Select your ClearLoop™ account connected to BIT exchange
Select the asset you would like to deposit and click [Lock](USDT is recommended).
Locking assets from other Copper account to the connected ClearLoop™ account.
Your BIT account adds assets automatically on Assets Page. Deposits can be viewed by [Assets History].
For sub-account deposits, assets are deposited into main account automatically, then manually transferred from main account, which more details refer to Sub-account Setup.
