What is cryptocurrency
Reeve Collins, Craig Sellars, and Brock Pierce founded Tether, a project initially called realcoin, in 2014. Tether is a stablecoin or cryptocurrency that pegs its value to an external fiat currency. https://quinotizia.com/italian-weekdays/ For example, Tether is pegged to the value of the U.S. dollar at a 1:1 ratio. Tether also supports the euro (EUR), Mexican Peso (MXN), and offshore Chinese yuan (YNH). Like other digital currencies, Tether can move across blockchain networks, but it theoretically offers more pricing stability given its 1:1 peg to a government-issued currency. Tether couples the innovative nature of blockchain with the stability of fiat currencies to reduce volatility.
A cryptocurrency, or crypto, is a digital, encrypted, and decentralized currency that utilizes cryptographic techniques to facilitate secure transactions. In other words, cryptocurrency is like decentralized digital money that people can use to buy services and assets, such as stocks.
bitcoin (BTC) might be losing it’s chokehold on the cryptocurrency market, with the percentage of crypto owners who said BTC was their first coin falling year over year, with 54% saying saying BTC was their first coin in October 2023 compared to 58% in October 2022.
The above is a more general definition that can be used to refer to all types of cryptocurrencies. As you will learn in this guide, some assets may fall into the fringes of this definition, but they are all cryptocurrencies in one form or the other.
DeFi is more dominant on the Ethereum (ETH) network, which is currently the leading smart contract platform and the second-largest blockchain by market capitalization. Ethereum has benefited from a first-mover advantage in this field, being the first public network to support decentralized apps (dApps) since 2015.
Bitcoin cryptocurrency
On October 31, 2008, Nakamoto published Bitcoin’s whitepaper, which described in detail how a peer-to-peer, online currency could be implemented. They proposed to use a decentralized ledger of transactions packaged in batches (called “blocks”) and secured by cryptographic algorithms — the whole system would later be dubbed “blockchain.”
Over the past few decades, consumers have become more curious about their energy consumption and personal effects on climate change. When news stories started swirling regarding the possible negative effects of Bitcoin’s energy consumption, many became concerned about Bitcoin and criticized this energy usage. A report found that each Bitcoin transaction takes 1,173 KW hours of electricity, which can “power the typical American home for six weeks.” Another report calculates that the energy required by Bitcoin annually is more than the annual hourly energy usage of Finland, a country with a population of 5.5 million.

The first chain to launch smart contracts was Ethereum. A smart contract enables multiple scripts to engage with each other using clearly defined rules, to execute on tasks which can become a coded form of a contract. They have revolutionized the digital asset space because they have enabled decentralized exchanges, decentralized finance, ICOs, IDOs and much more. A huge proportion of the value created and stored in cryptocurrency is enabled by smart contracts.
Elke wallet kan worden gebruikt om bitcoin te sturen naar een ander wallet-adres — software, hardware of papier — zolang dat adres specifiek een bitcoinwallet is en niet een wallet ontworpen voor een andere cryptocurrency, zoals Ethereum (ETH), Bitcoin Cash (BCH) of XRP.
How does cryptocurrency work
Ethereum relies on a consensus mechanism called Proof of Stake (PoS), which uses validators that stake tokens on the blockchain and verify transactions before they are added to the chain. The staking process earns validators rewards in the form of ETH — just like how Bitcoin miners get rewarded with BTC for their process.
So far, you’ve learned what cryptocurrencies are and how they work. You also know how to store them and where to trade them. However, understanding cryptocurrency is more than just understanding blockchains and mining. Understanding cryptocurrency is about understanding what those technologies can do for you.
Many cryptocurrencies were created to facilitate work done on the blockchain they are built on. For example, Ethereum’s ether was designed to be used as payment for validating transactions and opening blocks. When the blockchain transitioned to proof-of-stake in September 2022, ether (ETH) inherited an additional duty as the blockchain’s staking mechanism. The XRP Ledger Foundation’s XRP is designed for financial institutions to facilitate transfers between different geographies.
