no. you don't have to do anything.
(if you don't mine)
but it is always advisable to have your coins in a certain wallet

what wallet do you recommend ? i currently use EXODUS

i depends on the usage.

Cold wallet : paper wallet, ledger nano, etc.
Hot wallet : myetherwallet , metamask, parity, (, mist) ...

i don't know much about exodus wallet, but maybe you feel rationally comfortable with it.
It is useful to manage several cryptocurrencies in one wallet.
just be aware if you just want to hold your ether you should prefer a cold wallet.
if you want to make transactions just try some Wallets and find out which one works for you the best.
But be aware that there are scammers, phishing attacks and other things going around the wild west. (e.g. myetherwallet)
