For example, Binance is the world's top trading platform, supporting a wide range of cryptocurrency transactions; Sesame Open Door (gate.io) has a long history and is famous for its high security and convenient trading processes; OKX is suitable for beginners, with a user-friendly interface and simple operation processes. You must register and download the application through official channels or visit the official website to avoid clicking unreliable links and prevent phishing attacks.
2. Register and complete identity verification : After completing the registration process, you must pass identity verification (KYC) to ensure account security and prevent illegal activities such as money laundering and fraud. Usually, you need to upload pictures of your personal valid ID, such as your ID card or driver's license. In some cases, you may also need to take a photo with your ID card and further verify your identity.
3. Recharge fiat currency : Since domestic money cannot be directly traded with cryptocurrencies, you generally need to first exchange your own money for USDT. USDT is a one-to-one cryptocurrency with the US dollar and is issued by Tether, a company in the United States. The recharge methods supported by different platforms are different. Common ones include bank transfer, Alipay, WeChat payment, etc., just choose the method that suits you.
4. Buy Bitcoin : After the account has sufficient fiat currency balance, find the "Buy" or "Buy" button in the trading platform, select the amount of Bitcoin you want to buy, and complete the transaction as directed. The operating interface of most platforms is intuitive and easy to understand, and novices can easily get started.
5. Store Bitcoin : After purchasing, consider how to store Bitcoin safely. There are mainly two types of hot storage and cold storage. Hot storage is connected to the Internet, which is convenient for daily transactions, but has relatively low security; cold storage is safer to store Bitcoin offline, but it is not as convenient as hot storage. Long-term holders recommend using cold storage to store most of the assets, leaving a portion for hot storage in case of emergency needs.
