Made a hefty profit during the doubling market. Sold all 400k at the high point, instantly feeling a surge of comfort. Not long after, the market retraced, and I couldn't hold back, re-entering with 276k. After this move, I finally understood—taking profits means winning half the battle. But to be honest, true experts are those who can be ruthless about exiting and also know how to ambush at low points. Looks like my journey as a 'small retail investor' is still very long.
