A9 cryptocurrency guru personally teaches: Three trading thinking models to achieve stable profits Yesterday, I reunited with my friend from the cryptocurrency industry whom I had known for ten years in Vietnam (who was once a co-founder of a top mining pool). He is now a top trader with a net worth of A9. During this meeting, he shared without reservation three trading thinking models that have been validated in practical situations - enabling him to sustain profitability in volatile markets. After sorting, I would like to share these valuable insights with everyone 👇👇 In terms of trading techniques, in fact, everyone has learned similar skills. What are the K-lines, moving averages, patterns, indicators, and qualitative content all over the internet, It's just a matter of learning more and learning less, As long as you study seriously, you won't be much worse. But why are some people able to make stable profits while others repeatedly suffer losses? I used to think it was luck, but after being beaten by the market for many years, I gradually realized that what really widens the gap is the "way of thinking". An excellent trader may not necessarily know all the techniques, but they must have a mature trading mindset model. Today, I will share three thought models that most experts have used. Many people may think they are simple, but there are not many who can truly understand and use them effectively. 🚩 Model 1: Probabilistic Thinking - Trading is not about right or wrong, but about probability. The biggest misconception many people make when trading is to treat every transaction as a "right or wrong question": if it goes up, it's right; if it goes down, it's wrong. As soon as I stop losing, I start to doubt the system, and as soon as I take profits, I feel like I have exceptional talent. But true experts never look at trading in this way, because what they see is: in the long run, can I make a profit by using this logic 100 times? This is' probabilistic thinking '. They don't have to make profits every time, but allow losses, even habitual losses. As long as the profit to loss ratio is high enough and the winning rate is controllable, it doesn't matter if you lose 7 out of 10 times. Many beginners learn technology just to 'get it right every time', but experts do statistics, not mysticism. To put it bluntly, experts are not predicting the future, but playing a game with long-term advantages. You are not a god, and the market will not rise just because you are bullish. You are just making a choice with positive expectations and seeing if long-term execution can fulfill its value. This is the core of the first model - do not pursue what is right, but pursue whether it is worth doing or not. 🚩 Model 2: Marginal Thinking - It's not about whether the present is right or not, but whether it's worth continuing. After trading for a long time, you will find that simply "looking in the right direction" is not enough. What truly determines whether you can catch a wave of market trends is your sensitivity to "marginal changes". Taking the cryptocurrency industry as an example, Bitcoin has recently experienced a small upward trend, with a bullish moving average, a MACD golden cross, and a continuous bullish candlestick, which looks very strong. Many people will chase after more at this time. But if you look closely, you will find that in this wave of rise, the entity of each bullish line is shrinking, the trading volume is shrinking, and the price is getting closer to the upper track, but it has not broken through yet. These technical details are telling us one thing: kinetic energy is weakening, margins are weakening. You don't have to short immediately, but at least you need to understand that the "cost-effectiveness" of this market trend is getting lower and lower. Experts will not hold their positions with peace of mind just because the price is still rising. What they will focus on is whether the quality of this upward trend can be maintained? For example, on the daily chart, there is a trend of rising from the bottom, and the K-line is rising in a stepwise manner, which looks very healthy. But when you cut the chart to 4 hours or 1 hour, you will see that the follow-up strength after each breakthrough is weakening, the RSI indicator shows a divergence from the top, and the Bollinger Bands begin to close. These phenomena can be attributed to "marginal decay" in technical analysis. That is to say, although the price has not yet peaked, the efficiency, momentum, and space for the rise are all deteriorating. If you continue to hold multiple orders at this point, the cost-effectiveness will become lower and lower. If you are an expert, you will choose to reduce your holdings in batches or start observing reversal signals at this time. The essence of marginal thinking is the perception of "internal quality changes" in the market. It's not just a superficial increase that makes it strong, but whether the increase has strength, continuity, and whether it's "accelerating" or "weakening". Technically, there are many ways to capture marginal changes, such as: (1) Can the quantity be coordinated: increase, decrease, or decrease? (2) Momentum indicator: MACD column becomes shorter, RSI deviates. (3) Structural details: The high point rises but the low point cannot keep up, the bullish candlestick becomes shorter, and false breakthroughs occur frequently. (4) Rhythm change: After the band rises, it begins to oscillate horizontally, and even frequently tests the upper edge but fails. These things are no longer simply a matter of "right or wrong", but a question of "whether they are worth continuing". So what we need to do is not predict the top, but detect changes in momentum, manage risks in advance, or timely exit opportunities with decreasing cost-effectiveness. 🚩 Model 3: Anti fragility thinking - not avoiding risks, but utilizing volatility. Most people want to avoid risks when trading because no one likes to lose money. Losing money means losing, so it's best not to lose, not to withdraw, and not to liquidate positions. But the thinking of experts is the opposite, they are not avoiding fluctuations, but utilizing them. I have a deep impression. A few years ago, I talked about trading with a friend who works in the cryptocurrency industry. He said that his most comfortable state is not when the market is stable, but when it experiences violent fluctuations. Ask him why? He said that when he designed his strategy, he pre-set these intense and uncertain fluctuations. This surprised me greatly at the time, even enlightening me. Because I never knew that you could preset your own risks, no longer pursue perfection, but pursue a goal: even if I am wrong, I will not die; By the way, there is room to profit. This way, your trading system will have particularly strong resistance to attacks, and you will no longer be afraid of risks. The market changes too quickly, you can never be right every time. Today is the trend, tomorrow it may turn volatile, this week Bitcoin is one-sided, and next week it may rebound. If you have to guess right every time to make money, we will never go far. This is' anti fragile thinking '. To put it simply, the core of anti fragility is not to avoid market fluctuations, but to embrace and even exploit them. Many people in the cryptocurrency industry are most afraid of fluctuations after placing an order, afraid of being washed out, afraid of being hit with stop loss, and afraid of being shaken back and forth. But experts are not afraid, they will instead design the system to "only eat the part with high certainty" and filter out the rest. How to do it? (1) Firstly, it is a light position, never allowing one transaction to determine life or death. (2) Secondly, there is a clear stop loss point, where mistakes are made and left without dragging the waters. (3) Furthermore, it is important to keep profits open, losses are limited, and profits are multiplied. If you look back at many high-level bands, in fact, the moment of activation often fluctuates violently, and many people miss it because they are afraid of being shaken. But the anti fragility system of experts allows them to make small trial orders and small cuts during intense fluctuations. Once the direction is established, they can add positions and follow suit. This is not recklessness, but the structure allows, the system supports, and the profit loss ratio allows them to do so. They are not 'accurate', but 'able to hold on, run away, and eat'. Finally, I would like to say a few words You can spend many years polishing your skills, but in the end, you will find that what determines whether you can walk long is how you "view the transaction" itself. Experts are not particularly intelligent, but they have already jumped out of the mindset of 'wanting to make money every time'. They don't make profits by guessing market trends, but by relying on their own model thinking to steadily make money, with compound interest (fixed investment in BTC). So instead of changing strategies and chasing hot topics every day, it's better for us to calm down and figure out these models. They may not make you rich overnight, but they can help you go far and live long. And these are the underlying logic that truly relies on trading to make a living.
