Many people’s first step into the circle is buying USDT, but many end up spending hundreds or even thousands more on their first trade before they even start investing. These losses can actually be completely avoided. Today, let's discuss the 3 key points that must be understood before purchasing USDT.
1. Beware of exchange rate traps to avoid passive premium
As a stablecoin pegged to the US dollar, 1 USDT should theoretically equal 1 dollar. However, in practice, there is often implicit premium when purchasing USDT with RMB. Common situations include:
• When the real-time exchange rate is 7.2, seller quotes are 7.5-7.8
• Purchasing 1000 USDT may result in overpayment of 300-600 RMB
• Hidden unreasonable price differences in OTC trading
Practical suggestions:
Use authoritative financial apps to check real-time exchange rates
Calculate the actual cost of one USDT (total price ÷ quantity)
Prioritize compliant trading platforms with transparent quotes
2. Understand blockchain networks to prevent asset loss
USDT exists on multiple chain versions; transferring on the wrong chain will lead to permanent loss:
Main version comparison:
│ Chain Type │ Transaction Fee │ Arrival Speed │ Applicable Scenarios │
│─────────│───────│──────────│─────────────│
│ TRC20 │ Lowest │ Fastest │ Preferred for daily transfers │
│ ERC20 │ Higher │ Slower │ Institutional-level trading │
│ BEP20 │ Medium │ Fast │ Circulation within Binance ecosystem │
Hedging strategies:
Double-check chain type before transfer
For first-time trades, conduct a small test transaction
New users are advised to use the TRC20 channel
3. Master the essentials of asset storage to ensure fund security
Common storage misconceptions:
× Long-term retention on trading platforms
× Electronic storage of mnemonic phrases
× Using wallets of unknown origin
Correct practices:
Choose storage methods based on holding periods:
Short-term: Exchange accounts
Medium to long-term: Decentralized wallets
Adopt a "cold and hot separation" strategy:
Hot wallets store small amounts of liquid funds
Cold wallets safeguard large assets
Mnemonic phrases must:
Be handwritten on fireproof and moisture-proof media
Absolutely avoid network transmission
Distributed physical storage in multiple locations
Important supplement: Safety first principle
• Refuse the temptation of "ultra-low prices"
• Verify platform compliance qualifications
• For first trades, choose daytime working hours
• Retain complete transaction evidence
Final summary
Price comparison: Calculate costs against real-time exchange rates
Verify chain: Confirm network consistency of sending and receiving addresses
Custody: Choose appropriate storage solutions based on needs
Remember: Standardization is half the success. Spending 10 minutes on these preparations can avoid 90% of beginner mistakes in the future. The investment journey is long, and safety is always the first lesson.
