BUT if we're lucky enough, I would suggest that you keep that you're HODLing Bitcoin only to yourself, not even your relatives and close friends should know. Believe me, wealth doesn't entirely change the person who made the wealth. It changes those people around the person because they know he/she has made wealth.
In my personal experience the "wealth change" wasn't that much during last ATH, but if Bitcoin surges to $1 billion, I probably should go into hiding.
Indeed, it's not just Bitcoin that we need to keep secretive. We don't know who is who, and we also don't know who those that are close to us are; we just have to play it safe first before we think about praising ourselves. That's why in this forum, privacy protection is among the things that's highly advisable to holders.
Even if it's not Bitcoin holdings, it's important to always note that there are levels of wealth that we might be in possession of that we don't need to disclose to anyone. Because betrayal comes from envy, jealousy, and greed, if someone who is close to you knows that you are holding a huge amount of Bitcoin or some level of wealth, they can turn out to be the unknown enemy that we have been hearing about. If they can't harm you themselves, they will discuss you with the next person who will. Sometimes they won't do it because they want to take away all that you have, but because they just don't want you to have it.
I guess you are very right on this because a man secrets is what keeps him afloat from others. I would not be having some certain amount of BTC and then disclosing it to my friends because I want to show a sign of wealth that would be stupidity and a sign of immaturity as well.
