Don't regret not optimizing in time. Everyone will experience that feeling, including me. This market always operates in cycles: growth, adjustment, then purification. Big and small adjustments are inevitable to lighten the ship, eliminate the weak and prepare for a stronger rebound when recovering.
If your mentality is not stable, keep 30% of your capital. It is not only a safety buoy but also helps you stay calm and not get carried away by emotions. The market is harsh, but opportunities are always for those who are patient and have the right mindset.
