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.
