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.
2 years is very short because the holder holds longer than that; it should be like 6 years or more because if there is still no movement from those years, for sure it was a lost bitcoin or the owner died. That was very long if there was no activity on that wallet. Also, if bitcoin was already lost, it will be gone forever unless you find the private key for an unknown reason and can open it again. Not sure if those people who hold morethan 6 years is that what are their target selling point.
