Bitcoin is a worldwide payment system and a form of digital currency. Bitcoin is created electronically, unlike traditional currencies such as minted coins or printed bills. Unlike traditional currency, bitcoin is not controlled by a central bank and, by extension, no single authority can manipulate its value or destabilize its network. Users exchange bitcoins electronically via cryptographic addresses. This is done through third-party exchange sites.

1. WHAT IS BITCOIN?
Bitcoin is a worldwide payment system and a form of digital currency. Bitcoin is created electronically, unlike traditional currencies such as minted coins or printed

WHERE DOES BITCOIN COME FROM?
Mining is the process by which bitcoins are generated. Miners work together, using powerful computer processors, to solve a complex mathematical problem, which not
only uncovers new bitcoins, but also ensures the integrity and security of all bitcoin transactions.
WHO CREATED BITCOIN?
It is only natural that a cryptocurrency's origin story be shrouded in mystery. Satoshi Nakamoto has been associated with the invention of bitcoin since the first digital
paper on bitcoin appeared in 2008. Even now, almost 10 years later, we still have no idea who Satoshi Nakamoto was or whether bitcoin was the result of a group of
people working together.
So far, Hal Finney, Dorian S. Nakamoto, Craig Wright, and Nick Szabo, among others, have been considered possible candidates. As an homage to bitcoin’s purported
creator, a satoshi is the smallest divisible amount within one bitcoin, representing 0.00000001 bitcoin or one hundred millionth of a bitcoin.
WHAT ARE THE KEY FEATURES OF BITCOIN?
In part, bitcoin was created as an alternative to fractional reserve banking, so it's not surprising that it differs in some pretty significant ways from traditional currencies and
payment systems. Let's look at a few of them:
1. It’s decentralized
Users are in control of their bitcoins. Bitcoin is not controlled or manipulated by a central authority.
2. Personal information is not traceable to transactions
It protects users from identity theft, but it also led to bitcoin becoming a popular payment method for illicit black markets, such as the Silk Road, an online marketplace for illegal
weapons and drugs.
3. Minimal transaction fees
Currently, bitcoin payments have fairly low fees. Exchanges may offer a variety of services with varying fees depending on the type of transaction, but they are generally less
expensive than credit cards or PayPal.
4. Reduced risk for merchants
Bitcoin transactions are not reversible, do not contain any personal information, and are secure, so merchants are better protected from any losses that might occur from
fraudulent credit card use..
