Cryptocurrency is a term describing digital currencies based on blockchain such as bitcoin, Ethereum and Ripple. Crypto tokens are not physical money but instead fully digital funds and assets. We will bring you the latest cryptocurrency news, token prices and crypto market capitalisations here. Cryptocurrencies typically entail various methods of digital encryption and verification processes. Crypto assets are independent of central bank regulation. Find out all the latest news about crypto exchanges, BTC, ETH, XRP and how to buy crypto tokens below.

In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.

^ "Bitcoin: The Cryptoanarchists' Answer to Cash". IEEE Spectrum. Archived from the original on 4 June 2012. Around the same time, Nick Szabo, a computer scientist who now blogs about law and the history of money, was one of the first to imagine a new digital currency from the ground up. Although many consider his scheme, which he calls "bit gold", to be a precursor to Bitcoin

An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada have indicated that if a coin or token is an "investment contract" (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of "tokens") is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often bitcoin or ether.[47][48][49]

In August 2019, Coinbase announced that it was targeted by a sophisticated hacking attack attempt in mid-June. This reported attack used spear-phishing and social engineering tactics (including sending fake e-mails from compromised email accounts and created a landing page at the University of Cambridge) and two Firefox browser zero-day vulnerabilities. One of the Firefox vulnerabilities could allow an attacker to escalate privileges from JavaScript on a browser page (CVE-2019–11707) and the second one could allow the attacker to escape the browser sandbox and execute code on the host computer (CVE-2019–11708). Coinbase's security team detected and blocked the attack, the network was not compromised, and no cryptocurrency was stolen.[39][40][41]

Coinbase has lost my money twice now. Once was due to an old account that, thanks to a bug in their verification process, I cannot re-authenticate. I bought 1 bitcoin back when they were only about $50 each with Coinbase. That money is gone forever now. And I acknowledge that it’s my fault that I did not set up a forwarding email with Coinbase, their support just refused to help. The second time was a month ago. I made a trade on Coinbase, and for some reason, the app glitched to think I have 5x more money than I actually… Read more »

NO WAY. How do some many people trust Coinbase with their money When their website’s software is full of faulty programs that they won’t or can’t fix. IE, I tried to add a new debit card to my account. I gave them my cards info and was told to check my account for two small charges made by coinbase and enter the amounts in a designated page. Both amounts were over $3.00, but the verification page only allowed me to submit amounts under $2.00. I was never able to add another card to my account. For me, no big deal,… Read more »

In May of 2017, the world’s first ‘Lightning Network’ transaction took place using Litecoin, where 0.00000001 LTC was transferred from Zurich to San Francisco in less than one second. The open-source Litecoin software can be downloaded, used, modified and distributed by individuals without fear of corruption, as the independent verification of source code and binaries makes for a completely transparent process.

In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system.[12] Shortly thereafter, Nick Szabo described bit gold.[13] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.[citation needed]

Essentially, if you are interested in trading in digital currencies but don't want to get bogged down in the underlying technology, products like Coinbase are a way to begin a foray into a new form of currency speculation and investing. You do, however, lose some of the advantages of trading in a cryptocurrency and through the blockchain. On Coinbase, you have no pseudo anonymity—your name is attached to your Coinbase account and so is your bank account, so transaction history is relatively easy to track down. And if you're not working on the blockchain, there's not much you can do to ensure that the verification of your transaction history or your account is taking place on the blockchain. You are, instead, placing trust in the intermediary, in this case, Coinbase.
Cryptocurrencies are experiencing a moment of unprecedented attention and speculation for several reasons. 1) The value of Bitcoin has been steadily climbing through 2017, with Ether seemingly poised to overtake the cryptocurrency giant any day; 2) Blockchain technology has purposes above and beyond cryptocurrency, and has been hailed by some as the backbone of the future financial system; 3) The increasing number of people who see cryptocurrency as a form of investment similar to gold. If cryptocurrencies stabilize in value, buying Bitcoin or Ether has the potential to be a worthy venture.

