I hold some in bitpanda.com and some in blockchain.info

During this whole fork situation - where should I keep my bitcoins? Should I download the bitcoin core wallet to my computer and move the coins there?

Should I just leave them in their online wallets?

If I move them to a local computer wallet, what do I need to do when bitcoin forks? Do I need to do something to get the same amount of coins in the new chain? (Download a core wallet for the new one so I have bitcoins in both the original and the forked?) (if so how??)


Thankyou all - I don't really care about which chain is the successor etc I just care about being on THE chain and not being left with coins in the wrong place


Thoughts appreciated
Thankyou
