Hello, I'm Dung, in the crypto community, people call me 0xdungbui. Crypto trading, for me, is not just about numbers or charts, but a journey to discover my own nature. Every decision, every fluctuation in the market reflects my own patience, determination and belief. The challenges have helped me grow, not only as a trader but also as a person. Now, I want to share my story, along with the lessons and experiences I have accumulated throughout this journey.
[D’s Insight #13] Thực Hành Trong Bóng Tối – Công Thức Xuất Sắc Trong Mọi Cuộc Chơi
Ít ai biết, Leonardo da Vinci để lại hàng ngàn bản vẽ chưa từng được trưng bày. Không phải tranh chân dung hay thánh thần. Chỉ là những bản vẽ giải phẫu, dòng nước, bánh răng, cơ bắp — tỉ mỉ, lặng lẽ, không ai vỗ tay. Những bản vẽ ấy không được tạo ra để nổi tiếng. Chúng là luyện tập. Là bóng tối cần thiết để một ngày nào đó, ánh sáng có thể chiếu lên bức tranh The Last Supper. --- Hôm nay, thế giới tràn ngập ánh sáng: “Tỏa sáng rực rỡ!” “Đừng để ai làm lu mờ ánh sáng trong bạn!” Nhưng chẳng ai nhắc bạn về bóng tối. Về những buổi sáng 5 giờ, khi bạn dậy đọc sách — không ai thấy. Về bản nháp thứ 38 bạn viết lại mà vẫn chưa hài lòng. Về hàng tháng trời luyện kỹ năng mà chưa ai biết tên. Thế giới thích ánh sáng. Nhưng chính bóng tối mới tạo ra người có thể đứng vững khi ánh sáng tới. --- Kỷ luật là nguyên liệu. Ánh sáng chỉ là tác dụng phụ. Nếu bạn thật sự muốn thành công, đừng hỏi làm sao để được công nhận nhanh hơn. Hãy hỏi: “Mình có sẵn sàng luyện tập ngay cả khi không ai thấy không?” Như Kobe Bryant. Người không bao giờ bỏ buổi tập ném bóng lúc 4 giờ sáng. Không phải để khoe trên mạng xã hội. Đó đơn giản là… hệ thống sống của anh. Như Vince Lombardi từng nói rõ: “Chúng tôi thắng trận trong thực hành. Vì chúng tôi luyện những điều cơ bản nhiều hơn bất kỳ ai.” Ánh sáng không cứu được ai. Chỉ có sự chuẩn bị thầm lặng mới là điểm tựa thật. --- Chúng ta đang sống trong một thời đại muốn kết quả ngay lập tức. Học vài tuần — muốn "thành thạo". Viết vài bài — muốn xuất bản sách. Tạo content vài tháng — muốn xây thương hiệu. Thành công bị coi như một món hàng giao nhanh: Đặt là phải có. Nhưng mọi kết quả thực sự đều là chỉ báo trễ (lagging indicator). Nó đến sau — sau khi bạn đã đủ kiên nhẫn, đủ kỷ luật, và đủ tin vào quá trình. Không ai giác ngộ sau một buổi thiền. Không ai định hình giọng viết sau ba bài post. Bạn phải làm việc trong bóng tối — để khi ánh sáng tới, bạn không ngỡ ngàng. --- Xuất sắc không phải là đỉnh cao. Nó là kết quả tự nhiên của một hệ thống đúng. Bạn không cần thiên phú. Bạn cần một hệ thống. Một thói quen. Một vòng lặp hành vi được lặp lại — dù chưa thấy kết quả ngay. Thành công không phải đích đến. Nó là phản hồi tự nhiên của một vòng lặp đúng: Luyện tập → Phản hồi → Điều chỉnh → Luyện tập tiếp tục. Bạn không cần xuất sắc để bắt đầu. Bạn chỉ cần một hệ thống khiến bạn không thể không làm điều đúng — kể cả khi chẳng ai nhìn. Thế giới này là một sân khấu. Người ta xây dựng hình ảnh, chụp từng khoảnh khắc, kể từng chiến thắng — đôi khi, trước cả khi chiến thắng thật sự đến. Nhưng có một nguyên lý cũ vẫn luôn đúng: Sân khấu bóc trần bạn về mức độ chuẩn bị. Khi áp lực tăng, bạn sẽ rơi về độ sâu của thực hành — chứ không phải kỳ vọng. Bạn có thể giả diễn. Nhưng bạn không thể giả sự thành thạo. Chỉ thực hành thật mới tạo ra sự hiện diện thật. --- Bạn không cần ánh sáng lúc này. Bạn cần một không gian yên tĩnh. Một lịch trình kỷ luật. Một thói quen có thể lặp đi lặp lại mà không chán. Bạn cần luyện tay. Luyện tâm. Và lặp lại điều đúng — không cần ai vỗ tay. Lúc ánh sáng đến, bạn sẽ không bất ngờ. Vì bạn đã luyện cho khoảnh khắc đó từ rất lâu rồi. #0xdungbui
[D's Market #162] The last gap for investors is time
