the answer I don't commonly see on here is one that is probably the best in this situation, which is:

Holding IBIT is way safer than handing over your keys to any individual in your life.

then just add some beneficiaries to your accounts. easy peasy

When you don't trust your family members, then it will be difficult to answer this question. I know my family members very well and I know what they can do after my existence from this earth, because sometimes we know what people can do when we are still alive base some things you have used to tried them in so many ways and they did not break the trust one day.

I agree with you that some people have breaken the trust some people have towards them, that is making them not to trust anyone in their family or someone else than to keep the seeds phrase secret forever from everybody, because they know what will happen when they get access to the seeds phrase.

Scenario 1.  You teach your family member about your Bitcoin, they end up stealing it, you sue them and hire a good lawyer to win your case.

Scenario 2.  You teach a good lawyer about your Bitcoin, they end up stealing it, you sue them and try to find a better lawyer to win your case.

Which is more likely to end up well for you?  Which is more likely to become a difficult lawsuit?

Hiring a lawyer sounds good, until you realize humans make errors, are sometimes vile and even people you thought were the most trustworthy can end up screwing you over.  Lawyers know ways around laws.  Family members may not.  Sometimes being less knowledgeable is better.  Lawyers may carve the path in a way so they are advantaged by grey areas of the law.  I would not trust a stranger only because they have a lawyer office.

When it comes to money then anything could happen on which even your family will be trying out to steal those coins from you without even thinking that you are all doing these things for them and thats why you are trying out to accumulate for it to become bigger or having that good profits. They are the ones who do still benefit out from that but stealing up those coins could definitely happen. Basing up into those scenarios above then dealing up a problem in towards your family will be giving out that kind much more emotional damage since it do involves your loved ones in compared with other people that you are suing. When it comes or in regarding about teaching your family about the basics about crypto and trying out to plan on how they will be able to access these funds once you do pass away.

Trust is built and earned and not just something that happens all of a sudden. Blood relatives can turn against each other for the sake of money, and if we are to put all the things that happen around the world in front, we can never be able to trust even ourselves.

There is no point in getting married to someone you don't trust, but then again, who are those wealth made for if you can't even trust your family with them and they can't access it when you are unreachable?

It's a risk that should be taken but should be reduced to the minimal by either trusting the phrase with your spouse without her knowing what it is and the passkey to someone else who also doesn't know where to get the phrase, and the instructions could then be given to a third party, either an institution, who will then later hand it over to the lawyer who will do proper reading if need be.

I am assuming you mean in terms of legacy..right? Otherwise I'm not sure this makes any sense.  I've written topics about this and talked about it many times on here, but everyone needs to have a "will" established ( https://www.investopedia.com/terms/w/will.asp ).  Now this is for the US, but I'm sure similar things exist in most countries.  Yes, you have no choice but to trust a good lawyer anyhow.  Most are going to do the right thing.  Not to mention they don't need to be used alone..meaning you can leave a will with them, as well as in bank safety deposit box, burry it and leave a note that you've told all your family to read at your death ( or your lawyer/their firm to read and then send to your family) set up a trust "control from the grave" and on and on... so it all depends.

I think that when it comes to family bonding, people will make the decision to trust their lawyer instead of trusting their family members.  But if you don't have faith in your family, I think there is no one in the world in a worse situation than that person. So I would say first improve your family relationships. Because in my opinion, most of what we do in the world is for our family members, meaning our future generations.
So, just like in the case of property in the world, I have also made a similar arrangement that my property, that is, my crypto assets, are given to my family members. Although they do not have access to them while I am here, I have told them that you will receive the acceptance of my assets from these places when I am no longer here. Remember, a lawyer is not your that close person, he is only doing your work for the money, and if you give him access to your money, I don't think you will always get good returns.

You are not really specific in what you mean, teaching your family member about Bitcoin would make them have knowledge about Bitcoin and they would want to invest in it, right? Now teaching a family member about Bitcoin and trusting them with your funds in Bitcoin, which one do you want an answer to? I don't trust any family members with my funds for now but I can teach them about Bitcoin and also Bitcoin is not fiat and I don't trust any lawyer too.

You shouldn't be too trusting with your kids, the more they grow up, the more they have new thoughts and sometimes contradict you because of the influence of their social environment. Some cases of endless disputes between kids and parents after they reach adulthood. Bitcoin continues to be developed to a level that as much as possible doesn't require anyone's trust (in term of honesty) so that it can reduce the impact of losses from cases like this, one of which is by using the multisig method.
