Glad to help

Some Security consideration cases come to my mind:

1.  Withdraw from CP with Export Private Key in Electrum --> Spent the coins.
2.  Withdraw from CP with Export Private Key in Electrum --> Sweeping in Electrum --> Spent The coins.
3.  Sweeping directly from CP to an Wallet --> Spent the coins.

On an anonymity sight could someone explain the differences ( may in slightly easy words im not really a pro ) 

best regards
