Comprehensive Bitcoin Investment Guide for Users After 2025
The Most Detailed Bitcoin Investment Guide for Users After 2025!
Bitcoin has recently surged to a new all-time high, reaching approximately $110,000. Short-term price gains were driven by positive news around Trump's re-election as U.S. President. The 2024 U.S. election has been termed the "Cryptocurrency Election," with Trump earning the nickname "Cryptocurrency President" due to his consistent support for the industry this year, including attending the 2024 Bitcoin Conference and proposing Bitcoin as a U.S. strategic reserve asset.
Over the past year, Bitcoin's performance has shifted perspectives among traditional investors and institutions, prompting increased cryptocurrency allocations. The approval of Bitcoin ETFs earlier this year solidified this trend. Simply put, if you envision Bitcoin's value decades ahead and recognize the need for early positioning, your life trajectory could transform accordingly.
Many users now seek guidance on Bitcoin investment. This comprehensive guide covers everything from exchange registration and identity verification to purchasing Bitcoin—all in one place! For Bitcoin investing, this guide is all you need.

1. Exchange Registration
Registering on OKX (formerly known as 欧易)
An exchange serves as a centralized trading platform for buying Bitcoin. Among Chinese users, OKX and Binance are the most popular, ranking first and third globally. Registration and verification are straightforward, requiring only a phone and ID card, typically taking under 10 minutes.
OKX boasts the largest Chinese user base, featuring an intuitive interface ideal for beginners. The registration process is detailed below:
Access OKX official site — VPN required or OKX alternative domain
- Complete your registration details, then download and install the app from the App Store or Google Play (refer to Figure 1).
- Open the OKX app and tap "Register/Login" at the center of the screen (Figure 2).
- Select "Register Now" (Figure 3).
- Choose China as your country/region, then tap "Next" (Figure 4).
- Enter your email and input invitation code 71309601 (Figure 5). This provides a lifelong 20% discount on OKX trading fees, supporting this tutorial—thank you 🙏.
- Input your phone number and tap "Verify Now" (Figure 6).
- Set your password (Figure 7).
- Create a passkey for enhanced account security (Figure 8).
- On the app's main interface, tap "Go to Verify" to initiate KYC verification (Figure 9).
- Tap "Verify Now" (Figure 10).
- Select China as your residence country, ID card as the document type, then tap "Next" (Figure 11).
- Prepare your ID and tap "Start Verification" (Figure 12).
- Upload the front side of your ID card (Figure 13).
Follow the prompts to complete KYC smoothly.
Congratulations! You've successfully registered on your first cryptocurrency exchange 🎉, likely in under 10 minutes.
Registering on Binance
Next, register on Binance, the world's largest exchange.
Binance registration process:
Open Binance official backup domain: Binance Registration
- Fill in your information, then download the Binance app from the Apple App Store or Google Play (avoid the US App Store due to potential version limitations).
- Open the Binance app and tap "Register/Login" (Figure 2).
- Tap "Create Binance Account" at the bottom left (Figure 3).
- Enter your email or phone number (domestic or international options are acceptable, Figure 4).
- Input invitation code 855276264 to support this tutorial—thank you 🙏 (Figure 5).
- Registration completes here, but KYC verification is required before buying Bitcoin. A Chinese ID card suffices; no overseas documents are needed.
- Tap "Identity Verification" (Figure 6).
- Tap "Start Now" (Figure 7).
- Confirm China as your residence and ID-issuing country, select ID card as the document type, then tap "Continue" (Figure 8).
- Upload or photograph the front and back of your ID card (Figures 9 and 10).
- Complete simple facial verification (Figure 11).
- Confirm your basic details (name and birthdate, Figure 12).
- Your KYC status enters "Under Review," typically resolving within a day.
- While awaiting KYC, enhance account security with passkeys, authenticator apps, email verification, and strong passwords (Figure 14).
2. Buying Bitcoin on Exchanges
After KYC completion, the first step is purchasing USDT, not Bitcoin directly.
A brief introduction to USDT: It's a stablecoin pegged 1:1 to the US dollar, acting as the universal currency in crypto. To buy any cryptocurrency, you must first acquire USDT, then exchange it for other coins.
Why not buy Bitcoin directly with RMB, USD, or EUR? Many countries classify cryptocurrencies as high-risk speculative assets, lacking legal recognition. High demand led to stablecoins like USDT for seamless trading. Major stablecoins include USDT and USDC, with USDT being the most common on Binance and OKX.
Purchasing USDT on Binance or OKX occurs via C2C (customer-to-customer) trading with platform merchants, using Alipay, WeChat Pay, or bank transfers. Safety is generally assured: orders place USDT in exchange escrow until payment confirmation. If sellers withhold USDT after payment, file a complaint with the exchange.
Binance USDT Purchase and Bitcoin Buy Process:
- Open the Binance app, search "C2C Buy Crypto" at the top, and tap to enter the buy page.
- USDT appears as the default purchase currency.
- Enter the RMB amount you wish to spend on USDT.
- Select your payment method: Alipay, WeChat Pay, or bank card (Alipay recommended).
- Filter for high-reputation "Shielded" merchants with high completion rates, then tap "Buy."
- Reconfirm the amount and place your order.
- The order generates; review payment details.
- Follow seller instructions (payment account, QR code, chat messages) to transfer funds.
- After payment, send a screenshot in chat; the seller releases USDT.
- Check your funds page for the USDT balance, usually in the "Funding Account."
- Transfer USDT from "Funding Account" to "Trading Account."
- Return to the app home, search the BTC/USDT trading pair, and select "Spot" (not contract).
- View the BTC candlestick chart and tap "Buy."
- On the buy page, see available USDT and options ("Limit" or "Market" order).
- Limit orders set a specific price (e.g., 59,000 USDT per BTC), executing when reached. Market orders buy immediately at current prices.
- Enter the USDT amount to spend (e.g., 10 USDT) for fractional BTC.
- Confirm the purchase—congratulations, you now own your first Bitcoin! 🎉
The OKX purchase process is highly similar and not repeated here.
Bitcoin Investment Tips
Adopt a long-term mindset; consider dollar-cost averaging (DCA) with fixed monthly investments, such as 1000 RMB. Bitcoin's halving cycles create strong periodicity—long bear markets and short bull runs—so savvy investors may use Bitcoin options for additional gains during bulls.
Reiterating a key point:
Newcomers should stick to spot buying Bitcoin. Avoid complex products like leverage, futures contracts, and "earn crypto" offerings to prevent significant losses.
