My advice to cold storage HoDLers: refresh your neurons with your passphrase/PIN/whatever you use to protect your wallet, by viewing your cold storage balance every 6 months or so. You never know when your memory may fail and you end up not being able to remember the key(s) to your precious coins.
Mine is on an offline / airgapped tablet that has never connected to anything except to have Electrum installed on it. May upgrade to a "real" hardware wallet like a Trezor one day.
