What does that mean for you?
A service account can have its own charges or rules about crediting a balance. Those terms are separate from the Bitcoin network fee. Read what the account provider actually charges.
Moving received bitcoin later is a new transaction and can involve a fee of its own. Receiving and later spending are different events.
Can you picture an example?
Imagine a friend sends to an address you provide. The network does not ask you to send recovery words or pay a stranger before the address can receive that payment. An unexpected demand deserves a pause.
What should you remember?
An entry marked waiting is not the same as a confirmed payment. Ask what status you are seeing and whether a service account is involved. Do not confuse a demand in a message with a rule of Bitcoin.