(When AI takes all the advantages – you still have one thing it can't steal) In the past, making money from the financial market… was like going into the woods to find fruit. Who is faster, who has brighter eyes, who knows the hidden corners — will reap the sweet fruits before others. Back then, information was scarce. Whoever has it – wins. Warren Buffett was once the best fruit hunter in that forest. Every day, he reads thousands of pages of reports.
[D’s Market #161] When the Internet Redefines Capitalism
We often think of capitalism as a solid system. Massive. Immutable. But in reality, it's like a big box — filled with different toys. And then the Internet appeared. Crypto emerged. The box was shaken up. --- Once upon a time, the world of finance and politics was in the hands of a small group of powerful people: The government. Banks. Large corporations. Want to join? You need paperwork. Must ask for permission.
[D’s Note #136] Why do we have everything but still learn nothing?
We are living in a rather strange era. There are all the answers, but I don't know what to ask. There are plenty of tools, but you can't really use many of them. There is a universe of knowledge in my pocket, but in my head, I still feel lost. In theory, I can learn everything in the world. But in reality, I find myself learning nothing. I once thought I was swimming in an ocean of knowledge —
[D's Market #160] Price is not always value: The most common psychological trap in investing
Have you ever bought an item just because it was more expensive than the one next to it – even though both are exactly the same? If so, you have been a victim of something called: High price bias. In the crypto world, the same thing happens every day. When Bitcoin reached 95,000 USD, everyone rushes to buy. But when the price was 30,000 USD, most stood outside, skeptical, worried. We are programmed to think that: High price = good. This may be true for a watch.
[D’s Notes #135] Knowing much does not necessarily mean living rightly
You might know how to read. But you may not have actually seen. You might know how to speak. But you may not know when to stay silent. You might know a lot of things in life. But still living in the wrong direction – every day. Rousseau once gently said: “Wisdom is not knowing everything, but knowing what is necessary to know.” One way to define wisdom – not based on the breadth of knowledge,
[D’s Market #159] When attention becomes the scarcest resource
The world once resembled a big river, flowing slowly and gently. As long as you put a big enough boat on it, all eyes will be on it. An Elvis Presley. A Marilyn Monroe. An early Bitcoin. But now it's different. That river has shattered into millions of small streams. Each branch pulls away a little of our precious attention. In the world of crypto, this is clearer than ever.
[D’s Insight #12] Holding the Door, Shaking Hands, and Things That Will Never Be Outdated
Fred Rogers, the host of Mister Rogers' Neighborhood, is famous for his gentleness and kindness towards children. But what I remember most is not the show he made, but the way he lived. Before every filming session, he would take the time to shake hands with each crew member — from the doorman to the backstage assistant. “I don't just make a show for children,” he said, “I live with that show,
[D's Note #134] Attention is the Original Currency of Life
People often ask me: "What are you spending your time on?" But almost no one ever asked me a more important question: "Where are you focusing your attention – and what is that quietly turning you into?" I used to think time was the most precious thing. Until Naval Ravikant dropped a bomb into my mind: "The currency of life is not money. Not even time.
