To make sure that your XMR and keys can't be compromised in any way you should do the following:

- Create a new wallet especially for the fork and move your XMR to this wallet.
- ‎after the snapshot move your XMR back to the original wallet
- ‎You can then use your newly created wallet, that holds no XMR anymore after the snapshot, to claim your MoneroV

You should do it that way with every fork.
