What is Cryptocurrency?
Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. Cryptocurrencies are decentralized and rely on a peer-to-peer network of computers to verify transactions and maintain the blockchain ledger.
The first and most well-known cryptocurrency is Bitcoin, which was created in 2009 by an unknown individual or group using the pseudonym Satoshi Nakamoto. Since then, thousands of other cryptocurrencies have been created, each with its unique features and use cases.
Cryptocurrencies are generally stored in digital wallets, which can be hardware or software-based. Transactions are validated through a consensus mechanism, such as proof-of-work or proof-of-stake, and recorded on the blockchain, which is a decentralized public ledger.
Cryptocurrencies are often touted for their potential to revolutionize the financial industry by providing a more secure and efficient way of transacting value. However, they also face challenges such as regulatory uncertainty, market volatility, and security concerns.

- Fork: A fork occurs when a blockchain splits into two separate chains. This can happen when the community disagrees on the direction of the cryptocurrency and decides to create a new chain.

A man named James Howells who accidentally threw away a hard drive containing 7,500 Bitcoins. Howells, a computer programmer from Wales, had mined the Bitcoins in 2009 and 2010 and stored them on his hard drive.
However, in 2013, he mistakenly threw away the hard drive, not realizing its value.
Realizing his mistake, Howells tried to find the hard drive in the local landfill, but was told that the chances of locating it were slim. The hard drive is now believed to be buried under thousands of tons of trash.
At the time, the 7,500 Bitcoins were worth around $4 million, but their value has since skyrocketed. In 2021, the same number of Bitcoins would have been worth over $300 million. The story of James Howells is often cited as a cautionary tale about the importance of safeguarding digital assets and being aware of their value.
