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.

September 4 BTC ETH Market Analysis
BTC
Yesterday, I told everyone that there would be a rebound at the one-hour level. When we looked at the market this morning, it had rebounded as expected, with Bitcoin rising to around 82,300 before pulling back. The 82,300 level is also a resistance level on the weekly timeframe. Only by holding above this level can we look for a larger-scale rebound.
The market will definitely see major volatility today because tonight we will get the nonfarm payrolls data. The market has already rebounded in advance. From the daily timeframe, we need to note that this move is a sharply rising departure leg, so as long as it fails to hold above 82,300, we need to watch out for risks.
Personally, I believe the risks at this level outweigh the opportunities, because both the daily and weekly timeframes are about to face resistance.
Support: 79,000–76,000
ETH
Ethereum’s rebound in this move was not as strong as Bitcoin’s, but it has still returned to 2,530, the level where we previously opened short positions. At the current level of 2,530, as long as it fails to hold effectively, we need to watch out for risks on the daily timeframe.

The daily trend is bullish, with the market gradually moving higher amid strong consolidation. Lows continue to rise, the price center keeps shifting upward, and the medium- to long-term bullish structure remains solid. Market trading sentiment has recovered, incremental funds are entering successively, and the upward pace is steady and healthy.
On the four-hour timeframe, bullish momentum continues to be released, with solid buying support. The price is steadily climbing along the ascending channel and has not yet reached the key resistance zone. The short-term upward channel remains intact, leaving considerable room for further gains. Judging from indicators across multiple timeframes, the probability of the market continuing to move upward in a bullish trend is relatively high.
Strategy:
Go long on BTC in the 80000-80500 range, target 83000

September 4, Friday, Gold. Good morning, everyone!
Gold surged last night and touched a high of 4511, but its upward momentum has clearly weakened. It is now oscillating at high levels and taking a breather.
On the 4-hour timeframe, the overall strong rebound structure remains unchanged. The lows continue to move higher step by step, and the bullish structure remains intact, though momentum has weakened somewhat after the surge.
On the 1-hour chart, the upward rhythm has already been disrupted. The price has fallen below the short-term moving averages, so it needs to pull back and build momentum before moving higher again.
The 30-minute indicators have also turned downward from high levels. The market is currently undergoing a consolidation adjustment, so don't blindly chase the rally.
Operationally, wait for a pullback into the 4455‑4435 range before going long. Look for 4520 above, followed by the 4550 target.
