If you sell anything for crypto, these are the mistakes that cost people money:
2. Address poisoning
Scammers send you a tiny or zero-value transfer from an address that looks like one you use (same first and last characters). Later you copy the "recent" address from your history and pay the scammer.
Fix: never copy addresses from transaction history. Use a saved address book and check the full address, not only the ends.
3. Wrong network
USDT exists on several chains (TRC20, ERC20, BEP20...). Always state the network next to the address. Funds sent on the wrong network are often unrecoverable.
4. Fake "payment sent" screenshots
Only trust the blockchain explorer, never a screenshot. Paste the TXID yourself and check recipient, amount and confirmations.
5. Reusing one address for everything
Makes your whole history public to anyone you've traded with. HD wallets generate a fresh address per payment for free.
6. Keeping everything in a hot wallet
Move profits you don't need daily to a hardware or cold wallet.
7. Approval scams (EVM chains)
Signing a "token approval" on a random site gives it permission to move your tokens. Review and revoke old approvals regularly with a token approval checker.
