- By selecting MAIN you'll see and manage your BCH through the old HD path of Bitcoin (0'). This is the most simple way to manage your coins, as your BCH are already there. But it could also be more simple, so more tempting, for possible future malicious attacks.
- By selecting SPLIT you'll see and manage your BCH through the new HD path of Bitcoin Cash (145'). It will require you to make a transaction from the MAIN account to the SPLIT account (you'll have to spend some fees). But it could also be safer as you'll have new keys for this particular account.
It is up to you: you can then choose to transfer from one path to another at your convenience - nothing is mandatory. This choice is done as an additional protection layer against scammers that could lure you into transacting on the wrong chain.
