A fren of mine recently talked to me about her investment philosophy, saying it was inspired by the book "The Art of Investment."

The core points are a few: don't guess blindly about the ups and downs, holding on is the key; bubbles come and go every year, what really matters is the underlying logic of valuation; when the opportunity arises, go all in without hesitation; if you're stuck, accept it, don't stubbornly hold on to historical costs—this is what truly tough people do.

She said she has been scolded terribly over the years, her account has also been in the red, and she has seen all kinds of personal attacks on social media. But she doesn't care: "Being black and red is still red; the more people criticize me, the more it proves that I'm on the right path." The harshest is the saying "Fortune favors the bold"; it's not just talk, but real money invested to verify it.

Ask her if she still believes in crypto? She laughed: "In ten years, BTC will break a million dollars. When we look back then, today's fluctuations will be nothing."
