The question of the possible recovery of lost bitcoins, as a rule, is associated with the new capabilities of quantum computers, which, as predicted, can solve this problem in a matter of minutes. The emergence of such computers is not as much a matter of the future as many believe. China is already shipping low-power quantum computers to schools to learn how they work. So soon they will appear in large quantities. Of course, cryptocurrency holders, and especially large holders, are reasonably worried about the safety of their wallets.
Therefore, it is absolutely possible to recover secret keys from wallets to which access has been lost. After all, bitcoin in this case does not go anywhere. Everything remains on the blockchain.
