The answer to this question is simple but if we think deeply we can understand a lot. In today's era, if we talk about the word trust, we will always get its negative aspects, i.e. it is very difficult to trust someone now. Although there are still many good people in this world who deserve to be trusted, this cannot be thought all cases. And the number of those believers who can keep faith is almost limited. But in managing life, we must trust someone. I don't want to give my personal ATM PIN number to anyone just out of trust because I don't want to leave anyone under suspicion. I will not give my seed phrases to anyone. But there is no way without giving it. We have to trust someone and give that phrase, otherwise there will be no ownership in case of an accident. Inheritance we must trust someone.

Trust is such a big word. It's hard to gain someone's trust to that extend of sharing pin and seedphrase. You can't do that to anybody even if you'd say you trust them. But in my case, some of my family know my bank pin since sometimes they'd be the one who'll withdraw some money from my account. Like my mom. Of course I trust my mom, and even if she'll take some of the money (with my knowledge), I know she'll use it for the family's expenses. Also my gf knows my pin. As for my seedphrase, I share it will my gf because she helps me with crypto related stuff. I share it with her because if ever I can't find where I keep my phrase, I can ask her. Others might won't agree with this since they might think it's too early to share such private info when you're not even married yet but it's just that I trust her. It all depends on how we trust the people around us. If you can trust them with such things.

It's really hard to trust someone these days especially if you know their background. Once you learn they did stupid things before, you may really have to think twice before even entrusting some funds. If you have a kid it makes sense that you trust your wife since she will also take care of your kid once you suddenly just drop dead. She can at least get funds for them to live.

But in the current time when banks themselves are insolvent, I would run away from banks and just use BTC which I could also give the seed to my wife.

My answer to your question on trust is yes. I can trust my immediate family member and my wife. Based on my upbringing and my relationship with my sibling and what we have been through, I know that they are trustworthy. As for my wife, well of course she's my wife I got married to her in the first place because should anything happen to me she's the first person that will be called so yes I can trust her.

Yes. My wife and my immediate youger sibling. Aside these people, I do not trust any other person. My ATM pin and my seed phrase will be safe with them because they have knowledge about Bitcoin and cryptocurrency.

I don't think I can fully trust any of my friends or family or any relatives, because wealth is something that can sometimes cause confusion in a person's intentions, and even your close relationship can deceive you in greed. .Only yourself can be trusted with complete confidence. Earlier people used to trust each other and people used to be sincere,now people's trust is getting lost. This has happened to me myself, I trusted my close friend and did joint business with him, in which he cheated me for the sake of wealth.

I can give the ATM PIN of a bank account that doesn't have a lot of money to a close relative, but if the account has a lot of money, I will never give my ATM PIN to a close friend or relative. I feel like I can't trust anyone with my seed phrase, because it's always my long-term investment.So I'll try to keep my seed phrase as secret as possible, because it is possible for me to trust someone close to me and tell them and they can't protect my seed phrase.

Simple here, I never even trust a person who is going to ask me for my passwords whether it is of my wallet, my ATM, my bank, etc. I had to never give him any of them to a person.
Because all things are related to security and there should be no compromise on security, even one should not share with his family members, its friends.
But I'm confused about one thing, whenever I die how could be my password known something and my all money will be lost and no one will benefit from it? This could be shown to only one person that I have trusted the more. Otherwise, other ones who are asking for my password or any other I will never give them.

Personal details like ATM pin, seed phrases should not be shared with others but that doesn't mean you can not trust anyone with such information. One of my friends had my ATM and its pin number. Even he was holding one of my friends cards for a long time. We have never faced any issue. I don't want to share my seed phrase with that same friend which is true but if i do somehow i will trust him to hold that account. If you don't have someone like him in your life thats your bad luck bro. 

You can trust many people, but how everyone defines or achieves trust is individual to each situation. There is no hard and fast rule, besides identifying clearly untrustworthy traits which are obvious to most people. Only through life experience can and should you learn who to trust. There are different degrees of trust and even lawful backing if we're talking about business style arrangements. If you involve money in any relationship you have with another person, that can totally change the equation because some people behave differently when it comes to finances. Since you posed the question, you should not be disclosing your pin to anyone - because the banks prohibit it and there's no good reason to do so, you only cast unnecessary suspicion if you were to share it and something went wrong.

Nowadays, besides Pin-code, SMS confirmation is often required. Regarding trusting family members - any family member can accidentally tell or otherwise disclose the PIN code, so periodic change of the PIN code is highly recommended, if possible. It's just basic caution.

When I got married, my wife held my ATM along with the PIN and she was the one who managed all financial affairs because she was able to manage it well and for the good of my family. And another reason, because my wife is more frugal and also attentive when she wants to buy something.
And I also gave my seed phrase to my wife and I also taught her how to operate it, and the purpose is to anticipate if I die, because death is unpredictable and also knows no age.
In my opinion, our wife is the only person we should trust and be open about in any matter because she is the one who will be our companion until the end of our lives. And that applies to those who have a very good wife and we know her well overall and also love us very much.
