Do you think it is wrong if I asked a question on personal finance that could reveal my salary?
what question are you planning on asking ?
What is the best way to invest.
I guess it's not a big deal to to reveal your salary if you want to know your investment options. In fact, it's necessary.
Why do I need to reveal my salary if my question is important.
It is completely fine for you to reveal how much you make if you want to, it is only bad if you were to reveal someone else's salary. What you're doing here is ok.
