Whatever we do to prevent loss of access to our cryptocurrency wallets, this will still happen for various reasons within our control and beyond our control. People are all different, so mistakes, absent-mindedness, negligence and even various accidents will cause you to lose access to cryptocurrency. Now there is a lot of talk about the growing capabilities of quantum computers, including the fact that in a maximum of ten years they will be able to crack the security codes of cryptocurrencies. This, of course, is a very big threat to the very existence of cryptocurrencies. But at the same time, it will be a chance to restore access to previously lost cryptocurrency wallets.
