Should I upgrade this wallet every time if I'm just holding some coins?
No reason to upgrade if you don't plan too stake or move coins. Just upgrade the next time you need too move coins.
wrong. It is a mandatory upgrade

it's a mandatory update but as long as you have your private key(s) your are fine. If you don't plan to send coins and you're not staking them you don't have to update anything. Every wallet works this way.
Anyway, for all the others:
Update your wallet guys!Sooner rather than later he will be sending coins anyways so why not do it now lol. Besides it only takes 2 minutes, you only download the ZIP file. Replace the old wallet with the new one and you are good ( if you have your wallet.dat in %appdata% it will sync automatically )
His question was whether he should update if he plans to hold only, the answer is no. Not everyone is able to stay on date with all the update we have.
You are making it harder than it is lol.
Devs: This is a mandatory upgrade.
JJack@: ok
JJack@: Thanks, it took 2 minutes and my coins are now safer!
