In the world of financial markets, successful trading relies not only on knowledge and skills but also on how to face uncertainty, manage risks, and accumulate experience and opportunities through long-term trial and error.

In the book 'Antifragile', Taleb presents a profound point: the world is full of uncertainty, and those who can benefit from uncertainty are often the winners in the market. For any trader, these principles are not only guidelines for investment but also important rules for how to respond to market fluctuations and protect account safety.

Here, I will combine the ideas from 'Antifragile' to explore the five core principles of trading. These principles apply not only to traditional investment markets but also to the risk-prone cryptocurrency market today. Below is my understanding and practical experience summary of these core principles:

1. Uncertainty: Face risks, learn to accept uncertainty.

In any financial market, especially in high-volatility markets like cryptocurrency, uncertainty is always the main theme. As Taleb said: 'If you can predict the market a minute in advance, you can be as rich as a king.' But in fact, no one can predict future market trends, including so-called market experts and various analysis methods. The market is a complex system, and all analysis methods and tools predict the future based on past data, and no model or formula can exhaust all possibilities.

Therefore, as a trader, the most important ability is to recognize the uncertainty of the market. Many investors are swayed by various market analysts and news, blindly believing predictions and technical indicators while ignoring the randomness and volatility of the market.

Truly smart traders know that in the face of uncertainty, their strategy is not to try to predict the future, but to continuously adjust their positions and risk management to respond to market changes.

Taleb's 'Antifragile' emphasizes the value of uncertainty itself—antifragility. In simple terms, when the market fluctuates, some people can benefit from it because their strategies become stronger in volatility. This is not only a fundamental principle of investing but also the key to profiting in the cryptocurrency market.

2. Convex trading rules: Let profits run, cut losses.

To profit in the market long-term, the most basic requirement is to set reasonable entry and exit rules, known as 'trading rules.'

However, excellent trading rules are not just about finding the timing for entry and exit, but also about how to maintain flexibility during market fluctuations and adjust in different situations.

'Convexity' is a very important trading concept proposed by Taleb, whose core is to allow profits to have no upper limit while risks must be controlled within an acceptable range.

In simple terms, we need to 'cut losses and let profits run.' For example, a common trading rule is to buy when the price breaks through a key point, and sell when the price falls below a support level.

The key to this rule is that 'profits are unlimited' because the market sometimes gives you unexpected explosive opportunities. While 'losses are limited,' regardless of how the market fluctuates, you must set stop losses to avoid significant losses. Simple and effective trading rules are based on maintaining antifragility while maximizing returns and minimizing major losses.

3. Capital management: Ensure survival, avoid going all-in.

In the market, what matters most is not how much you earn, but how to ensure your account survives long-term. Especially in high-risk markets like cryptocurrency, traders often face rapid market fluctuations and extreme market events. At this time, excellent capital management plans are particularly important.

One of the core strategies is the barbell strategy. The core idea of the barbell strategy is to split funds into two parts: one part remains highly safe and stable, while the other part takes higher risks. In the cryptocurrency market, this means that 90% of the funds can stay in cash or low-risk investments, while 10% is used for high-risk speculation.

The advantage of this approach is that it limits the maximum loss, especially during severe market fluctuations or black swan events, traders will not lose all their assets due to a single failure. No matter how the market changes, maintaining the safety of funds is always the most important.

4. Repeated trial and error: Accumulate experience through failures and welcome opportunities.

Trading is a long-term game. Successful traders do not profit every time; often their win rate is even quite low. In fact, many excellent trading systems have a win rate typically between 30%-40%. This means that out of every 10 trades, 6 to 7 may result in losses.

However, as Taleb emphasizes, successful trading does not rely on every success, but rather on continuously accumulating experience through repeated trial and error. Each failure can help you understand the market better and comprehend how your trading system operates in uncertainty.

Through a lot of repeated operations, you will find that real profits do not rely on perfect predictions, but rather on making appropriate decisions at the right time.

Therefore, successful traders are often those who can patiently wait, are willing to experience failures and learn from them, rather than those who attempt to get rich overnight through quick wealth.

5. Good luck: Success requires timing, location, and people.

Finally, even if you master all the above skills, gaining ultimate success in the market still requires a bit of luck. Market fluctuations cannot be completely predicted, and many times, successful traders do not always profit solely based on their judgment and analytical skills; luck is also an important factor.

For example, during significant market events or black swan occurrences, lucky traders can take the right actions in time, while unlucky traders may suffer losses by missing opportunities. So, although we can reduce risks by improving our trading skills, in some cases, sudden market changes can become the key to determining trading success or failure.

Through the book 'Antifragile', Taleb shows us how to build a trading system that can survive long-term and continue to profit in an uncertain market.

Understanding uncertainty, establishing effective trading rules, managing capital well, accepting the trial-and-error process, and remaining humble in the face of luck—these five core principles are fundamental for any trader looking to profit in financial markets.

Therefore, in the cryptocurrency market, we need to build trading systems, continuously do the right things, and finally wait for our luck. In other words, after doing our part: do your best and let fate take its course.
