How many wallets does 1 need for staking on 3rd party protocols or claiming airdrops?

People in this sub often suggest that dont use your main wallet for staking on 3rd party protocols or claim airdrops to avoid getting hacked and your crypto stolen. I have a no. of coins in my portfolio. If I want to stake them on their own chain or 3rd part protocols like stader then do I need a different wallet for every coin ?

Shoud I open accounts on multiple wallets or shoud I open different accounts on the same wallet that I already have ? What is the better practice in such a case ? What strategy do people with large portfolios use for safety of their funds & wallet accounts?
