What is BTC

Bitcoin is the world's first decentralized cryptocurrency built on blockchain technology. Bitcoin was launched in January 2009 by a pseudonymous person or organization, Satoshi Nakamoto. BTC is the name and ticker of the Bitcoin blockchain network.

The Bitcoin network allows users to transact value directly without going through intermediaries like banks or other financial institutions. Bitcoin transactions are validated by nodes called miners. To validate Bitcoin transactions, miners generate a cryptographic proof of work by solving the mathematical problem set by the Bitcoin protocol.

Bitcoin has a hard-capped supply of 21 million units, making it a deflationary asset. Out of 21 million Bitcoins, over 18.9 million are already in circulation. Miner nodes are rewarded with Bitcoins to verify Bitcoin transactions which are how new Bitcoins enter circulation. Additionally, the Bitcoin miner rewards are decreased by half every four years, further reducing the rate of Bitcoin inflation.

Bitcoin's fixed supply, decentralization, and security have made it the most popular cryptocurrency to date. In fact, Bitcoin remains the world's largest cryptocurrency by market capitalization even a decade after its launch.

Cryptocurrency is a new class of digital assets popularized by Bitcoin (BTC). While cryptocurrencies or digital/virtual currencies work much like their traditional fiat counterparts, the biggest difference between the two is the lack of centralized infrastructure and banks.

Where fiat currencies are issued by and kept in banks, digital currencies are issued via distributed mechanisms that follow strict consensus protocols. This translates into cryptocurrencies being stored on blockchains which are largely immutable, much more transparent and globally accessible.

Given their utility and growing list of use cases, cryptocurrencies are gaining popularity and one way to buy cryptocurrency is to use a reliable crypto exchange like OKX. On OKX, users can sign up, verify their identities and start buying Bitcoin and other cryptocurrencies instantly using credit cards, debit cards, bank transfers and other supported payment methods.

Typically, when you buy cryptocurrency, you have to store it in a dedicated wallet, but the security of your digital assets depends on how safely your private key is kept. Every cryptocurrency wallet has a private key which allows complete access to the stored digital assets. If you lose your private key, you effectively lose your funds.

Using an exchange like OKX also facilitates users because their newly purchased or traded digital assets are kept securely on the platform and are credited into users' accounts, available to be sold or transferred as required.

Ultimately, users should always buy cryptocurrency from a reliable exchange, and if they withdraw their digital assets to a personal wallet, they should keep their private keys safe and backed up to ensure the security of their funds.
