9.If you lose your private key (Bitcoin wallet), you lose your Bitcoins.
You store your Bitcoins in a digital wallet. You can log in and check your balance. One thing, though, you have to be very careful when it comes to storing your password and key, which is what allows you to access your digital Bitcoin wallet. If you lose this access, youll lose access to your Bitcoin wallet and the amount you have inside.
It's thought that around 20% of the entire Bitcoin supply is 'lost', primarily due to misplaced or stolen keys, or laptops or computers that have been discarded.
This is one of the things that I don't like about Bitcoin. I think that a solution needs to be created for this situation. We should reach our wallets somehow when we accidentally lose our private key.
This key feature is essential to security. It gives a sense of importance to the wallet which helps people/users reminded that their private key is a very important thing that they need to secure properly. I don't think it's a problem that should be given a solution. This is part of decentralization. It's not like users aren't given a choice. There are various ways to secure a private key like for example, writing it down, printing it, or if you are crazy enough, tattooing to your body (not recommended of course).
