Wow, this is a wild story. I wouldn't wish anyone to have such relatives.
We really should not brag about our wealth, because most people will not be happy for you, but on the contrary, they will feel hatred and envy.
You will discuss your digital assets with others and if any of them are greedy for your assets, they will definitely try to put you in danger. In this case you do not discuss your bitcoin or any other crypto currency matter no matter how closely related you are. Don't walk the streets with the device you store your digital assets on as this can increase your risk. Always try to keep an eye on the security of your wallet.
