MY STORY
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 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.

No cheating.
No fabricating.

[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.
But also from that peak, she fell freely.

[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'.

[D’s Insight #7] You have won a long time ago – if you are playing the right game.
A professional golfer stands before the decisive putt.
He breathes.
Bends down.
Eyes on the path of the ball.
That is the final pit.
In the finals.
He hits.
The ball rolls.
Falls into the hole.
Everyone rushes onto the field.
Applause.
Celebration.
His wife bursts into tears.
He is surprised, asking:
"Did you win?"
Yeah.
He wins.
That hit is worth exactly one million dollars.
And he has no idea.
This is a true story told by Lanny Bassham — a specialist in mental performance.

[D’s Note #29] Not Knowing That I'm Dumb
I don’t know why, but there are days I wake up and realize:
"What’s up with you today, looking so innocently dumb?"
Yeah. Sounds strange but true. But thinking back, it's not too wrong.
It's not that I try to belittle myself. It's just that I once firmly believed that I understood quite a lot of things in life.
You don’t need to be as wise as Professor Cu Trong Xoay, but at least enough to confidently sit at the feast of life without feeling too out of place.

[D’s Market #152] The market does not reflect the truth – but reflects belief
by 0xdungbui
The market does not reflect the truth.
It reflects what we believe to be the truth.
Imagine: you see a rope in the dark and think it is a snake.
In reality, it is not a snake.
But if you are scared enough, you will run away.
If the whole village believes that rope is a snake, no one dares to approach.
That belief – even if wrong – has created a new reality.
In finance, "ropes turning into snakes" happen every day.

[D’s Market #151] Accumulating altcoins: When is it not too early and not too late?
The market is not clear on the bottom yet, but those who are patient right now can gather gems from the trash. Don't try to win the bottom-calling contest; choose the side that survives.
When should one take risks and accumulate altcoins? This question sounds simple, but it keeps many people awake at night. Unfortunately, this is one of those questions that doesn’t have a definite answer—only less risky options.

Insight #6 - A Flexible Mindset
by 0xdungbui
When thinking about mental health,
most of us would envision things that sound pleasant:
cheerful, calm, untroubled, unstressed.
In summary: the feeling of 'okay'.
But Dan Siegel — one of the leading minds in neuroscience and mindfulness — points out something even more important than positive emotions:
the flexibility of the mind.
He describes a healthy mind like a flowing river.

NOTE 132 - THE ENEMY OF PROGRESS
🎯 One of the most successful fund managers once said that what caused him to lose money was not the market – but the moment he thought he 'knew enough.' Complacency does not come after success. It comes because of success.
💡 Intelligent people often fall into this trap more. They believe that if they are right a few times, then they will be right next time too. But the market, work, or life – do not follow that logic. Those who go the furthest are the ones who maintain curiosity like on the first day.
🔑 Core message: Knowledge is not a destination. It is a process. And that process only continues if you are humble enough to admit: you do not know everything.
—
🧠 Open mind, easy to understand,
🚪 Closed mind, hard to clarify,
🔍 Know, do not be rigid in belief.

Market #150 - Cash, Bitcoin, and Personal Freedom in an Unstable World
A few years ago, I started withdrawing more cash when shopping. At first, I didn't think much about it—it was just a small habit. But over time, I realized this was not simply a financial action but also a gentle yet powerful statement about personal freedom.
Cash today is like a paper book in the digital age: outdated, simple, but absolutely private. When you pay with cash, no one knows who you are, what you bought, where, or when. In contrast, every electronic transaction leaves behind digital footprints that can be tracked, analyzed, and even abused. Cash is not only a means of payment but also a small shield protecting your privacy.

NOTE 131 - DON'T COUNTERATTACK QUICKLY IN TRADING
🎯 Losses make you want to do something immediately. But “counterattacking” out of emotion only makes things worse. It's not a strategy – it's a reflex of a wounded ego.
💡 Reacting to the market right after a loss is a very human instinct. But in investing, instincts are often the enemy. Decisions made from emotions almost always go against logic and strategy. The best traders are not those who never lose – but those who know how to stay calm after a loss.
🔑 Core message: Calmness is not appealing. But it saves you from making wrong decisions. Take a step back, review the plan – sometimes that's the winning move you can make.

Crypto and the Economy of Trust: Value Comes from Shared Imagination (Market 149)
In financial history, many ideas were considered quirky when they first appeared. They were often mocked, doubted, and seen as 'non-existent.' However, many of them became important financial tools simply because enough people believed in their value.
Take 'tracking stock' as an example. This type of stock does not give you actual ownership of any asset of the parent company. You also have no voting rights in any decisions. The only thing you have is a vague promise of benefiting from the performance of a specific division in the company. It may sound hard to believe, but this collective belief has helped many people become wealthy.

NO UNBEATABLE FORMULA [NOTE #130]
🎯 If there were an unbeatable investment formula, everyone would be rich by now. The market does not follow a script – it reacts, shifts, and sometimes is completely irrational.
💡 Warren Buffett has been wrong. George Soros has been wrong. Being wrong is not the issue. The issue is not changing. The investors who survive the longest are not those who are always right – but those who are willing to update their beliefs when the facts change.
🔑 The core message: The market does not reward stubbornness. It rewards those who know how to step back, reassess, and take action again. In investing, the ability to adapt is a strategy. There are no guarantees – except for your own flexibility.

D's Insight #5: 3 Minutes 59.4 Seconds
by 0xdungbui
In 1954, all knowledgeable people in athletics firmly declared that:
No one can run a mile in under 4 minutes.
That’s the limit of humanity.
Impossible.
Nonsense.
Don't dream.
Roger Bannister didn't care.
And then he did the unbelievable:
Run a mile in 3 minutes 59.4 seconds.
How did he do that?
No — not by "trying your best."
