There are different statuses given to deposit requests so as to recognize at which stage of the process they are:

APPROVED: The deposit has been completed and the funds should be visible in your wallet.

WAITING CONFIRMATION: The funds are being processed by their respective network. Usually, the funds need 1-3 hours to receive the necessary amount of confirmations, depending on the network traffic.

WAITING APPROVAL: The deposit was not sent to the processing network yet.

REJECTED: The deposit has been rejected. You should have a note in the comment box next to your payment with further details. 

CANCELED: The deposit has been canceled. A deposit gets automatically canceled if the process was not completed within 48 hours. Customers can also cancel a deposit request if needed.
