What is cryptocurrency? The most popular cryptocurrency

May 1, 2023

The use of the word "cryptocurrency" has grown significantly over the past 10 years. People from all over the world are interested in learning what cryptocurrency is and how it works. Let's figure this out together.

The history of cryptocurrency

Such a phenomenon as Bitcoin was a sensation back in 2009. Let's look at the path that cryptocurrency "took" before its official release.

  • 1983 – American crypto entrepreneurs David Chaum and Stefan Brands began working on the concept of "electronic" money and introduced the idea of electronic cash.

  • 1991 – Stuart Haber and W. Scott Stornetta developed a secure and secure digital ledger system, the blockchain. This laid the foundation for the further development of cryptocurrencies.

  • 1997 – Adam Beck proposed the concept of "HashCash" - a “proof-of-work” system used to limit e-mail spam and denial-of-service attacks. This concept later became a key component of Bitcoin's blockchain technology.

  • 2002 – Wei Dai created "b-money" - a system of anonymous electronic cash, which was one of the early concepts of cryptocurrency.

  • late 2008 – early 2009 – an anonymous person or group of people using the pseudonym Satoshi Nakamoto introduced the first digital currency, Bitcoin.

The process of digital currency development was difficult and quite long, but it was the early concepts of HashCash and b-money that paved the way for Bitcoin and other cryptocurrencies. Without them, it is quite possible that cryptocurrency might not be popular or would not exist at all.

What is cryptocurrency and how does it work?

A cryptocurrency is a type of digital currency that operates independently of a central bank or government. It uses cryptographic techniques to secure and verify transactions and control the creation of new coins.


The most famous cryptocurrency is Bitcoin (BTC), but thousands of other cryptocurrencies (Ethereum, Litecoin, TRON, USDT, etc.) are currently in circulation. If you compare digital currencies with fiat currencies, cryptocurrencies are not subject to inflation, government regulations or any restrictions.


In everyday life, digital currencies are used to pay for services / goods on the Internet. Many online stores (e.g. Etsy, Microsoft, Shopify) accept cryptocurrency as a form of payment. This makes it easier to buy from anywhere in the world, because there is no need to worry about exchange rates or commissions.


Investing is also a common way of using cryptocurrency. A good example of successful investing is Eric Fineman. At the age of 12, the boy invested $1,000 in Bitcoin, which his grandmother gave him, and at the age of 18, his investment exceeded $1 million, making him a millionaire.
