Never give out your seed phrases, even to family, just put it in your will incase you die.
I do agree with all things OP wrote except this one. Life is uncertain and we dont know when we will breath our last. Many bitcoins are lost just because there wallet owners die without giving key/seed or password to there next of kins. Even if you share things like key/seed or password to your next of kin make sure he/she can operate your wallet and use them.
In short, remain a lowkey person.
Cant agree more. There are nobody in this world who will be happy with your success rather people felt jealous because of others success. Its best not to share what you have achieved.
