Don’t share how much you have with others. This should be obvious, but there are people that may not be so excited for you. They may tell their friends, and sooner or later someone who you don’t know, who may have the capacity for violence, may decide you are an appetizing target. This is yet another reason to use a multi-sig setup. Even if someone obtained 1 of 3 keys, they cannot steal your Bitcoin. Concurrently, your Bitcoin can be backed up. If you lose your Bitcoin you can literally just magically get it back if you have back up, that's because your Bitcoin is stored on the blockchain. If you have a copy of your "seed phrase" you can regain access to all your Bitcoin no matter which wallet you use. Don't go blabbing your mouth to everyone about your Bitcoin stack.
Bragging about your wealth and what you own is not ideal and can cause you to forever regret that your actions if the news gets to the wrong hears or hands and they decide to act upon it. This is a very large space and you need to keep things in secret for the safety of yourself and those around you. They don’t need to get hold of you to steal from you, they can as well get someone close to you that you can’t afford losing and prompt you to do what they want and get away with those coins. As others have said, when you’re held at gunpoint and about to lose your life, you don’t need to hesitate into not giving up all of your savings for them, because that will be better for you than just giving up your life for money that can be gotten back again.
I agree with what you are saying, and it is right not to put the assets in just one wallet; they should also be put in different baskets; they should be in the hardware wallet,
in the non-custodial wallets, and in trusted wallet apps related to the crypto space we live in.
This should be the best idea for anyone while not still disclosing the amount of bitcoin they own. Diversifying your money into different wallets should be a necessity to avoid loss of funds all at the same time. Even at that, most of the wallets could be trusted ones and non-centralized wallet, anything can happen like loss of private keys or seed phrase that can make someone get access to your wallet. Never disclose your worth, it is better for you and most preferred as a bitcoin investor or enthusiast that you are.
