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.
We cannot decide too quickly that a bitcoin that has not been active for 2 years in a wallet is a bitcoin that is lost or ownership is no longer able to access the wallet, because sometimes many investors make long-term investments and they after buying the first bitcoin then leave the bitcoin without looking back until the time comes at a predetermined time to avoid panicking if the bitcoin price drops after they buy it.
