I agree that you don't need to tell everyone about your income, especially in crypto. Be humble and keep on stacking sats.
Through investors didn't give their private informations and they didn't tell anybody that they are and investors that they have money in Their wallets cause they will know how risky their life is if there are many people will know that they are storing some Bitcoins in their wallets. And also they will not sacrifice their money in their own risk. So they will keep Their mouth silence and always humble. They will act as a normal and we don't know that they are a big Time investor.
Keeping it secret is one way of protecting ourselves from risks and aggressive attacks from hackers. While we expose ourselves publicly, the more it attracts attention to evil people, and even some of our friends may think differently. Perhaps, we can live peacefully and the ease of not thinking somebody is watching us. If we keep our life low, people don't mind us but if they see us changing, that certainly makes them wonder what we did and what we make a living. We can make proud of ourselves of our great achievements silently, there is no need to tell others and let them know.
