Portfólio de Reequilíbrio | Do Meu Diário: 2020–2025
Episódio — Fantom: De Cadeia Fantasma à Era Sônica
Saudações a todos os leitores da Binance.
No meu artigo anterior, compartilhei anotações e perspectivas sobre uma das moedas dentro do meu portfólio de reequilíbrio, Polygon, anteriormente conhecida como MATIC.
E hoje, minha jornada de diário de portfólio continua com outro ecossistema que uma vez se tornou uma das narrativas mais quentes durante a era DeFi:
FANTOM: O FLUXO NATURAL DA EVOLUÇÃO DIGITAL
No entanto, antes de entrar na discussão principal sobre a antiga era Fantom e a nova era Sônica, eu gostaria de revisitar a “era das lendas” entre 2020 e 2021 — um período onde o mercado cripto começou a mudar drasticamente.

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.

Honestamente, sempre vi a Solana como um dos ecossistemas mais agressivos no mercado cripto. Pela minha observação, sempre que o momentum se torna bullish, o SOL tende a se mover mais rápido e com mais força do que a maioria das altcoins. Há momentos em que a expansão se torna tão explosiva que sinto que a ação do preço começa a entrar em um nível completamente diferente de energia de mercado.
Ao mesmo tempo, também percebo como a Solana pode se tornar sensível assim que o medo entra no mercado. Na minha visão, sempre que o sentimento muda ou a incerteza macroeconômica começa a aumentar, o SOL geralmente reage de forma muito mais agressiva em comparação ao Bitcoin. Essa volatilidade é exatamente o que torna a Solana tanto empolgante quanto perigosa ao mesmo tempo.

Isso é uma "Revisão de Estrutura e Consideração de Risco" – Não é um Sinal de Negociação
Hm… o mercado agora não está se movendo por causa de um único problema. Às vezes parece que é notícia de ETF. Às vezes são os rendimentos dos EUA. Às vezes é uma rotação interna de criptomoedas. Então, antes de tomar uma decisão de entrada, é melhor dar um passo atrás e reavaliar a estrutura.
Ativos de foco:
Bitcoin (BTC)
Ethereum (ETH)
XRP (XRP)
