Can we also show our bitcoin key to someone closer, maybe love, spouse, next of kin?
Better still between someone; who introduced and taught you about bitcoin, a friend or family member and your children who's most preferred and reliable person to give out our information about your bitcoin?
It's generally not recommended to share your Bitcoin private key or any other sensitive information with anyone, including your loved ones or family members, unless it's absolutely necessary. Your private key is essentially your password to access your Bitcoin, and if someone else has access to it, they can potentially steal your Bitcoin or misuse it.
However, you can share information about your Bitcoin with someone you trust, such as a close family member or friend, without actually sharing your private key. For example, you can tell them about your investment in Bitcoin, how you manage your Bitcoin wallet, and your overall strategy for buying, selling, and holding Bitcoin.
If you want to ensure that your Bitcoin is passed on to your loved ones in the event of your death, you can consider setting up a legal will or trust that includes instructions for how your Bitcoin should be transferred to your heirs. You can also consider using a multi-sig wallet, which requires multiple private keys to access your Bitcoin, and give one of the private keys to a trusted family member or friend.
Ultimately, the decision to share your Bitcoin information with someone is a personal one that should be carefully considered based on your individual circumstances and the level of trust you have with the person in question. It's important to remember that once you share your private key or any other sensitive information, you lose control over your Bitcoin and the risks associated with it increase.
