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.

#BTCReclaims79000 
BTC — Where & When Is the Next Daily Support?
Bitcoin is trying to reclaim $79K, but so far, I still don't see a strong signal that BTC is ready to break and hold above $81K.
Again, this week feels like a waiting game.
Based on the chart structure I see, BTC is still moving inside an important range.
So the main question is not only:
“Can BTC go higher?”
For me, the bigger question is:
“Where and when will BTC find the next strong Daily support?”
🌎 MACRO — WHAT COULD TRIGGER THE NEXT MOVE?
🇺🇸 NFP — Friday
The August U.S. Nonfarm Payrolls report will be released on Friday, September 4.
This is one of the most important data releases this week because it can affect:
Jobs → Fed expectations → Yields → Liquidity → BTC
🏦 Fed Rate Decision
The next Fed decision will also be an important catalyst this month.
The Fed is still very data-dependent, so upcoming economic data could change expectations for rates.
💰 Bitcoin ETF Flows
ETF flows are still important for watching institutional demand.
We saw a large ETF outflow recently, but one day is not enough to confirm a trend.
If outflows continue, however, it could put more pressure on BTC.
🇺🇸 CLARITY Act
Progress on the CLARITY Act could also improve sentiment by giving the U.S. crypto market more regulatory clarity.
📊 4H — STILL CONSOLIDATING
On the 4H chart, BTC is still consolidating around:
🔵 $77K–$79K — Current range
📍 $76K–$77K — Support
🔴 $79K–$80K — Resistance
For now, I don't see a clean trade setup.
BTC is still moving inside this range, so I don't want to chase the middle.
📅 DAILY — STILL IN THE SAME ZONE
On the Daily chart, BTC is still inside the bigger:
$77K–$80K zone
This area remains important as both support and resistance.
So far, I don't see a major change in the Daily structure.
BTC reaching $79K again does not mean we have a breakout.
For me, I want to see:
Break → Hold → Confirm
before becoming more aggressive.
⚠️ THE AREA I'M WATCHING — DAILY FVG
The most interesting part of the Daily chart for me is the Fair Value Gap around $75K–$72K.
The FVG is still open.
This does not mean BTC must fill it.
But if the current support breaks, this area could become important for the next reaction.
That's why, right now, I am more interested in:
Finding the next Daily support instead of chasing $79K.
🎯 TRADE SETUP A — DAILY / LONGER TERM
For the Daily chart, I'm mainly watching the open FVG area.
📍 Support 1: ~$73K
📍 Support 2: ~$70K
📍 Support 3: ~$68K
🎯 Taking Profit 1: $75K–$76K
🎯 Taking Profit 2: $77K–$80K
This does not mean I expect BTC to definitely fall to $73K.
I'm simply watching these areas for a better risk/reward setup if BTC comes down.
⚡ TRADE SETUP B — SHORT TERM
For short-term trading:
📍 Support 1: ~$76K–$75K
→ I want to see another test
📍 Support 2: ~$72K
🎯 Taking Profit 1: $77K–$77.5K
🎯 Taking Profit 2: $78.5K
But honestly, the current structure is not very attractive for short-term trading.
For me:
WAIT > FORCE A TRADE
🧠 MY VIEW
My previous BTC trade setup is still valid for now.
I'm not changing my view just because BTC is testing $79K again.
Right now, I'm mainly looking for new support, especially on the Daily chart.
The levels I'm watching:
$81K → Breakout confirmation
$79K–$80K → Resistance
$76K–$77K → Current support
$75K–$72K → Daily FVG
$70K → Secondary support
$68K → Deeper support
The most important thing now is the reaction.
I want the Daily chart to show me where buyers are actually willing to defend.
Until then:
No FOMO. No forced entry.
For long-term investors, BTC can still be interesting for DCA depending on your strategy and risk tolerance.
But for short-term trading, this current range is still quite risky.
DYOR.
For now, I'm waiting for the Daily chart to show me the next strong support before taking another trade.

Ethereum ETH (4-hour chart) Market Analysis
 
The 4-hour timeframe has formed a large high-level consolidation range. The upward rebound structure on the daily and weekly charts has not been damaged; the current phase is a consolidation and shakeout midway through the rise.
In terms of wave structure, price is currently switching back and forth within the consolidation range. Two scenarios: first complete a downward pullback to test the key support at 2350 and complete this round of corrective waves;
After holding the lower support, complete waves 3-4-5 and move upward to challenge the previous-high resistance at 2566 at the top of the range.
The current price is in the middle of the consolidation range, and the short-term direction has not yet been formally chosen.
 
Short-term trading strategy:
​
Wait for a pullback to the 2380-2365 support zone and lightly position for a rebound, with a target around 2440. If it breaks through, look toward 2470-2490; if it fails to break through, take a short position. If it directly breaks below 2350 on heavy volume, abandon the long strategy.
​
Bitcoin BTC (daily chart) Market Analysis
 
The daily perspective is very clear: after this round of rallying, major players entered the market to accumulate, and price is now confined within the large 75800-81500 range. This range is expected to continue consolidating for some time, digesting the previous gains and accumulating chips.
Historical price action can serve as a reference: on the previous two occasions, major players carried out intense shakeouts, completed a chip exchange, and then initiated major trend moves. At this stage, the conditions for either a direct one-sided surge or an immediate collapse are not present; wide-range consolidation and shakeout remain the primary trend.
 Strong resistance at the top of the range: 81500
​
Strong support at the bottom of the range: 75800
​
Intermediate short-term resistance: 79200-79800
 
Short-term trading strategy
 
Pull back to the bottom of the 76100-75800 range and go lightly long after stabilization. Once a daily candle closes below 75800, the structure of this range will be broken, and no further long positions should be taken.

$BTC Entry: short around 772-776, stop-loss at 781, target 763-740
773 was the repeatedly tested dividing line between bullish and bearish momentum, as well as the core support level of the purple moving average. I marked this line out for everyone yesterday—the downside would open up once it was broken. This level has now been decisively breached, with support directly turning into strong resistance. Overhead trapped positions are exerting pressure, making it impossible for rebounds to establish a firm footing. The short-side move has officially entered an accelerated phase.
The market is following a very smooth downward cycle: rebounds are pressured and retreat upon reaching resistance, while breaks below support produce new lows. Highs have steadily declined from 81500 to 793, 782, and 775; lows have also fallen in tandem. The descending channel is complete and smooth, with extremely strong trend continuation. Trading in the direction of the trend offers a high win rate.
