I know the Zen Wallet will only be available on the 23rd, so my question is

If i backup my Zclassic private keys after block 110.000, and afterwards sell my Zclassic, will i still be able to upload the backup keys to my Zen Wallet on the 23rd?

I dont want to use bittrex tomorrow, they will open Zclassic market when they want, wich makes it a very profitable information, i would rather use ccex.
