I found that Little Red Book is truly an intelligence lowland in the investment world.

In January this year, the timeline was all about buying gold, some even borrowing money or selling houses to buy it.
In February this year, the timeline was all about trading US stocks. My wife said seeing others make money, asked me to open an account for her to do the same. I told her to open a demo account first, and if she made money, I'd give it to her; if she lost money, she'd give me half - essentially making her my counterparty.
So she carefully selected $NVDA at 205, $GOOGL at 340, $TSLA
at 400, and then this month it's all about Sino-Korean semiconductors and discounted old brand gold sold at resale - it's dropped from 98 discount to 93 discount, no idea how far we are from breaking par....
Investing is actually quite simple - no matter when you buy, just sell when there's a lot of noise about it on Little Red Book.
