skrill requires people to verify their accounts, if they deposit bitcoin in the skrill, then these bitcoins would be blocked until they pass the verification of account that is a great exhaustive process, they ask for a passport, proof of residence, location, you still have to go through the scanner (you have to install their application on your mobile phone to be able to pass on the face scanner that confirms that the photo of your passport has the same face as yours)... as I said, it is an exhausting process.
advcash ask people to verify their accounts and their support is very slow, it may take 13 days to respond to the support ticket, perfect money seems to be better option
