All about cryptocurrency
Proof of work is one way of incentivizing users to help maintain an accurate historical record of who owns what on a blockchain network. Bitcoin uses proof of work, which makes this method an important part of the crypto conversation https://aus-casino-gambling.com. Blockchains rely on users to collate and submit blocks of recent transactions for inclusion in the ledger, and Bitcoin’s protocol rewards them for doing so successfully. This process is known as mining.
Ethereum’s Ether is consistently the second-largest cryptocurrency. Ethereum serves as a platform for other cryptocurrencies besides Ether, and offering decentralized applications to other token creators ensures that Ether consistently retains greater value than those other tokens. Most cryptocurrencies rely on the decentralized applications provided by Ethereum.
However, it’s important to note that to some, cryptocurrencies aren’t investments at all. Bitcoin enthusiasts, for example, hail it as a much-improved monetary system over our current one and would prefer we spend and accept it as everyday payment. One common refrain — “one Bitcoin is one Bitcoin” — underscores the view that Bitcoin shouldn’t be measured in USD, but rather by the value it brings as a new monetary system.

Cryptocurrency is produced by an entire cryptocurrency system collectively, at a rate that is defined when the system is created and that is publicly stated. In centralized banking and economic systems such as the US Federal Reserve System, corporate boards or governments control the supply of currency. In the case of cryptocurrency, companies or governments cannot produce new units and have not so far provided backing for other firms, banks, or corporate entities that hold asset value measured in it. The underlying technical system upon which cryptocurrencies are based was created by Satoshi Nakamoto.
Many cryptocurrency projects are untested, and blockchain technology in general has yet to gain wide adoption. If the underlying idea behind cryptocurrency does not reach its potential, long-term investors may never see the returns they hoped for.
If you only want to buy cryptocurrency as an investment, you may be able to do so through your brokerage. For example, Robinhood allows users to invest in bitcoin and other cryptocurrencies, although you cannot withdraw them from the platform for purchases. In addition, there are several crypto ETFs that provide exposure to the crypto asset class without requiring the investors to maintain their own wallets. For instance, as of May 2024, investors may choose to hold Bitcoin futures ETF shares. The SEC has also approved the listing and trading of Ether spot shares.
Despite these risks, cryptocurrencies have seen a significant price leap, with the total market capitalization rising to about $2.4 trillion. Despite the asset’s speculative nature, some have created substantial fortunes by taking on the risk of investing in early-stage cryptocurrencies.
Cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH) represent a form of digital currency that does not rely upon intermediaries like banks to verify transactions. Instead, cryptocurrencies are created and maintained on distributed ledgers, or blockchains.
What is cryptocurrency
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.
The EU defines crypto assets as “a digital representation of a value or of a right that is able to be transferred and stored electronically using distributed ledger technology or similar technology.” The EU regulation Markets in Crypto-Assets (MiCA) covering asset-referenced tokens (ARTs) and electronic money tokens (EMTs) (also known as stablecoins) came into force on 30 June 2024. As of 17 January 2025, the European Securities and Markets Authority (ESMA) issued guidance to crypto-asset service providers (CASPs) allowing them to maintain crypto-asset services for non-compliant ARTs and EMTs until the end of March 2025.
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. 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.
Bitcoin was initially developed primarily to be a form of payment that isn’t controlled or distributed by a central bank. While financial institutions have traditionally been necessary to verify that a payment has been processed successfully, Bitcoin accomplishes this securely, without that central authority.
Although cryptocurrencies are considered a form of money, the Internal Revenue Service (IRS) treats them as financial assets or property for tax purposes. And, as with most other investments, if you reap capital gains selling or trading cryptocurrencies, the government wants a piece of the profits. How exactly the IRS taxes digital assets—either as capital gains or ordinary income—depends on how long the taxpayer held the cryptocurrency and how they used it.
On 23 March 2023, the SEC issued an alert to investors stating that firms offering crypto asset securities might not be complying with US laws. The SEC argued that unregistered offerings of crypto asset securities might not include important information.
