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. Cryptocurrencies are systems that allow for secure payments online which are denominated in terms of virtual "tokens," which are represented by ledger entries internal to the system.

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 by an individual or group known by the pseudonym " Satoshi Nakamoto. 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.

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. 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 arrest and prosecute criminals.

More privacy-oriented coins do exist, however, such as Dash , Monero, or ZCash , which are far more difficult to trace.

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 an 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. 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. 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. 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 year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of "coins" stolen. Nonetheless, many observers see potential advantages in cryptocurrencies, like the possibility of preserving value against inflation and facilitating exchange while being easier to transport and divide than precious metals and existing outside the influence of central banks and governments.

The bitcoin payment system is purely peer-to-peer, meaning that users are able to send and receive payments to or from anyone on the network around the world without requiring approval from any external source or authority. While it is considered standard among cryptocurrency exchanges to charge so-called "maker" and "taker" fees , as well as occasional deposit and withdrawal fees, bitcoin users are not subject to the litany of traditional banking fees associated with fiat currencies.

This means no account maintenance or minimum balance fees, no overdraft charges and no returned deposit fees, among many others.

Standard wire transfers and foreign purchases typically involve fees and exchange costs. Since bitcoin transactions have no intermediary institutions or government involvement, the costs of transacting are kept very low.
