🔍 Summary Analysis
Perspective Suggestion
Pursuing Compliance/Transparency Choose USDC, suitable for DeFi, ecosystem points, institutional cooperation
Pursuing Liquidity/Transfer Speed (such as exchange transfers) Choose USDT, especially Tron-USDT (low fees, fast speed)
High Cross-chain Demand USDT supports more chains; but USDC is also rapidly expanding on multiple chains (like Base and Arbitrum)
🧠 Practical Suggestions
When operating fast in and out on exchanges → Using USDT is more convenient
If participating in DeFi or NFT, Layer2 ecosystems (like Arbitrum, Base) → USDC is safer and more suitable
If it is for institutional or corporate reserve funds → Most would prefer USDC due to compliance and reserve audit transparency
