From Two Sandwiches to Survival Discipline in the Crypto Market

Have you ever found yourself entering a trade right at the peak? Thinking you’re buying the dip, but instead, you’re buying halfway up the mountain. Watching your account shrink day by day, feeling hopeless and suffocated.
I’ve been there. It was even worse.
In 2017, I lived in a 10m² room in Hanoi, with moldy, peeling walls. I had just over 100,000 left – my last bit of money. I stood in front of the eatery downstairs, pacing back and forth three times, finally only daring to buy two bánh mì. That feeling, I will never forget for the rest of my life.
Eight years have passed, and I can’t say I’m financially free. But at least, I’m still doing well in this market and can help some brothers find their direction. Not because of luck. But because I paid my tuition with real money, with painful slaps from the market, in exchange for a few hard-earned principles.
Today I share the most practical lessons.

1. Don’t FOMO When Prices Spike – The “Invite to Trap” of Whales
   My most painful lesson was jumping into a coin after a few days of doubling. Good news everywhere, the community cheering, emotions soaring. The result? I was standing on top of Everest.
   Later, I understood: those vertical spikes, lacking foundational accumulation, combined with relentless media coverage – mostly looking for someone to “hold the bag.”
   Danger signs often are:
   After a strong spike, the price stagnates at the peak but doesn’t create a new high. Suddenly a large red candle appears with volume 2–3 times normal.
   That’s usually the final signal before big money retreats. When you see this sign, don’t hesitate.
2. Sideways at Highs is More Dangerous Than a Sharp Drop
   Many fear a sharp drop. I fear… sideways movement at the peak.
   In 2019, I held a hot coin. It stagnated near the peak for nearly two months, with a narrow range like a “dead fish,” and trading volume dwindling. I thought it was accumulating for another jump.
   The result was a straight drop of 50%.
   The lesson learned:
   When the price is too far from important moving averages (like MA20), liquidity weakens, and the market is quiet – that’s not accumulation, but money is quietly retreating.
   In this situation, my system triggers risk management: exit first, observe later.
3. True Bottoms Don’t Come from Hype, But from Endurance
   They say: “When others are fearful, be greedy.” But try being greedy in a crash like on March 12, 2020?
   I once tried to catch the bottom too early because my hands were faster than my brain.
   After reviewing many cycles, I recognized the common signs of major bottoms:
   Trading volume shrinks significantly. Price stagnates in a narrow range, with the market losing interest. Then a few small-bodied green candles appear, with moderate volume – like water simmering to a boil.
   True bottoms are often “brewed” in boredom, not in the sound of slogans.
4. Volume is the Oxygen of the Market, Capital is Your Lifeline
   K-Line can mislead you. But volume and big money flows are hard to fake over time.
   Trading must follow “volume,” not emotions.
   And more importantly: never go all-in.
   My principle: in all circumstances, the total active position should not exceed 50%. The rest is for backup and maintaining a strong mindset.
   For example, with a MEME coin that surges, I only enter when it breaks resistance with high volume and a clear trend. When the trend worsens, exit immediately. I don’t aim to catch the bottom to the top – I only take the safest middle part. Sleeping well is the real profit.
   Conclusion: Survive Before You Want to Get Rich
   In this market, experienced people make money from inexperienced ones. The sober-minded earn from the emotional ones.
   Eight years from two bánh mì to today, I don’t have a miraculous secret. Just enduring more, summarizing more, and being more disciplined.
   If you want to go far in crypto, don’t look for “a double-up opportunity.” Build a system, manage risk, and learn to wait.
   Knowledge is your greatest asset.
