wallet minig

Hello, please help me
I use the wallet address of a local exchange. Is this wallet address valid or should I use the new Candidate wallet address Quinomi or Blockpin wallet to deposit the profit of my mining machine? Please help. I am afraid of losing my assets.
My current wallet address is this or is it a valid address or not?
