Yes! You need to protect your wallets against any possible theft or hacking. You must protect your private keys and wallet passwords. This is a must for everyone, else your coins will be stolen.
The frequent warnings of ensuring you protect your private keys from anyone seems to have eaten too deep into almost everyone of us in cryptocurrency. Some of us have forgotten certain realities of life and cryptocurrency wallets which I want to warn you about. My warning is mainly targeted at anyone who has a family, or at least, a child. You must leave a means or trace that your family will be able to access your wallets when you are gone. I mean when you are below 6ft. Each one of us will die some day. No one wants to hear this, but it is the absolute truth. If you suddenly die today with your secret keys and passwords unknown to your family, your coins are lost forever. Your crypto wallet is not a regular bank, so no way your family can claim your many crypto wealth online.
Don't be selfish. Your family or wife or children must not suffer when you have so much Bitcoin or other coins trapped in an inaccessible online wallets.
Remember your family and loved ones.
You have a very strong and uneasy decision to make today.
Death, where everyone goes in the end.
If you really trust the person, you can can let them know your key instead there something happened to you. We all know that it is important to keep secret your private key so its better to give it to your trusted family member that will protect it once there something happened to you and also that person know crypto and how to use it.
