Due to the fact that the price of bitcoin has grown significantly and they began to talk a lot about cryptocurrency, many of those who previously mined bitcoins or dealt with them in another way, but did not attach much importance to them, now remember their forgotten wallets, and also take measures to access to them. Therefore, some wallets are now suddenly reviving. It is unlikely that those who knew about them and had access to them for so long expected a significant increase in the price of bitcoin. Although, perhaps, such isolated cases also exist.
