If we want crypto currency to be a currency we have to keep spending right? But at the same time it's something worth keeping too since I do the same with my fiat in bank for more than 2years without touching it. Is it possible to say that Bitcoin in every wallets for the past 2years without moving are considered lost due to death or lost recovery keys? It's pretty hard to believe that anyone won't come back for their Bitcoin after 2years with no activities on the wallet.