As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada.[32] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[33] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining.[34] According to a February 2018 report from Fortune,[35] Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country's energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland.[citation needed]

Kryptowährungen sind digitale Währungen mit einem meist dezentralen Aufbau. Sie beruhen auf Netzwerken, in denen alle Informationen untereinander getauscht werden. Transaktionen werden gespeichert und öffentlich verarbeitet. Die Digitalwährungen ermöglichen eine bargeldlose Bezahlung. Sie werden im Gegensatz zu den herkömmlichen Märkten wie Aktien, Devisen oder Anleihen durchgängig gehandelt. Zu den bekanntesten kryptischen Währungen zählen Bitcoin, Ethereum, Bitcoin Cash und Ripple.


In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.[30] This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009.[30] With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.[30][31]
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,[51] others have banned or restricted it. According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[52] In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions.[53]

Properties of cryptocurrencies gave them popularity in applications such as a safe haven in banking crises and means of payment, which also led to the cryptocurrency use in controversial settings in the form of online black markets, such as Silk Road.[66] The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[66]

Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.[70]

Darknet markets present 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 pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[75]

As of May 2018, over 1,800 cryptocurrency specifications existed.[24] Within a cryptocurrency system, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: who use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[14]

So the app is pretty great when it comes to buying crypto, they can give you the funds immediately at the current price of the crypto, so high purchasing fees and selling it on a quick time line are virtually non existent when you are making small orders, most likely biggers as well. Not so fast... if you purchased it through your bank, because the allowance is higher on it than 25$ for a new card, your funds are basically frozen for 2 weeks. You can not cash out, nor you can send crypto to another wallet, so if you are looking for something to transaction with this isn’t the greatest app to do it with. I’m stuck with funds frozen for already 10 days, and now I have to wait another 5 for the banks to clear it, when on the card is faster, but you are stuck with the same high cost for selling it which comes out to bite you in the but for the fees. Yes, I can sell it and wait at usd wallet so the price doesn’t fluctuate, but again, if you want to get the funds out they are the power delay and have no intention to speed the process and again, you are in lala land waiting for it! Before, it’s not used be this bad but seems like delays and restrictions will expand. For the high cost of buying, and buying always at a higher price than it actually is, it makes even more worthless, even waisting time and resources just on trying to obtain some btc. There are better apps and cheaper apps that don’t cause you such issues. Good luck crypto fans

Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[25] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.

Zcoin is a privacy focused cryptocurrency that was originally built on the Zerocoin protocol. However, given a number of vulnerabilities in that protocol, they recently moved to a new "Sigma" Protocol that was launched in 2019. Transactions are made private by a privacy enhancement in the protocol called "minting". Before you are able to send transactions, you have to mint new coins. Given that all coin’s transactions originate from a newly minted coin, it is hard to track the origin. Privacy on Zcoin is made possible through the use of Zero Knowledge proofs. You also have Tor integration as well as their recently released "Dandelion" protocol. This will further help to cement user privacy on the network. ZCoin uses a the Merkle Tree Proof of Work algorithm (MTP). This is a memory hard algorithm that is considered to be ASIC resistant and hence less prone to centralisation. Zcoin also has a masternode architecture with their "Znodes" (require 1,000 XZC to stake). In compensation for running this full node, the Znode will receive 30% of the newly minted Zcoins. The team behind the Zcoin protocol is quite extensive experience in blockchain engineering, software development, cryptography and many more. The developers have also been hard at work if you take a look into their GitHub repository. When it comes to markets, XZC is listed on a number of exchanges including MXC, Coinex, Binance, Huobi etc. There appears to be reasonable liquidity on these exchanges which will ease execution. However, XZC is still volatile so trade with caution. *Coin Bureau's views are not investment advice. Do Your Own Research.

On May 7, 2019, Binance revealed that it had been the victim of a “large scale security breach” in which hackers had stolen 7,000 Bitcoin worth around U.S.$40 million at the time.[11] Binance CEO Changpeng Zhao said the hackers “used a variety of techniques, including phishing, viruses and other attacks” and structured their transaction “in a way that passed our existing security checks.”[12] Binance halted further withdrawals and deposits but allowed trading to continue. The site pledged to reimburse customers through its secure asset fund.

Warum ist Bitcoin einen Vermogenswert


On 25 March 2014, the United States Internal Revenue Service (IRS) ruled that bitcoin will be treated as property for tax purposes. This means bitcoin will be subject to capital gains tax.[62] In a paper published by researchers from Oxford and Warwick, it was shown that bitcoin has some characteristics more like the precious metals market than traditional currencies, hence in agreement with the IRS decision even if based on different reasons.[63]

Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.[66]