D's Market #158 – When 'success' becomes an issue: Bitcoin and the paradox of recognition from the government
Each time receiving a significant recognition signal, Bitcoin is often celebrated as if it has just reached a great milestone. The community cheers when a big company buys in. When a fund announces it holds Bitcoin. And most recently: When the US government proposed creating a strategic Bitcoin reserve fund (SBR). But... Is this 'success' really something to celebrate? A simple historical lesson is always repeated:
[D’s Market #155] Trading: The Real Privilege in the Crypto World and in Life
On the journey of exploring crypto and oneself, I have realized one thing: Trading is truly a privilege. Sounds strange. But history has always been the clearest proof. Four hundred years ago, the Plymouth pilgrims crossed the ocean with dreams of wealth. What welcomed them was not gold and silver. But hunger and despair. They could not be self-sufficient as they initially imagined. Their existence
[D’s Note #21] Honesty is easy - sincerity is hard
I used to think honesty was a simple thing. No lying. No cheating. No fabricating. Like taking a test without looking at the paper next to you—simple and clear. Coincidentally, I read a quote from Richard Feynman: "The first principle is that you must not deceive yourself - and you are the easiest person to fool." At that moment, I felt a chill. Not because this statement is too new. But because it’s true in a... uncomfortable way.
[D’s Insight #9] Don't search for passion – follow your energy trail
Elizabeth Gilbert once stood at the peak of the world with the book Eat, Pray, Love. But also from that peak, she fell freely. People demanded the next novel to be worthy. But Gilbert couldn't write a single word. Not because of lack of talent. It's because the old flame of passion has gone out. Gilbert didn't try to find back her passion for writing. Instead, she followed the only thing that still had some energy: a small basil plant in the garden.
[D’s Note #82] I was wrong, but still tried to play the right role
There are times when I realize I'm not really investing in the market. I'm just… playing a role – called 'the one who was right.' On optimistic market days, I don't look for signals to exit my trades. I'm just looking for reasons not to sell. Just because… I once declared that I was right. And I don't want to embarrass that confident guy inside me. What about when the market is pessimistic? I'm not waiting for a new obvious opportunity.
[D’s Market #154] Greed is not bad – but who will design it?
Gordon Gekko once said: "Greed is good." But in the world of crypto, that statement sounds like the opening line of a tragicomedy. Looking back to the time, Memecoins appeared continuously like mushrooms after the rain. The thing to think about is not: "Is greed bad?" But: How can we operate it? --- Greed is not a new invention. It has existed since our ancestors were still wandering the Serengeti plains.
[D’s Note #12] Drive slowly, avoid flipping – survive first, then think later
There was a time when I was obsessed with winning. I want to win quickly. Win big. Win to the point that people look at it and think: "Oh, this guy can really play." Until the market gets in the mood. It gave me a slap hard enough. And I woke up. Realizing that: winning quickly is not the ultimate goal. Surviving – that is what is more important than anything. Not the kind of survival of just 'as long as I breathe.'
[D’s Market #153] Investing in Losses – How to Turn Weaknesses into Competitive Advantages
One of the strangest mindsets I've ever encountered on the journey of investing and self-development is the concept: "Investing in losses." Sounds absurd, doesn't it? Instinctively, everyone wants to avoid failure. When faced with something that makes us feel inadequate, the first reaction is always to find a way to avoid it. But the problem is: You cannot be stronger if you keep avoiding the things that make you weak.
[D’s Insight #8] Kind Consistency – Live Like a Vine, Not Like a Steel Bar
Jerry Seinfeld once shared an extremely simple tip for writing every day: A large calendar and a red pen. Every day after writing, he marks an X. The only goal: Don’t let that chain of Xs break. No need to be excellent. No need for inspiration. Just one X every day. That small chain of Xs — repeated, quietly — becomes his huge career. But many people misunderstand this secret.
[D’s Note #24] A mistake doesn’t kill you – but a chain of mistakes does
One time, I lost 15%. Instead of doing what a clear-minded trader would do (cut losses, go out for coffee), I think I’m smart enough to 'make up for it' right away. I don’t understand why, but when I look back at it, I see: This mistake will disappear if I create a bigger mistake. Like how a stain on a shirt can be hidden if I… pour more coffee over the entire shirt. And so, from an initial mistake, I became an excellent screenwriter for the multi-part film titled 'Self-Destruction'.
