Mortgage application - they brought it up

I thought this was interesting. I was applying for a pre-approval for a mortgage today and they asked me all about my assets. After talking about the value of my stocks, without me providing any clues, they brought up cryptocurrencies and if I had any. I lied and said I didn't, I don't think I needed to mention them anyways as my other assets are pretty healthy for the amount of loan I am asking. One reason I think they brought it up was that I look young.

I though it as neat, this is all becoming more normal.
