Por que comprar Bitcoin(BTC)?

O que é Bitcoin? O nascimento do ouro digital descentralizado
O Bitcoin (BTC) foi introduzido em 2008 por Satoshi Nakamoto e lançado oficialmente em 2009 como a primeira criptomoeda descentralizada do mundo. Ele permite pagamentos eletrônicos ponto a ponto sem intermediários, como bancos ou governos. Todas as transações são registradas em um blockchain público, garantindo transparência e segurança.
Como funciona o Bitcoin? Consenso PoW e tecnologia Blockchain
O Bitcoin opera em um mecanismo de consenso de Proof of Work (PoW). Quando Alice quer enviar 1 BTC para Bob, os mineradores competem para resolver problemas matemáticos complexos. O primeiro a resolvê-lo ganha novos bitcoins como recompensa em bloco e registra a transação na blockchain. Esse sistema protege a rede, mas resulta em alto consumo de energia e aumento da dificuldade de mineração.
Oferta de Bitcoin e mecanismo de redução pela metade
A oferta de Bitcoin é estritamente limitada a 21 milhões de moedas, o que o torna absolutamente escasso. A cada quatro anos, um evento de “halving” reduz a recompensa do bloco para os mineradores, retardando a criação de novos bitcoins. Isso reforça as propriedades anti-inflacionárias do Bitcoin e é um dos principais impulsionadores de sua valorização de preço a longo prazo. No final de 2024, mais de 19,7 milhões de bitcoins foram minerados.
Histórico de preços e impacto no mercado
O Bitcoin começou praticamente sem valor, alcançando $20,000 in 2017 and hitting new highs above $60,000 em 2021. Ele passou por uma volatilidade extrema, como o famoso “Bitcoin Pizza Day”, marcando seu primeiro uso comercial. Apesar de ter sido chamada de bolha ou fraude no passado, a crescente adoção convencional e institucional elevou sua capitalização de mercado para além de US$ 1 trilhão.
Razões e riscos para investir em Bitcoin
Hedge de inflação e armazenamento de valor: Oferta fixa e eventos de redução pela metade tornam o Bitcoin um ouro digital e um potencial ativo seguro. Alta liquidez: O BTC é negociado em todas as principais exchanges, permitindo uma fácil alocação de portfólio. Descentralização e Autonomia: Não é controlada por nenhuma entidade; os usuários têm controle total sobre seus ativos. Riscos regulatórios e técnicos: alta volatilidade, regulamentações pouco claras, preocupações ambientais decorrentes da mineração e serviços de pagamento limitados.
Visões céticas e perspectivas alternativas
Apesar de sua natureza revolucionária, a eficiência do Bitcoin como ferramenta de pagamento é baixa e os riscos regulatórios permanecem significativos. Alguns especialistas veem o Bitcoin mais como um ativo especulativo do que como uma reserva estável de valor. Os investidores devem avaliar cuidadosamente sua tolerância ao risco.

APR at $0.18—are you going to buy the dip?
Look at the surface first: a surge and plunge, leaving a complete mess.
On August 12, the official team announced a buyback of 5.3% of the total supply (52.8 million tokens), sending the price directly from the lows to double and surge to 0.4-0.6. Two days later, a huge red candle slammed it back to 0.14, a drop of over 60%. Social platforms exploded: “RUG!” “The team dumped!” But there is no hard evidence of an exit scam. The 0.17-0.18 range has been repeatedly tested, RSI has entered oversold territory, and trading volume expanded to massive levels during the plunge. It is either the bottom or an abyss.
First: the buyback is real, but “buyback” does not equal “price pump.”
The team spent real money buying back 5.3% of the supply from early investors, redirecting it toward community incentives and ecosystem development. As soon as the news came out, market FOMO went into overdrive—the price doubled in two days and peaked at 0.6.
But the buyback was from early investors, not the secondary market.
Whales successfully sold, and retail investors successfully became exit liquidity. Look at that wick from 0.6 back to 0.14—who dumped it? In any case, it was not retail investors.
Second: the fundamentals cannot support 0.6; even 0.2 is a stretch.
The total supply is 1 billion, with 278 million in circulation. The market cap is approximately $50 million, but the FDV is as high as $180-200 million. What does that mean? At the current price of 0.18, if the entire supply were circulating, the actual value would only be $0.09.
The protocol’s TVL is only $500k-$800k, and net protocol revenue over the past 12 months was only a few thousand dollars.
A few thousand dollars in revenue supporting a $200 million valuation—this is not investing; it is a faith top-up.
Third: the technicals tell you that retail investors trying to buy the dip have already been buried twice.
From 0.6 to 0.14, the drop exceeded 70%. Daily RSI has entered oversold territory, and a bullish divergence is beginning to appear on the 4H timeframe. It looks beautiful.
But every rebound to 0.19-0.20 comes with declining volume, indicating that no new capital is entering; it is all trapped holders trying to rescue themselves. The 0.17-0.18 area is the bulls’ final line of defense—break below 0.146 and the next target is 0.10; hold 0.17 and see volume increase, and there is a chance of reaching 0.25.
Bulls versus bears—you decide
On one side:
Buyback of 5.3% of the supply; the deflationary narrative remains
From 0.6 to 0.14, a 70% drop; RSI oversold
The Monad ecosystem has long-term potential (high-throughput chain + MEV narrative)
A market cap of only $50 million means a low cost to pump
On the other side:
TVL is only $500,000, with annual revenue of a few thousand dollars
FDV is severely overvalued ($200 million vs. actual revenue)
The buyback essentially allows early investors to cash out
The macro environment is weak, and small-cap altcoins follow declines but not gains
Key levels
Upside resistance: 0.19-0.20 → 0.22-0.25 → 0.30+ (previous high area)
Downside support: 0.17 → 0.146-0.15 (strong support) → 0.10-0.12
Trading strategy
Aggressive gamblers (short term):
Wait for volume-backed stabilization around 0.17-0.173 before cautiously going long, with a target of 0.19-0.20 and a stop-loss at 0.165.
Most people:  Wait for a bottom formation and a high-volume bullish candle in the 0.146-0.15 range before considering an entry.
Bearish approach:
If a rebound to 0.19-0.20 meets resistance on declining volume, cautiously try a short, targeting 0.17-0.15, with a stop-loss at 0.205.
APR’s current script—
It is exactly the same as those “buyback narrative + low TVL” altcoins from 2024-2025: announce bullish news → pump → FOMO → whales sell → crash → rebound → continued selling.
The buyback is real, but the people making money are early investors. The money you make is the portion someone else deliberately left on the table for you to see.
When a project uses a few thousand dollars in revenue to support a $200 million valuation, it is not worth that much—you are helping someone else hold the price at that level.
