The same principles apply to Ethereum. “Ether” is the cryptocurrency of the Ethereum blockchain, where developers can build financial apps without the need for a third-party financial institution. https://helpinghandspublications.com/harpercollins-publishing-house/ Developers must use Ether to build and run applications on Ethereum, so theoretically, the more that is built on the Ethereum blockchain, the higher the demand for Ether.
Many banks do not offer virtual currency services themselves and can refuse to do business with virtual currency companies. In 2014, Gareth Murphy, a senior banking officer, suggested that the widespread adoption of cryptocurrencies may lead to too much money being obfuscated, blinding economists who would use such information to better steer the economy. While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen. One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.
On 30 April 2021, the Central Bank of the Republic of Turkey banned the use of cryptocurrencies and cryptoassets for making purchases on the grounds that the use of cryptocurrencies for such payments poses significant transaction risks.

De handel in cryptovaluta kunt u vergelijken met de handel in gewone valuta zoals de Japanse Yen of de Amerikaanse dollar. U bent aan het beleggen en u speculeert op koerswinst. U hoeft dan de opbrengst van de handel niet aan te geven. Dat is anders als u met extra arbeid, dus bovenop uw beleggingsactiviteiten, vaak extra inkomsten verdient. In dat geval moet u de inkomsten wél aangeven. Geeft u deze inkomsten aan als inkomsten uit overig werk of als winst uit onderneming.
The first cryptocurrency was Bitcoin, which was founded in 2009 and remains the best known today. Much of the interest in cryptocurrencies is to trade for profit, with speculators at times driving prices skyward.
In the blockchain, bitcoins are linked to specific addresses that are hashes of a public key. Creating an address involves generating a random private key and then computing the corresponding address. This process is almost instant, but the reverse (finding the private key for a given address) is nearly impossible. : ch. 4 Publishing a bitcoin address does not risk its private key, and it is extremely unlikely to accidentally generate a used key with funds. To use bitcoins, owners need their private key to digitally sign transactions, which are verified by the network using the public key, keeping the private key secret. : ch. 5
Losing a private key means losing access to the bitcoins, with no other proof of ownership accepted by the protocol. For instance, in 2013, a user lost ₿7,500, valued at US$7.5 million, by accidentally discarding a hard drive with the private key. It is estimated that around 20% of all bitcoins are lost. The private key must also be kept secret as its exposure, such as through a data breach, can lead to theft of the associated bitcoins. : ch. 10 As of December 2017 , approximately ₿980,000 had been stolen from cryptocurrency exchanges.
Bitcoin is also used by some governments. For instance, the Iranian government initially opposed cryptocurrencies, but later saw them as an opportunity to circumvent sanctions. Since 2020, Iran has required local bitcoin miners to sell bitcoin to the Central Bank of Iran, allowing the central bank to use it for imports. Some constituent states also accept tax payments in bitcoin, including Colorado (US) and Zug (Switzerland). As of 2023, the US government owned more than $5 billion worth of seized bitcoin.
The domain name bitcoin.org was registered on 18 August 2008. On 31 October 2008, a link to a white paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System was posted to a cryptography mailing list. Nakamoto implemented the bitcoin software as open-source code and released it in January 2009. Nakamoto’s identity remains unknown. According to computer scientist Arvind Narayanan, all individual components of bitcoin originated in earlier academic literature. Nakamoto’s innovation was their complex interplay resulting in the first decentralized, Sybil resistant, Byzantine fault tolerant digital cash system, that would eventually be referred to as the first blockchain. Nakamoto’s paper was not peer reviewed and was initially ignored by academics, who argued that it could not work.

It is important to remember that cryptocurrency transactions do not represent a ‘sending’ of crypto tokens from a person’s mobile phone to someone else’s mobile phone. When sending tokens, a user’s private key signs the transaction and broadcasts it to the blockchain network. The network then includes the transaction to reflect the updated balance in both the sender’s and recipient’s address.
