Beginner's Guide to the Crypto Space: Detailed Tutorial on Downloading Cryptocurrency Software and Purchasing Currency
Don't worry, there are no barriers to purchasing cryptocurrency. You can buy BTC for 100 yuan, or even 50 yuan. If it's not profitable, why are so many people eager to enter the cryptocurrency space? Those who make money will never tell you how much they earned from Bitcoin. Follow my article step by step to learn how to purchase Bitcoin. This article provides a detailed tutorial for beginners on how to purchase cryptocurrency for the first time, including registering on the OKX exchange, downloading the OKX app, buying and selling USDT, and purchasing and selling mainstream cryptocurrencies like Bitcoin and Ethereum.
First, it is important to understand that a stable, secure, and efficient exchange is the prerequisite for arbitraging in the crypto space. All our virtual currency transactions need to rely on a reliable exchange. The exchange we will use today is the OKX platform, which, in terms of experience and reliability, is undoubtedly the first choice for users in the country.
Here, I recommend using the OKX exchange, which was established in 2013 and is the second largest virtual currency exchange in the world.
Its registration and user numbers consistently rank among the top in many exchanges. It not only supports KYC identity verification for users in mainland China but also makes operations like depositing, buying and selling virtual currencies, and withdrawing funds easy to understand, making it very friendly for locals.
Previously, many exchanges in the country cleared out KYC users, but only OKX did not. In terms of security, OKX is also the highest in the country.
Next is the trading experience and depth. Personally, I have been using it smoothly since 2017, and I recommend new users choose OKX. If you haven't registered on OKX yet, you can click the invitation link below and open it using your phone's built-in browser or Google Chrome. Using my OKX invitation link will permanently grant you a 20% fee discount, which is effective for both contracts and spot trading and is permanently valid.
Registering an OKX Exchange Account
We click the link and choose a browser to open it. Once inside, we will see a registration page. First, select your country and region, and choose "Mainland." Click to create an account, agree to OKX's terms of service, and click [Next].
Confirm your residence address and click [Confirm].
Here, we enter an email address; Google Mail, NetEase Mail, and Outlook Mail are all acceptable. There is an optional invitation code below; if you registered through the link, it will be automatically filled in for you, then click [Register].
He will send a 6-digit verification code to your email; we will check and fill it in here.
He will ask you to bind a phone number; we will bind it ourselves. Directly bind our mainland phone number, which is +86. Then enter the phone number and click [Verify Now].
He will send a verification code to your phone; we will enter the SMS verification code again and click [Next]. Next, you will be prompted to set a password; set a password, and our OKX account will be registered.
Download the OKX App and Complete Identity Verification
Next, we need to download the OKX app. First, click the "top left corner" of the invitation link to open the OKX official website, then click the download icon in the top right corner, which is a downward arrow. Android users can directly scan the QR code to download; if there are any interception issues when scanning with the phone's built-in browser, you can use Firefox.
We can also directly click "More Clients."
On this page, click to download the OKX app, and you will see a download QR code; Android users can download it through this QR code.
Apple users cannot download the OKX app using a domestic ID; we can directly search for "Apple ID" on Taobao to purchase a permanent Korean or Singapore ID for easier app updates in the future.
After purchasing and logging in successfully, we directly search for "OKX." After searching, do not look at the first one; directly look at the second one, as the second one is the official OKX. Make sure to recognize the icon and do not download the wrong one, then install it.
After registering and downloading, we first open the OKX app. Click the nine small dots in the top left corner, then click your profile picture. On the personal information page, click "Identity Verification." After registering and downloading, identity verification is required; this step is necessary for everyone, or you will face significant restrictions when buying coins. After real-name verification, not only can we increase our fiat trading limits, but also the withdrawal limits for Bitcoin, and it will make our asset accounts more secure.
Then click to verify; it will prompt us to provide the following information: identification and facial recognition, as well as residence address. We click to verify now. Choose "Mainland" for the residence country, select "ID card" for the document type, and click [Next]. He will require us to upload a photo of the ID card, and then facial recognition will be needed; everyone can verify it themselves.
After completing identity verification, we can directly purchase USDT. Click [C2C Buy Coins] on the OKX homepage.
You can see there are three options at the top: C2C Buy Coins, Quick Trade, and Bulk Trade. "Quick Buy Coins," as the name suggests, is more convenient, as the platform will automatically match us with a merchant. "C2C Buy Coins" has many filtering requirements, allowing us to filter merchants according to our needs. The method we demonstrate today can be used whether you are buying USDT in large or small amounts.
