How long does an average decryption take before the wallet can be made available to the owner? Is there like some kind of a waiting period like how people wait in line for their turn, or do you start working immediately the device gets to you, and also do you charge higher for encrypted devices??
Let me do the honor to give an answer to your question.
The average time to decrypt a wallet to when it will be accessible by the owner is not specific. It varies because it depends on how complex the issue is and more details the owner provides. Some wallets can be decrypt in days while some in weeks.
