Brave Rewards provider Gemini suspiciously asking for private data

Briefly describe your issue:

To get Brave Rewards, I registered with Gemini. Then I get an email from them asking for very private data w/c is dangerous in the hands of anyone other than myself. I want to report this email I got from them, here is pertinent part where they ask me to provide the ff: " * Your estimated net worth and a detailed description of your source of wealth

  • Is your source of wealth derived solely from employment income?
    • If not, is it also derived from other sources such as investment returns and/or inheritance?
    • For any stated sources of wealth, please also provide supporting documentation such as a pay slip, bank statement, tax return, or other relevant documentation."

What Operating System and Brave version are you using? (Menu --> About Brave)
