If you were extremely wealthy (hundreds of millions or over a billion), you wouldn’t be famous; you would just be a very wealthy person (lottery, business, investing, high-income job, whatever). Would your extended family know you are wealthy, or would you be very vague around them and not flash your wealth?
Vague. The lower profile the better. Ideally, nobody except my lawyer, accountant, and fiduciary will know just how wealthy I am. Instead of having a driver haul me around in a tricked out SUV, I’ll drive a 10 year old Toyota sedan. Ideally, nobody would know I was rich until I died and my lawyer and executor started putting my estate through probate court. “What do you mean Uncle X had $400M in the bank? Why did he never say anything?”
Because I don’t want to deal with grifters and scammers and con artists and gold diggers and the like.
