Hello,
To understand the difference between the hot balance (such as CoinPayments balance), the user balances (including the admin balance) and other types of balances, please see the Glossary section of the documentation where all of these terms are explained.
It’s also worth checking the Cold storage section, because this is what you should be using to control the hot balance.
with regards
P.S. I have moved your question to a new thread since it is not related to your previous question about the faucet.
