Cryptocurrency. What is Crypto?

​Cryptocurrency, often abbreviated as "crypto," is a type of digital or virtual currency that uses cryptographic techniques to secure transactions and control the creation of additional units. Unlike traditional fiat currencies issued by governments, cryptocurrencies operate on decentralized systems based on blockchain technology—a distributed ledger enforced by a network of computers (nodes). ​

Key Characteristics of Cryptocurrencies:

1. Decentralization: Cryptocurrencies are typically not controlled by any central authority, such as a government or financial institution. This decentralization is achieved through blockchain technology, which ensures that all transactions are transparent and immutable. ​

2. Cryptography: The use of cryptographic techniques ensures the security and integrity of transactions, making it difficult for unauthorized parties to alter transaction data. ​PwC

3. Digital Nature: Cryptocurrencies exist solely in digital form and do not have a physical counterpart like coins or banknotes. They are stored in digital wallets, which can be software-based or hardware-based. ​

4. Global Transactions: Cryptocurrencies enable peer-to-peer transactions across borders without the need for intermediaries, allowing for faster and potentially lower-cost transfers compared to traditional banking systems. ​

Popular Cryptocurrencies:

• Bitcoin (BTC): Launched in 2009, Bitcoin is the first and most well-known cryptocurrency, often referred to as digital gold due to its limited supply and store of value properties. ​

• Ethereum (ETH): Introduced in 2015, Ethereum is a decentralized platform that enables smart contracts and decentralized applications (dApps) to be built and run without any downtime, fraud, or interference. ​

• Ripple (XRP): Designed for digital payment processing, Ripple facilitates real-time, cross-border payments for banks and financial institutions. ​

Recent Developments:

As of March 7, 2025, the cryptocurrency landscape has seen significant developments. Notably, President Donald Trump signed an executive order establishing a government bitcoin reserve, signaling a move towards mainstream acceptance of cryptocurrencies. This reserve comprises approximately 200,000 bitcoins seized in various proceedings and is intended to serve as a store of value. Additionally, a "Crypto Summit" was hosted at the White House to discuss the integration of cryptocurrencies into the financial system. ​

Furthermore, Bitcoin's value has surged, recently surpassing the $100,000 mark, driven by market optimism and expectations of favorable regulatory changes under the current administration. ​
