In the last lesson, we successfully built and strengthened our 'wealth vault'—a highly secure exchange account. Now, the vault door is open for you; it's time to deposit our first piece of shining 'digital gold'!
I know that using real money to purchase virtual cryptocurrencies for the first time may make you feel a bit anxious: 'Where will my money go?', 'Is this process safe?', 'What if I make a mistake in the operation?'
Please calm your nerves. In today's lesson, I will transform into your exclusive navigator, guiding you step by step from the real world to the crypto world for the 'last mile.' You will find that the entire process is much simpler, quicker, and safer than you imagined.
Are you ready to embrace the joy and sense of accomplishment of 'successful purchase'? Let's get started immediately!
1. Why buy USDT first? Review the concept of 'crypto dollars' 💵
Before we start operating, let's quickly review a core concept: Why don't we buy Bitcoin directly, but first buy USDT?
As discussed in Lesson 2, USDT is a stablecoin that is pegged to the US dollar at a 1:1 ratio, hence it is referred to as 'crypto dollars.'
Imagine you are going to a large multinational amusement park (crypto world), where there are various fun projects (various cryptocurrencies). The most convenient way is to first exchange your local currency for a universally accepted 'token' at the entrance of the amusement park.
USDT is the most universal 'token'. Once you have it, you can easily 'play' any project you want.
2. Best path for beginners: Detailed explanation of the entire C2C trading process 🤝
C2C (Customer-to-Customer) trading is currently the most suitable and mainstream method for beginners to deposit funds.
Core principle: You are not buying coins directly from the exchange, but rather purchasing from individual merchants on the platform like you and me. The role of the exchange is to provide a guarantee platform to ensure 'payment upon delivery,' protecting the safety of both buyers and sellers.
Next, please open the Binance APP you have already set up, and we will start the practical exercise.
3. Ultimate Practical Exercise: Complete your first purchase in four steps ✅
Step 1: Find the C2C trading entrance
Open the Binance APP, and in the most prominent position on the homepage, click 'Add Funds' or 'Recharge' to find the 'C2C Trading' button. Click to enter.

Step 2: Carefully select 'Gold Medal Sellers'
After entering the C2C page, you will see a list of merchants. Do not choose randomly! Just like selecting a crown seller on Taobao, we also need to choose the most reliable merchants.
At the top, make sure you select the 'Buy' option, and the currency is 'USDT.'
Click 'Filter', enter the amount you want to purchase (for example: 500 CNY), and choose your preferred payment method (for example: Alipay or bank card).
Here comes the key point! Check the merchant data: Prefer merchants with a high 'total order number' (over thousands) and a high 'completion rate' (over 98%). These data represent their credibility and efficiency.

Step 3: Place the order and make precise payments
After selecting a merchant, click 'Buy', enter the amount you want to purchase, and then click 'Place Order'.
The platform will generate an order, and the page will display the merchant's payment information (name, bank account, or payment code).
[Key Step]: Open your own banking APP or Alipay, and strictly follow the recipient's name and account number displayed on the order page to complete the transfer.
[Highest Level Warning! Must Comply!] In the 'Remarks' or 'Memo' section of the transfer, absolutely, absolutely, absolutely do not write any sensitive words related to cryptocurrency such as 'Bitcoin,' 'USDT,' 'Binance,' 'Crypto,' etc.! This is to protect your bank account from being controlled. If the merchant has no special requirements, keep the remarks blank!

Step 4: Click 'I have paid' and wait for receipt
After completing the transfer, be sure to return to the Binance APP's order page and click that yellow, most important button—'I have paid, notify the seller.'
After clicking, the system will start a countdown, and the merchant will verify whether their account has received the payment. Once they confirm receipt, the exchange system will automatically transfer the USDT that has been pre-locked on the platform to your account.
When you see the page prompt 'Order Completed' and receive the notification that the assets have arrived—

🎉 Congratulations! You have officially completed your first investment and successfully entered the crypto world!
📖 Summary:
Today, we injected our first funds into our 'wealth vault' through safe and reliable C2C trading, completing the most critical leap from 0 to 1!
✅ Task:
Action is the best teacher! I strongly recommend that you take advantage of the situation and use a small amount of funds (for example, 100 or 200 yuan) to fully experience the C2C purchasing process. The experience and confidence gained from hands-on operation are more valuable than reading ten articles!
