2) finality of settlement, (3) lower transaction costs compared to other forms of payment and (4) the ability to publicly verify transactions.  Other often-touted features of cryptocurrencies include personal anonymity and the absence of government regulation or oversight.  Critics of cryptocurrencies note that these features may facilitate illicit trading and financial transactions, and that some of the purported beneficial features may not prove to be available in practice.

DasCoin’s proof-of-value distribution protocol prevents wealth concentration within the currency and assures a much wider and more equitable distribution of coins, which enhances the stability of the system.

Litecoin LTC 2011-10-07 Low ~84,000,000 Scrypt PoW Originally meant to be a CPU-friendly “silver” to Bitcoin’s “gold”, the early SCRYPT parameters, it was discovered later, led directly to GPU, and then ASIC-mining almost from the start. litecoin.org

 מטבעות מבוזרים הם מטבעות וירטואלים (דיגיטלים). מטבע זה מוגן מפני זיוף. לא ניתן להעתיק אותו כי הוא מכיל מידע מוצפן. לכן, התשובה לשאלה של “מטבע וירטואלי מבוזר – מה זה?” תשמע כמו “זה כסף אלקטרוני.” אבל זה לא כסף אלקטרוני שאנחנו רגילים אליו

On November 21, 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USTD from their primary wallet.[59] The company has ‘tagged’ the stolen currency, hoping to ‘lock’ them in the hacker’s wallet (making them unspendable). Tether indicates that it is building a core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.

All of those factors make mining cryptocurrencies an extremely competitive arms race that rewards early adopters. However, depending on where you live, profits made from mining can be subject to taxation and Money Transmitting regulations. In the US, the FinCEN has issued a guidance, according to which mining of cryptocurrencies and exchanging them for flat currencies may be considered money transmitting. This means that miners might need to comply with special laws and regulations dealing with this type of activities.

The Bank of Canada teamed up with the nation’s five largest banks — and the blockchain consulting firm R3 — for what was known as Project Jasper. In a simulation run in 2016, the central bank issued CAD-Coins onto a blockchain similar Ethereum.[44] The banks used the CAD-Coins to exchange money the way they do at the end of each day to settle their master accounts.[44]

Zcash transactions are untraceable because it uses encryption called zk-SNARK developed by the startup’s team. The transaction metadata within the network is encrypted, and zk-SNARKs are utilized to stop double spends. 

While a traditional stock is a legal claim backed up by regulators and governments, then, the tokens sold in an ICO are deeply embedded in the blockchain software their sale helps create. Knowledgeable tech investors are excited by this because, along with the open-source nature of much of the software, it means that ICO-funded projects can, like Bitcoin itself, outlast any single founder or legal entity. In a 2016 blog post, Joel Monegro, of the venture capital fund Union Square Ventures, compared owning a blockchain-based asset to owning a piece of digital infrastructure as fundamental as the internet’s TCP/IP protocol.

The fact that bitcoin can be anonymously used to conduct transactions between any account holders, anywhere and anytime across the globe, makes it attractive to criminal elements. They may use bitcoins to buy or sell illegal goods like drugs or weapons. Most countries have not clearly made determinations on the legality of bitcoin, preferring instead to take a wait-and-see approach. Some countries have indirectly assented to the legal usage of bitcoins by enacting some regulatory oversight. However, bitcoin is never legally acceptable as a substitute for a country’s legal tender.

In recent years we have seen a drastic expansion in the types of data being used to evaluate credit-worthiness. This opens up new opportunities to deliver services to underserved populations, ideally services that are catered to their specific needs and lifestyles. However, much of this data are locked-in to the applications in which they were generated, making it nearly impossible for consumers to leverage it to access a broader set of opportunities. In this project, we develop a toolkit that enables consumers in East Africa to knit together a credit identity from across a variety of data silos. We will then develop a blockchain-enabled back end infrastructure that empowers our target users to leverage the data generated from these devices in an open marketplace of credit lenders, in a “credit bureau of the 21st century.”

מה זה ביטקוין?  מה זה ביטקוין במילים פשוטות? זהו דור חדש של מטבע דיגיטלי מבוזר, שנוצר ופועל רק באינטרנט. אף אחד לא שולט בו, הנפקת מטבע מתרחשת דרך העבודה של מיליוני מחשבים  ברחבי העולם באמצעות תוכנה לחישוב אלגוריתמים מתמטיים. זוהי המהות של ביטקוין

In order to remain equally interchangeable, units of cryptocurrency must be unlinked from their history so that one unit is as good as any other unit. Zcash brings fungibility to cryptocurrency by unlinking shielded coins from their history on the blockchain.

הערת מערכת: ניתן לרכוש את האלטים הפופולריים כגון איתריום, מונרו, לייטקוין וכו’ גם במסחר ישיר מול הדולר באתרי מסחר כגון BitFinex אך כדי להפקיד דולרים באתרים הנ”ל נדרש חשבון בנק בינלאומי, העברות בנקאיות וכו’ מה שיאריך את התהליך ויסרבלו.

