A lot of questions have no answers, but only a few have the right answers to 95% of some questions. Well, let me start with
trust. Can you trust a person, either a friend, family or a relative, with 100% complete trust? Let me answer myself first? NO I can't. I can't trust anybody fully 100% anymore because I have seen some though cases.
However, almost all of us here have a fiat bank account and some of us have what we call a
personal identification number, which refers to an ATM pin that we use for withdrawal or sending funds out, so the question is a bit simple:
WHO DO YOU TRUST WITH YOUR BANK ATM PIN? if you have a person that you fully trust with your ATM pin, can you also trust that same person with your seed phrase?
Its kind a funny, but two of my brothers, and 1 cousin do know my ATM pin, the reason is I keep nothing in my bank account haha

and the reason of not sharing the seed phrase is, I kept all of my funds in crypto. Well, I did wrote seed phrase somewhere and have told my youngest brother about it just in case of sudden death or unexpected events. Otherwise, I will also not trust anyone.
And in fact we should not, a recent scam occur with one a friend, who is scammed by his friend, and the scam was around 85 lac ($30623.96), well, if the amount would not be gone, then he could buy 1+ BTC easily at the current rate. The thing is, he trusted his friend with his bank and allowed him to use it and he withdrew all the funds and flew away to Malaysia, the thing is he was his friend for the last 15 years.
I learnt a lot from this, but still scared of the world out there, we can not predict what is going on the other's head, even though, you are so close to them.
