One solution to this could be to create a notepad where you can keep information about your funds that one person can access. In this case, that node will definitely be important and it is important to keep a trusted family member informed and educated on the use of those assets.

Especially educate your heirs and make arrangements so that they have access to your assets in the event of your disaster. In this case, if your heirs are not trustworthy, you can lose your assets. So you need to choose someone you can trust and who will repay your trust. I will never see the wealth I have accumulated throughout my life buried with me.
