Wrapped ETH on other chains post merge

1M Ago
I know that wETH on other chains such as polygon or avalance will ”work” just as they should post merge too, but I assume by having your ETH on other chains WILL result in losing the possible hard fork ”PoW ETH”? So would it be wise to have all your eth on the main chain when the merge happens, assuming the PoW coin will have some value above zero?