We choose "C2C Buy Coins" and want to purchase USDT, which is Tether.
Filter the amount, enter how much USDT you want to buy; today I will use 20 yuan for demonstration, and click [Confirm]. This will filter out all merchants that meet your needs.
For payment methods, there are bank cards, Alipay, and WeChat; all three payment methods are acceptable. Today, I will demonstrate using Alipay, select "Alipay," and click [Confirm].
Here you can see many merchants are engaged in this business; we should try to filter for a merchant with a high transaction volume and high transaction rate. We can also click on the merchant's name to check their homepage to see if their registration time is long enough.
You can see that the merchant "Dadong Baizishanghang" was registered on December 8, 2023, and their deposit is very complete, including video verification, identity verification, phone, and email; these procedures are very complete, which is enough to prove they are a relatively reliable merchant. We can also see their transaction numbers and transaction rates are very good. We can proceed with the transaction with this merchant, click back, and directly click [Buy].
Re-enter the amount you want to purchase; the system will automatically calculate that paying 20 yuan will receive 2.75 USDT. The payment method is Alipay for immediate payment, then click [0 Fee Purchase USDT] below.
A C2C trading safety prompt will pop up; let's take a look. "Do not use third-party platforms to chat with the other party; please always communicate through OKX. If you have already paid, do not cancel the order; if the other party requests this, be sure to file a complaint." Click [I understand].
We can also click [Chat] to see if the merchant has any requirements.
We return and click [Get Payment Details] below, and the other party's Alipay account and QR code will appear. We directly save their QR code and go to our Alipay to transfer the money. After transferring the money, click [I have paid].
Confirm payment; I have transferred 20 yuan to the other party via Alipay, click [Confirm].
Wait for the seller to verify receipt of the money, and they will release the coins to us. Our transaction is complete; the seller has confirmed receipt, the transaction is complete, and the assets have been credited to my fund account. We can directly click "View Assets."
You can also click the asset icon in the bottom right corner, find the fund account at the top, and here you can see the USDT you purchased.
If we need to trade, we must transfer from the fund account to the trading account to proceed with the transaction. We directly click "Assets," then click [Transfer].
From the fund account to the trading account, select USDT as the asset, choose the maximum amount, and click [Confirm]; this way, we have successfully transferred.
We can go back to check, and USDT has been transferred from the fund account to the trading account; the entire process of purchasing USDT is now complete. Next, you can use USDT to buy any cryptocurrency you want.
Selling USDT for RMB
Next, we will continue to demonstrate how to sell USDT. There are several important points that everyone must pay close attention to, as they will play a crucial role in your account security.
After trading, we first need to transfer USDT from the trading account back to our fund account before we can withdraw funds. We click [Transfer] here.
From the trading account to the fund account, the asset is USDT, click "Max" for the amount, and click [Confirm]; the transfer is successful.
Going back, we can see that USDT has been transferred to the fund account.
After the transfer, return to the homepage and still choose [C2C Buy Coins].
Click [Sell]. We still choose C2C trading for selling, as the security of C2C trading is better than quick trading. Here we can use a few small tricks to help ourselves filter merchants; the currency is still USDT, and we can enter the amount we want to sell, then click [Confirm].
Filter payment methods; I will still demonstrate using Alipay.
After filtering, many merchants will appear; we should not randomly select a merchant for the transaction. The next three points are very important; you must pay attention to them, as selecting a merchant is a crucial task.
- We should choose a merchant with a high transaction volume.
- We should choose a merchant with a high transaction rate.
- We should choose a merchant with a long registration time.
On this page, we can see that this merchant has a decent transaction volume and transaction rate; we can click into their homepage to check if their third item meets the criteria. We directly click [Sell].
Re-enter the amount of USDT we want to sell; you can see that selling 2.75 USDT will receive 19 yuan, then directly click [0 Fee Sell USDT] below.
Confirm the order information and click [Sell].
Enter the security verification and click [Confirm].
On this page, we can see the quantity of USDT to sell, the unit price, the total amount we will receive, and the payment method, which is Alipay. We directly click [Chat] and wait for the buyer to confirm payment. The buyer has now paid; we directly click to confirm receipt.
Check your receiving account or ask the seller if the payer's name is this person. Click "Yes," then click [Confirm Release], and our transaction is complete; the buyer has paid, and we can confirm receipt.