According to the OmiseGO developers, “anyone will be able to conduct financial transactions such as payments, remittances, payroll deposit, B2B commerce, supply-chain finance, loyalty programs, asset management and trading, and other on-demand services, in a completely decentralized and inexpensive way.”< בשנת 2014 הושמעה באמצעי התקשורת ביקורת על עתידו של הביטקוין, שהחריפה במיוחד לאחר נפילת הבורסה הווירטואלית Mt. Gox, שהייתה בורסת הביטקוין הגדולה והחשובה בעולם, אשר נפגעה מפריצה ושוד של כ-850,000 ביטקוין ולבסוף הגיעה לפשיטת רגל ונסגרה.[34] תגובה אחרת למשבר הייתה של ממשלת יפן, שהודיעה בפברואר 2014 כי היא תפעל להגדרת הליכים פורמליים לבצוע העברות מטבע ביטקוין ובכלל זה גם תבחן את היבטי המיסוי של הביטקוין. Initial Coin Offerings.  Coinciding with the substantial growth in cryptocurrencies, companies and individuals increasingly have been using initial coin offerings to raise capital for their businesses and projects.  Typically these offerings involve the opportunity for individual investors to exchange currency such as U.S. dollars or cryptocurrencies in return for a digital asset labeled as a coin or token.  Great course, a very broad and in-depth overview of concepts surrounding cryptocurrencies and Bitcoin in particular. Would be great to have an update of course; perhaps once the ICO craze is over? (-: “We could remove the ability for billionaires and advertisers to threaten what people write anymore,” Bustillos says, because a copy of the archives would be held on the computer of everyone who became a part of the platform. The Popula founder says she is working on incorporating a project called the Interplanetary File System, an attempt to build a massively distributed network of computers to store documents. Just because "everyone" agrees on any given topic or thing doesn't mean is the CORRECT one. You should study and understand some history. Look at executive order 6102; AKA Gold Act of 1933. The US government literally STOLE gold from people under the pretext that it was for the "best". It's now known that J.P. Morgan Chase was influential in causing the market crash of early 1907, as most banksters quietly existed the market before the crash. The main promise of Ethereum is that it’s a Turing-complete “programmable blockchain” that allows developers to build all sorts of distributed apps and technologies that wouldn’t easily work on top of Bitcoin (as it stands today). Ethereum has recently faced some scaling issues as the number of companies launching an “Initial Coin Offering” (ICO) has boomed. The network has been bogged down for many hours or even days at a time due to a handful of popular projects launching their own ICO to raise funds. בשנת 2013 החלו האתרים Reddit ו-Mega להציע את שירותיהם גם תמורת ביטקוין.[30] באפריל אותה שנה הגיע ערך המטבע ל-100$ לביטקוין אחד.[31][32] באוקטובר 2013 נסגר בידי ה-FBI אתר מכירת הסמים הגדול ביותר באינטרנט, "דרך המשי", אשר פעל בדארקנט ושכל העסקאות בו נעשו באמצעות ביטקוין. במהלך הסגירה נתפסו כ-26 אלף ביטקוינים בשווי 3.6 מיליון דולר, על אף שעל פי הערכות זהו רק חלק קטן מהשווי הכולל של הביטקוינים המצויים ברשותו של מקים האתר, רוס ויליאם אולבריכט.[33] בסרטון זה, ד"ר רוז'ה מתראיינת ומספרת על חייה הפרטיים, חזונה לגבי המטבע ועתיד התשלומים, הצלחתה כאישה בעולם של גברים , על בעלי חיים ועוד. ראיון מעורר השראה והעצמה נשית לגבי הבאת הביטוי המיוחד של נשים בעולם. הסרטון עם כתוביות בעיברית ומומלץ לצפייה גם לגברים (:   Technically, it's a challenge to have fungibility in a shared blockchain, yet money requires fungibility. It's exciting to see the Zcash team working toward adding real fungibility to blockchains and with the strength and talent of this team, this is only the tip of the iceberg. Unlike IPOs, however, ICOs are catnip for scammers. They are not formally regulated by any financial authority, and exist in an ecosystem with few checks and balances. OneCoin loudly trumpeted its use of blockchain technology, but holes in that claim were visible long before international law enforcement took notice. Whereas Gnosis had experienced engineers, endorsements from known experts, and an operational version of their software, OneCoin was led and promoted by known fraudsters waving fake credentials. According to a respected blockchain engineer who was offered a position as OneCoin’s Chief Technology Officer, OneCoin’s “blockchain” consisted of little more than a glorified Excel spreadsheet and a fugazi portal that displayed demonstrably fake transactions. אחד הנתונים המעניינים ביותר את מי שבוחן את עולם הביטקוין, הוא שער ההמרה בינו לבין מטבעות מסורתיים. השער מבטא ...בצורה תמציתית את היקף התופעה ואת גודל הכלכלה הדיגיטלית החדשה העומדת מאחורי ביטקוין. בנוסף, עבור מי שהשקיע במטבע, לתמורות בשער יש השפעה ישירה על הכיס.
