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.

Look, Bitcoin has taken off! It has broken above the previous high of 81k—is this move headed for 90k? Will CRCL continue to rise? Let’s take a quick look.
1. Let’s start with BTC. As shown in the chart, Bitcoin has indeed broken above the August high of 81.5k. That’s incredibly bullish, and Shuqin, like everyone else, has made big money too. But! I’m very concerned, because BTC actually still hasn’t broken through the true neckline high of 82.8k from May. The risk is still there! So what should we do now?
2. For now, I’m choosing a relatively conservative strategy. I plan to take profits on leveraged positions as prices rise, just in case. As for the more stable spot holdings, you can continue holding them, even all the way to the bull-market peak next year or the year after, because coins like BTC and SOL have already broken away from the bottom. I believe the long-term upward trend has begun, although there may be some short-term twists and turns.
3. If you’re more aggressive, you can also hold until around September 15. This rally was mainly driven by the positive impact of the Clarity Act. Once the positive news is priced in ahead of time, when the bill’s outcome is announced on September 15, the market may very likely have exhausted the good news and begin to pull back, probably for around two weeks. If prices have risen too high by then, I may also consider opening a short position to see how it goes.
4. In fact, our recent positioning has all centered around the crypto bill scheduled for September 15. One US stock we’ve been discussing in these past few videos is CRCL, because a large part of the entire crypto bill concerns stablecoins. Before Tether goes public, CRCL is the only leading company investors can buy, and it is also the bill’s biggest beneficiary.
5. So unsurprisingly, CRCL finally took off yesterday, surging nearly 20% in a single night. It feels amazing. Everyone can consider taking some profits at higher levels. In any case, you should exit no later than around September 15. Congratulations to everyone on this move—following Shuqin really means living large and enjoying the good life~

#BTCReclaims80K 
I think $82K  is the most likely test in the short term, but consolidation between $80K  and $82K  is more likely than an immediate breakout.
* Momentum: BTC rose very quickly from around $77K  to above $81,000.
* Short squeeze: The liquidation of more than $400 million worth of short positions significantly accelerated the move; therefore, it is not appropriate to attribute the entire rise to new spot demand.
* Macro catalyst: The more dovish message from Fed's Christopher Waller lowered expectations for a September rate hike from around 63% to 50%. This is significant relief for BTC.
* Critical resistance: The $81,400–$82,800 range. If the May peak around $82,800 is exceeded, the $85,000–$90K  region may come into play.
* Risk: If it fails to maintain stability above $80,000, profit-taking after the short squeeze could lead to a retest of the $78,000–$77,000 levels.
My scenario:
Holding above $80K  → testing $82K  → breaking through to above $85,000.
However, rejection around $82K  and several days of sideways movement would also be quite normal.
In particular, today's US employment data could influence the outcome of this scenario; if rate expectations turn hawkish again, BTC may struggle to hold above $80,000.
I would consider a daily close above $82K  stronger confirmation than the initial breakout at $82,000.
