Can somebody give me A Very Good option about whats gonna happen and why with A Good and easy explanation

And what to do best with A big stack of btc?

??
Let me know thnx
If you own coins in a wallet to which you own the private keys then after any chain split you will own coins on both chains, you can keep both or sell both, either way buying now ( and taking coins off exchange) gives you options, buying after a fork, you have to pick which chain and hope you pick the right one, or buy on both chains.
I keep all of my btc on a ledger wallet and only +-20 on kraken it Good like this or to put nothing on kraken ?
