What is bitcoin 

Bitcoin is a digital currency that was created in 2009 by an unknown person using the name Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by trading it. Bitcoin is a decentralized currency, which means that it is not controlled by any government or financial institution. Instead, it uses a technology called blockchain to manage transactions and ensure the security of the network. 

The blockchain is a public ledger of all transactions that have ever been made on the Bitcoin network. It is maintained by a network of computers around the world, and each new transaction is verified by a network participant before it is added to the blockchain. This makes it nearly impossible to manipulate the system or double-spend coins. 

One of the main advantages of Bitcoin is that it allows for fast, low-cost transactions across borders and without the need for a middleman. This has made it popular for remittances and cross-border payments. However, Bitcoin's price can be highly volatile, which means that it is not a stable store of value like traditional currencies. It is also subject to regulatory scrutiny and has been associated with illegal activities such as money laundering and online black markets. 

Overall, Bitcoin is a revolutionary technology that has the potential to transform the way we do business and exchange value. It has already paved the way for other cryptocurrencies and blockchain-based applications, and its impact on the global economy is likely to continue growing in the years to come.
