You are actually right I can recall having conversations with friends how we can freely and publicly discuss holdings and investments without paying attention to who might be listening to us and who might be hearing the conversation and what could be there intensions, and I think this happens because we feel like this persons can only get access to your account when they are exposed to your seed phrase but the truth is the first risk comes from you making a dangerous person conscious of the kind of investment you have and the amount of Bitcoin in your wallet because when this persons are exposed to this information of how much you have it makes them start to strategize on how to hack into your Bitcoin wallet.
Bitcoin security is not limited to keeping the key secret, but keeping your personal information secret is also a very important issue. No matter how much you trust people, it is natural for people to be greedy. Suppose you discuss your Bitcoin amount and buying habits in the midst of your friends' chat or on social media. It is not that everyone presents there will harm you, but if that information reaches someone else, it will not take long for danger to arise.
Someone can make you a target by finding out about your identity, financial status and daily movements. However, financial status is not the main issue here, security plays the most important role in your life. Even if you cannot access the wallet directly, you may try to collect Bitcoin through various greed, fraud, fake identity communication or intimidation, but we need to be most aware of this issue. Therefore, you should not disclose how many Bitcoins you have unnecessarily.
