Before you move money
A short checklist, at the level of concepts. It is not a guide to opening an account at any particular venue.
The right network
USDT on TRC-20 is not USDT on ERC-20. Sending on the wrong network usually means it is gone.
The right address
Copy, paste, then compare the first and last few characters. Malware can swap addresses in the clipboard.
A small test first
Send a small amount, wait for it to arrive, then send the rest.
Read the term and the withdrawal time
A fixed term locks funds until maturity; staking often has a wait of several days.
Save the promo conditions
Take a screenshot of the rate, cap and promo end date when you deposit: conditions can change later.
Put it in your book
Record the deposit to be told when the rate drops, a promo ends or the venue has an incident.
