A decline is not a risk; a decline is a process of reducing risk. Risks arise from increases, while opportunities arise from declines.
Therefore, your actions during a decline determine your mindset during an increase. If you don't buy during a decline, you will chase after increases, and chasing increases has a high probability of getting trapped.
If you get trapped during a decline, you will cut your losses. It's a cycle. Instead, a good start is: continue to buy in batches during declines, and take profits in batches during increases. Continue to buy in batches during declines, and take profits in batches during increases.
