Người Nắm Giữ Danh Mục Tái Cân Bằng | Từ Nhật Ký Của Tôi: 2020–2025
Tập — Fantom: Từ Chuỗi Ma Đến Kỷ Nguyên Sonic
Chào mừng tất cả các độc giả Binance.
Trong bài viết trước, tôi đã chia sẻ những ghi chú và quan điểm từ một trong những đồng coin trong danh mục tái cân bằng của tôi, Polygon, trước đây được biết đến với tên gọi MATIC.
Và hôm nay, hành trình nhật ký danh mục của tôi tiếp tục với một hệ sinh thái khác từng trở thành một trong những câu chuyện nóng nhất trong thời kỳ DeFi:
FANTOM: DÒNG CHẢY TỰ NHIÊN CỦA SỰ TIẾN HÓA KỸ THUẬT SỐ
Tuy nhiên, trước khi bước vào cuộc thảo luận chính về kỷ nguyên Fantom cũ và kỷ nguyên Sonic mới, tôi muốn quay lại với “kỷ nguyên huyền thoại” khoảng năm 2020 đến 2021 — một khoảng thời gian mà thị trường crypto bắt đầu thay đổi mạnh mẽ.

From My Journal: 2020–2025
As the crypto world approached 2020, the market began experiencing a massive shift in direction with the arrival of major public figures such as Michael Saylor, Elon Musk, Jack Dorsey, PayPal and several institutions openly discussing cryptocurrency and demonetization. To me, that was the beginning of a new era of public acceptance toward crypto.
Today, I see many new players and investors in this space focusing mostly on
AI coinsMeme ecosystemsUltra-fast liquidity rotationTrading based on short attention cycles
But for me, the COVID era was a legendary period for portfolio balancing holders. It was the era where BTC crashed close to 3k before eventually breaking through the 100k ceiling years later.
PORTFOLIO STRUCTURE
And in my opinion, that period was when old altcoins played an extremely important role inside portfolio structures.
Not necessarily because they were the most explosive assets and not because I believed they would dominate the market forever, but because they helped maintain balance and from my perspective, balance is one of the most underrated survival tools in crypto.
Back then, many small holders believed that surviving multiple market cycles was simply about choosing coins with strong reputation, popularity and influencer support. Personally, I never fully agreed with that idea. In my opinion, survival in crypto depends far more on:
Portfolio structureEmotional controlLiquidity managementRebalancing disciplineUnderstanding market rotation
After spending years inside this market, I slowly realized something important:
A portfolio does not survive because every coin constantly wins. A portfolio survives because its structure adapts faster than the market changes.
That realization completely changed my mindset toward crypto.
During the 2020–2021 cycle, I built much of my rebalancing strategy around old altcoins such as:
TRXADADOTLINKXRPFTMVETNEARTHORChainPolygon/MATIC
Although many of these coins were actually launched years before 2020, the COVID era was the period where their ecosystems truly expanded aggressively and became an important part of crypto market rotation. Back then, these ecosystems behaved very differently compared to today. From my observations, many of these coins moved within a connected liquidity rhythm.
Capital rotated between:
Infrastructure chainsInteroperability narrativesDeFi ecosystemsPayment-focused assetsUtility-based networks
And within my own portfolio, Polygon/MATIC eventually became one of the most important balancing assets. Not because it was the strongest coin and not because I believed it would dominate the market forever. But because, from my perspective, Polygon/MATIC possessed a unique balance between:
growth potentialliquidity strengthecosystem relevancecontrolled volatility
Back in 2020–2021:
Ethereum fees became extremely expensiveDeFi activity expanded aggressivelyNFT ecosystems explodedLayer-2 narratives dominated the marketscams and false promises also became widespread
And Polygon/MATIC was perfectly positioned during that moment. In my opinion, it was no longer just a scaling solution. It became part of the crypto market’s liquidity rotation system itself. Inside my portfolio, MATIC often acted as a bridge between:
aggressive growth assetsslower infrastructure coinshigh-beta volatility playsdefensive altcoin positions
And that made it highly effective for portfolio rebalancing. It was volatile enough to create opportunities. But still stable enough not to damage the overall structure of my portfolio and honestly, that kind of balance mattered far more than hype alone. However, crypto markets evolve aggressively. The longer I stayed in this market, the more major changes I started noticing.
New Layer-2 ecosystems began emerging such as:
ArbitrumOptimismBasezk ecosystems
Liquidity slowly became fragmented. Narratives moved faster. Attention cycles became shorter and at the same time, Polygon itself also started changing. From my perspective, this was the beginning of Polygon’s identity transition.
The market started seeing:
Polygon 2.0MATIC → POL migrationAggLayer narrativesecosystem restructuringinfrastructure maturity
From a technological perspective, Polygon continued building. But psychologically, market sentiment started changing and in crypto, sentiment can sometimes matter just as much as real utility and now I find myself asking an important question:
Can an old altcoin still remain useful for portfolio rebalancing after losing its position as a market favorite?
Personally, I do not think the answer is simple. From my perspective, Polygon/MATIC never really “died.” It simply evolved, The problem is that markets do not always reward survival.
Sometimes markets reward:
hypemomentumspeculationattention velocity
Meanwhile, mature infrastructure projects often continue operating quietly beneath newer and more popular narratives and perhaps that is exactly what Polygon/MATIC has become today.
Not a dead ecosystem.Not an abandoned chain.And not an irrelevant project.
But perhaps no longer the type of asset that naturally controls market momentum the way it once did. From my perspective, this is where rebalancing becomes extremely important.
Because portfolio rebalancing is not simply about chasing the strongest coin. It is more about understanding:
liquidity behaviorvolatility relationshipsecosystem rotationnarrative cyclesmarket psychology
And after surviving multiple market cycles myself, I believe these things matter far more than blindly chasing the next hype narrative.
When I revisit my old portfolio journals from 2020 to 2025, Polygon/MATIC remains one of the most interesting assets for me to analyze.
Not because it became the biggest winner, but because it taught me something extremely important:
A coin does not need to dominate the market forever to remain valuable inside a rebalancing structure.
And perhaps that is the real difference between:
chasing narratives and surviving cycles.

Thật lòng mà nói, tôi luôn coi Solana là một trong những hệ sinh thái hung hãn nhất trên thị trường crypto. Theo quan sát của tôi, bất cứ khi nào động lực chuyển sang xu hướng tăng, SOL có xu hướng di chuyển nhanh hơn và mạnh hơn so với hầu hết các altcoin. Có những khoảnh khắc mà sự mở rộng trở nên bùng nổ đến mức tôi cảm thấy hành động giá bắt đầu bước vào một cấp độ năng lượng thị trường hoàn toàn khác.
Cùng lúc đó, tôi cũng nhận ra Solana có thể nhạy cảm như thế nào khi nỗi sợ hãi vào thị trường. Theo tôi, bất cứ khi nào tâm lý thay đổi hoặc sự không chắc chắn vĩ mô bắt đầu gia tăng, SOL thường phản ứng mạnh mẽ hơn rất nhiều so với Bitcoin. Sự biến động đó chính là điều làm cho Solana vừa thú vị vừa nguy hiểm cùng một lúc.

Hm… thị trường hiện tại không di chuyển vì một vấn đề duy nhất. Đôi khi có vẻ như là tin tức ETF. Đôi khi là lợi suất của Mỹ. Đôi khi là sự xoay vòng nội bộ trong crypto. Vậy nên trước khi đưa ra quyết định vào lệnh, tốt hơn là nên lùi lại và đánh giá lại cấu trúc.
