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.
Bitcoin will not die in the wallet even if the wallet cannot be opened again due to loss of the private key. And the movement will remain the same as you see the Bitcoin in the wallet that you can still open now. For cryptocurrencies that you want to use as currency, of course you have to see if the cryptocurrencies have started to be accepted in your country and also by any sellers in your area. Because you also can't spend it alone unless you enter the market like other traders.
