What Is a Cryptocurrency?
A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.
KEY TAKEAWAYS
A cryptocurrency is a new form of digital asset based on a network that is distributed across a large number of computers. This decentralized structure allows them to exist outside the control of governments and central authorities.
The word “cryptocurrency” is derived from the encryption techniques which are used to secure the network.
Blockchains, which are organizational methods for ensuring the integrity of transactional data, is an essential component of many cryptocurrencies.
Many experts believe that blockchain and related technology will disrupt many industries, including finance and law.
Cryptocurrencies face criticism for a number of reasons, including their use for illegal activities, exchange rate volatility, and vulnerabilities of the infrastructure underlying them. However, they also have been praised for their portability, divisibility, inflation resistance, and transparency.
Understanding Cryptocurrencies
Cryptocurrencies are systems that allow for the secure payments online which are denominated in terms of virtual "tokens," which are represented by ledger entries internal to the system. "Crypto" refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.
Types of Cryptocurrency
The first blockchain-based cryptocurrency was Bitcoin, which still remains the most popular and most valuable. Today, there are thousands of alternate cryptocurrencies with various functions and specifications. Some of these are clones or forks of Bitcoin, while others are new currencies that were built from scratch.
Bitcoin was launched in 2009 by an individual or group known by the pseudonym "Satoshi Nakamoto."1 As of Nov. 2019, there were over 18 million bitcoins in circulation with a total market value of around $146 billion.2
Some of the competing cryptocurrencies spawned by Bitcoin’s success, known as "altcoins," include Litecoin, Peercoin, and Namecoin, as well as Ethereum, Cardano, and EOS. Today, the aggregate value of all the cryptocurrencies in existence is around $214 billion—Bitcoin currently represents more than 68% of the total value.3
Some of the cryptography used in cryptocurrency today was originally developed for military applications. At one point, the government wanted to put controls on cryptography similar to the legal restrictions on weapons, but the right for civilians to use cryptography was secured on grounds of freedom of speech.
Special Considerations
Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology, which is used to keep an online ledger of all the transactions that have ever been conducted, thus providing a data structure for this ledger that is quite secure and is shared and agreed upon by the entire network of individual node, or computer maintaining a copy of the ledger. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.
Many experts see blockchain technology as having serious potential for uses like online voting and crowdfunding, and major financial institutions such as JPMorgan Chase (JPM) see the potential to lower transaction costs by streamlining payment processing.4 However, because cryptocurrencies are virtual and are not stored on a central database, a digital cryptocurrency balance can be wiped out by the loss or destruction of a hard drive if a backup copy of the private key does not exist. At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.
Advantages and Disadvantages of Cryptocurrency
Advantages
Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties, without the need for a trusted third party like a bank or credit card company. These transfers are instead secured by the use of public keys and private keys and different forms of incentive systems, like Proof of Work or Proof of Stake.
In modern cryptocurrency systems, a user's "wallet," or account address, has a public key, while the private key is known only to the owner and is used to sign transactions. Fund transfers are completed with minimal processing fees, allowing users to avoid the steep fees charged by banks and financial institutions for wire transfers.
Disadvantages
The semi-anonymous nature of cryptocurrency transactions makes them well-suited for a host of illegal activities, such as money laundering and tax evasion. However, cryptocurrency advocates often highly value their anonymity, citing benefits of privacy like protection for whistleblowers or activists living under repressive governments. Some cryptocurrencies are more private than others.
Bitcoin, for instance, is a relatively poor choice for conducting illegal business online, since the forensic analysis of the Bitcoin blockchain has helped authorities to arrest and prosecute criminals. More privacy-oriented coins do exist, however, such as Dash, Monero, or ZCash, which are far more difficult to trace.
Criticism of Cryptocurrency
Since market prices for cryptocurrencies are based on supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can fluctuate widely, since the design of many cryptocurrencies ensures a high degree of scarcity.
Bitcoin has experienced some rapid surges and collapses in value, climbing as high as $19,000 per Bitcoin in Dec. of 2017 before dropping to around $7,000 in the following months.2 Cryptocurrencies are thus considered by some economists to be a short-lived fad or speculative bubble.
There is concern that cryptocurrencies like Bitcoin are not rooted in any material goods. Some research, however, has identified that the cost of producing a Bitcoin, which requires an increasingly large amount of energy, is directly related to its market price.
Cryptocurrency blockchains are highly secure, but other aspects of a cryptocurrency ecosystem, including exchanges and wallets, are not immune to the threat of hacking. In Bitcoin's 10-year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of "coins" stolen.5
Nonetheless, many observers see potential advantages in cryptocurrencies, like the possibility of preserving value against inflation and facilitating exchange while being more easy to transport and divide than precious metals and existing outside the influence of central banks and governments.

The type, amount and verification can be different for each blockchain. It is a matter of the blockchain’s protocol – or rules for what is and is not a valid transaction, or a valid creation of a new block. The process of verification can be tailored for each blockchain. Any needed rules and incentives can be created when enough nodes arrive at a consensus on how transactions ought to be verified.security bitcoin hd bitcoin daemon bitcoin
Typically, the higher the gas price the sender is willing to pay, the greater the value the miner derives from the transaction. Thus, the more likely miners will be to select it. In this way, miners are free to choose which transactions they want to validate or ignore. In order to guide senders on what gas price to set, miners have the option of advertising the minimum gas price for which they will execute transactions.a complete financial system that facilitates the transfer and custody of bitcoin, a new digitalWhat Is Bitcoin?credit bitcoin

Most individuals who own and use Bitcoin have not acquired their tokens through mining operations. Rather, they buy and sell Bitcoin and other digital currencies on any of a number of popular online markets known as Bitcoin exchanges. Bitcoin exchanges are entirely digital and, as with any virtual system, are at risk from hackers, malware, and operational glitches. If a thief gains access to a Bitcoin owner's computer hard drive and steals his private encryption key, he could transfer the stolen Bitcoins to another account. (Users can prevent this only if bitcoins are stored on a computer which is not connected to the internet, or else by choosing to use a paper wallet – printing out the Bitcoin private keys and addresses, and not keeping them on a computer at all.) Hackers can also target Bitcoin exchanges, gaining access to thousands of accounts and digital wallets where bitcoins are stored. One especially notorious hacking incident took place in 2014, when Mt. Gox, a Bitcoin exchange in Japan, was forced to close down after millions of dollars worth of bitcoins were stolen.11Monero is the leading cryptocurrency with a focus on private and censorship-resistant transactions.air bitcoin bitcoin frog bitcoin two ethereum токены bitcoin nonce bitcoin покупка bitcoin sberbank bitcoin easy bitcoin коллектор

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.bitcoin red electrum bitcoin usa bitcoin обменники bitcoin bitcoin cash халява bitcoin купить bitcoin ethereum настройка casper ethereum bitcoin калькулятор token bitcoin invest bitcoin bitcoin разделился segwit bitcoin сборщик bitcoin dance bitcoin ethereum перспективы фонд ethereum заработок bitcoin
