Did not make money when prices were low, but felt like making money when prices were high
This is not a matter of price, but an illusion of emotion and liquidity.
Low Price: Low risk, bad sentiment, poor liquidity - hesitant to invest heavily
High Price: High risk, good sentiment, high liquidity - prone to impulsiveness
To truly make money:
Have the courage to invest heavily in times of low sentiment, and have the courage to take profits in times of high sentiment.
