A cryptocurrency wallet stores the public and private "keys" or "addresses" which can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency.
With the public key, it is possible for others to send currency to the wallet. Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys or "addresses".
Still, cryptocurrency exchanges are often required by law to collect the personal information of their users. Additions such as Zerocoin , Zerocash and CryptoNote have been suggested, which would allow for additional anonymity and fungibility.
Most cryptocurrency tokens are fungible and interchangeable. However, unique non-fungible tokens also exist. Such tokens can serve as assets in games like CryptoKitties.
Cryptocurrencies are used primarily outside existing banking and governmental institutions and are exchanged over the Internet.
Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction.
The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest.
Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.
For ether , transaction fees differ by computational complexity, bandwidth use, and storage needs, while bitcoin transaction fees differ by transaction size and whether the transaction uses SegWit.
Cryptocurrency exchanges allow customers to trade cryptocurrencies for other assets, such as conventional fiat money , or to trade between different digital currencies.
Atomic swaps are a mechanism where one cryptocurrency can be exchanged directly for another cryptocurrency, without the need for a trusted third party such as an exchange.
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. 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.
According to PricewaterhouseCoopers , four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations.
The Swiss regulatory agency FINMA stated that it would take a "balanced approach" to ICO projects and would allow "legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system.
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.
According to the Library of Congress , an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Various government agencies, departments, and courts have classified bitcoin differently.
China Central Bank banned the handling of bitcoins by financial institutions in China in early In Russia, though cryptocurrencies are legal, it is illegal to actually purchase goods with any currency other than the Russian ruble.
Cryptocurrencies are a potential tool to evade economic sanctions for example against Russia , Iran , or Venezuela. In April , Russian and Iranian economic representatives met to discuss how to bypass the global SWIFT system through decentralized blockchain technology.
The Japanese platform Line and the Russian platform Yandex have similar prohibitions. This means bitcoin will be subject to capital gains tax.
As the popularity of and demand for online currencies has increased since the inception of bitcoin in ,  so have concerns that such an unregulated person to person global economy that cryptocurrencies offer may become a threat to society.
Concerns abound that altcoins may become tools for anonymous web criminals. Cryptocurrency networks display a lack of regulation that has been criticized as enabling criminals who seek to evade taxes and launder money.
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.
Systems of anonymity that most cryptocurrencies offer can also serve as a simpler means to launder money. Rather than laundering money through an intricate net of financial actors and offshore bank accounts, laundering money through altcoins can be achieved through anonymous transactions.
Gox , declared bankruptcy. Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in , acknowledged in a plea agreement that the companies were part of a pyramid scheme , and pleaded guilty to wire fraud in Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.
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.
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, to 32, 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. This type of ambiguous classification puts pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.
The law effectively prohibits the use of commodities such as cryptocurrencies and gold as currencies. Bank Indonesia has emphasized the prohibition on using cryptocurrency assets as a medium of exchange in Indonesia.
Cryptocurrencies have been compared to Ponzi schemes , pyramid schemes  and economic bubbles ,  such as housing market bubbles.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.
An enormous amount of energy goes into proof-of-work cryptocurrency mining, although cryptocurrency proponents claim it is important to compare it to the consumption of the traditional financial system.
There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software.
Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media.
This prevents the cryptocurrency from being spent, resulting in its effective removal from the markets. The cryptocurrency community refers to pre-mining, hidden launches, ICO or extreme rewards for the altcoin founders as a deceptive practice.
Paul Krugman , Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last  and links it to Tulip mania.
It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh. The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the bitcoin blockchain.
