Keep stacking friends.
Never reveal how much BTC you have just keep your mouth shut and don't know.
It's common for people like that to be pretentious and just want to know about BTC holdings, so choose friends who don't ask that question because it will always be sensitive and even I avoid it.
If to friends just teach them how to understand bitcoin so that they understand and don't ask again.
Bragging is really something we should avoid, but I find people are too stressed about revealing their bitcoin holdings to loved ones. This makes me ask the question, how much bitcoin do they own that makes them wary and always suspicious of their loved ones? 100BTC or 1000BTC? I really want to know how much bitcoin they own for people who are willing to not trust anyone just because of bitcoin. Bitcoin is just money, do we need to take things more seriously?
That's their own preferences, we all have our own experiences and home environments even our loved ones, they don't even wanna reveal their Bitcoin holdings no matter how much they have. Imagine that you just tell them that you are involved in a cryptocurrency which they lack knowledge but automatically they would expect you that you are making money, from that they could either ask you for money or even worse try to steal it since there's already a lot of cases that even blood-related could do such illegal things for their own sake convenience. Remember that this world runs on money, a lot of crimes that have existed involve money, cause no matter how much you have even just a small amount of BTC, its still yours, so it is up to you to decide which you can trust and keep it secret.
