May I ask, if the company's employees follow him and also decide to receive their salaries in bitcoin, what benefit does that bring to them? What are the benefits of getting paid in bitcoin for your main job?

I don't know what the benefits are but the first downside I see is that his or those employees' privacy will be significantly affected. Because company or someone can track what their money is used for, where it's spent...and to me that's an invasion of privacy. Would you feel comfortable if someone knew your bitcoin wallet address and tracked your every move?
