Great article. I prefer the Greymass wallet and in early days they had released a cold storage feature built in to sign transactions offline (believe it would allow an air-gap computer to function like a hardware wallet).

One thing you might consider to look into is Chintai leasing service for idle tokens. There are 7 day to 28 day leases at the moment. The thing is you have to use Scatter currently versus other wallets, if I recall correctly. I've been considering going through with it because the APRs reached crazy levels in the recent week.
