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 Tether (USDT)?

    USDT is a stablecoin — a type of cryptocurrency that remains “tethered” to the price of the U.S. dollar. For every USDT, there should be an equivalent amount held safely by Tether Limited.

    Tether was created to serve as a safe haven in a volatile crypto market, enabling users to easily store funds and avoid intense price fluctuations. It was designed to work like a digital dollar, merging the stability of a nonvolatile asset with the technological capabilities of a cryptocurrency.

    Through the use of USDT, merchants, traders and individuals can send or receive money anywhere in the world, without using a middleman like a bank or incurring huge fees. Tether has also enabled crypto exchanges to provide more trading pairs, which has opened the gateway for more liquidity.

  • How does Tether work?

    At launch, Tether was built using the Omni Layer Protocol, which allows digital assets and other smart contracts to be created on top of the Bitcoin blockchain. All Tether tokens are backed on a one-to-one basis with the U.S. dollar, with collateral held in reserve. The circulating supply of USDT can be tracked by the protocol, and the ledger is also stored on the Bitcoin blockchain, with verified transactions viewable via Omni Explorer.

    When someone redeems USDT for dollars, the corresponding number of tokens are burned — and when someone purchases USDT, new tokens are minted.

    Tether has now expanded to allow USDT to work on other blockchains including TRON, Ethereum and EOSIO.

    As the tokens are backed by a government-issued fiat currency, the price of USDT should always remain stable. Through the use of USDT, traders can park their funds when markets are particularly volatile without having to cash out entirely. It's also a lot quicker and cheaper to exchange crypto to crypto, rather than crypto to fiat.
