I have looked around, and the person I can entrust my seed phrase to, and it is safe for me at any time, is my mom. Any other person can have you betray the trust you have in them when they have calculated the amount you held in your custody. How to play a fast run on you to siphon your crypto money before you could be their target.
I think entrusting your seed phrase with your mom is the best decision you can actually make because the fact that she's your mom just makes everything interesting because she trustworthy and won't joke with your funds and this is something am sure about, moms are active the best, and I don't think there is any mother that will want to betray there own child, and some mothers don't even have idea what it is and even they do they don't seem to care much. And ot is even better to keep your assets a secret so that no one will even worry.
For my mom, he has the best interest of me in her heart. She won't like to what will cause me pain. She will keep my seed phrase, and won't disclose it to any of my siblings
Their is no mom that does not love there child and this is why I love the fact that we know what our mom is capable and if it is about the issue of your finance she will not want to do to much, there is enough reasons why your mom is the best option you can even think of, even your siblings might be worst than an outsider but your mom, she will do everything to keep it safe.
