How to buy cryptocurrency and store it safely?
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.

What is cryptocurrency?
A cryptocurrency is like a traditional currency in many ways, but it instead uses a unique type of online database, called a blockchain, to store unchangeable ownership records. This ledger's integrity is protected using advanced cryptography techniques, which give cryptocurrency its name. While Bitcoin, or BTC, is the leading cryptocurrency today, there are thousands more traded freely on exchanges like OKX.

Since cryptocurrencies require no central authorities or banks, these assets are held in addresses accessible with private keys that must be kept secure to protect funds. This also means anyone with the private key will have actual ownership of the associated coins, allowing them to move or transfer them freely. When buying cryptocurrency, it is recommended that users either keep their private keys secure or use a secure exchange like OKX, which uses industry-leading security infrastructure to keep user funds safe.
