Tham, Sân, Si, Mạn, Nghi - Five Evil Spirits That Cause Investors to Fail in the Cryptocurrency Market

When entering the world of cryptocurrency, many investors realize that the biggest challenge is not technical skills or strategies, but their own psychology. Buddhist philosophers once identified five mental poisons—greed, anger, ignorance, arrogance, and doubt—as the main obstacles to liberation. Strangely, these ancient concepts are perfectly suited to explain why many people fail at different stages of the market.

Greed: When Fear of Missing Out Leads to Poor Decisions

Greed is understood as attachment, always wanting more, and fearing missing any opportunity. In a bull market, greed manifests as investors never being satisfied with current profits. They keep hoping prices will continue to rise, prolonging their holding until the bubble bursts. The “fear of missing the peak” effect causes them never to know when to exit, ultimately suffering significant losses.

Anger: Resentment After Failure Leading to Impulsive Actions

Anger refers to the frustration and resentment that arise after poor decisions. When prices fall and investors see their assets evaporate, they often react emotionally: cursing analysts, gossiping about the market, or worse, banding together to cover losses. This is the most dangerous behavior in the early and middle stages of a bull market because it worsens the situation.

Ignorance: Lack of Knowledge as a Trap for Mistakes

Ignorance, or delusion, means being uninformed, lacking knowledge, and unwilling to learn. Many market participants do not understand blockchain technology or the fundamental factors affecting cryptocurrency prices. They follow the crowd, imitate others without thinking, making them easy victims of scams or abnormal market waves.

Arrogance: Overconfidence Turning Dangerous

Arrogance refers to pride, looking down on others, and believing oneself always right. After experiencing a few big gains, many investors start trusting their predictions, thinking they “understand” the market better than analysts or experts. Overconfidence causes them to ignore advice, mismanage risks, and ultimately suffer large losses.

Doubt: Lack of Decisiveness in Uncertain Waters

Doubt involves suspicion and indecision. This mental poison makes investors hesitant in critical decisions. When the market fluctuates, those dominated by doubt will never act, waiting for completely “safe” signals—which will never come. As a result, they always act too late, missing big opportunities out of fear of mistakes.

To succeed long-term in the cryptocurrency market, investors need to recognize these five mental poisons and find ways to control them. That is the true first step of the journey.
