Porquê comprar Bitcoin(BTC)?

O que é Bitcoin? O nascimento do ouro digital descentralizado
A Bitcoin (BTC) foi introduzida em 2008 por Satoshi Nakamoto e lançada oficialmente em 2009 como a primeira criptomoeda descentralizada do mundo. Permite pagamentos eletrónicos peer-to-peer sem intermediários como bancos ou governos. Todas as transações são registadas numa blockchain pública, garantindo transparência e segurança.
Como é que a Bitcoin funciona? Consenso PoW e tecnologia de blockchain
A Bitcoin funciona com um mecanismo de consenso de Prova de Trabalho (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 do bloco e regista a transação na blockchain. Este sistema assegura a segurança da rede, mas resulta num elevado consumo de energia e numa maior dificuldade de extração.
Oferta de Bitcoin e mecanismo de halving
A oferta de Bitcoin está estritamente limitada a 21 milhões de moedas, o que a torna absolutamente escassa. De quatro em quatro anos, um evento de "halving" reduz a recompensa do bloco para os mineradores, abrandando a criação de novas bitcoins. Isto reforça as propriedades anti-inflacionárias da Bitcoin e é um fator chave para a valorização do seu preço a longo prazo. Até ao final de 2024, foram extraídas mais de 19,7 milhões de bitcoins.
Histórico de preços e impacto no mercado
A Bitcoin começou praticamente sem valor, atingindo $20,000 in 2017 and hitting new highs above $60 000 em 2021. Tem registado uma volatilidade extrema - como o famoso "Bitcoin Pizza Day", que marcou a sua primeira utilização comercial. Apesar de, no passado, ter sido considerada uma bolha ou uma fraude, a crescente adoção institucional e generalizada fez com que o seu valor de mercado ultrapassasse 1 bilião de dólares.
Razões e riscos para investir em Bitcoin
Proteção contra a inflação e armazenamento de valor: a oferta fixa e os eventos de redução para metade fazem da Bitcoin um ouro digital e um potencial ativo de refúgio seguro. Alta liquidez: a BTC é negociada em todas as principais exchanges, permitindo uma fácil alocação de carteira. Descentralização e autonomia: não é controlada por uma única entidade; os utilizadores têm controlo total sobre os seus ativos. Técnica e riscos regulamentares: elevada volatilidade, regulamentos pouco claros, preocupações ambientais decorrentes da exploração mineira e utilidade de pagamento limitada.
Pontos de vista céticos e perspetivas alternativas
Apesar da sua natureza revolucionária, a eficiência da Bitcoin como instrumento de pagamento é baixa e os riscos regulamentares continuam a ser significativos. Alguns especialistas veem a Bitcoin mais como um ativo especulativo do que como uma reserva de valor estável. Os investidores devem avaliar cuidadosamente a sua tolerância ao risco.

I find that many new people entering the market often overlook an important detail on the chart—that is, what trading volume (vol) is, which I want to share with you today.
Vol (trading volume) simply refers to the total amount of currency that is bought and sold within a certain period of time. For example, if today there are 1,000 BTC traded, that is the vol for that day. It may sound simple, but it’s very important for understanding the true strength behind a price movement.
When you look at the chart, you’ll see colored bars beneath the price chart. What vol means is reflected through these bars—blue bars indicate high buying volume, and red bars indicate high selling volume. An easy way to remember is: blue = more buyers, red = more sellers.
Why should you pay attention to vol? Because it helps you distinguish real movements from fake ones. If the price is rising but the vol is weak, it may just be a temporary trick. On the other hand, when the price rises together with high vol, that’s a sign of a real and strong trend. I also often use vol to spot reversal points—when vol increases sharply at support or resistance levels, it often signals that the price is about to change direction.
Vol is not only an indicator; it’s also the “voice” of the market, telling you what’s happening behind those price numbers. Don’t just look at the price—listen to the voice of vol to understand the market more deeply.

Recently, I saw many people in the community asking about short selling—what exactly does it mean? In fact, this is a trading strategy that many beginners misunderstand. Let me share my understanding of short selling.
Simply put, short selling means you are bearish on a certain asset, profiting from a price decline by borrowing and immediately selling it. Imagine you find that a certain crypto asset is obviously overvalued, its price is soaring, but your analysis tells you a crash is imminent. This is when short selling comes into play. Instead of buying and holding, you take a reverse approach—borrow the asset, sell it at the current high price, and then buy it back at a lower price after the decline, with the difference being your profit.
When I first started learning about short selling, the biggest misconception was thinking it was a simple reverse operation. In reality, it’s much more complex than that. Leverage can amplify your gains, but it can also infinitely magnify your losses. Since prices can theoretically rise infinitely, your potential loss is also unlimited. That’s why risk management is so critical in short selling.
On a major margin trading platform, the process of short selling generally goes like this. First, you need to transfer collateral into your margin account, which can be done manually or by enabling automatic transfer. Then, borrow the asset you want to short, either by applying for a loan or using an automatic borrowing feature. Next, continuously monitor price movements, using stop-loss and take-profit tools to manage risk. When the price drops as you expected, you buy back the asset and repay the loan plus interest.
In my own practice, I found there are two ways to close a position. One is manual closing—you choose which assets to use to repay the debt, and the system will sell them via market orders. The other is setting up an automatic liquidation mode—you pre-place buy orders, and once they are executed, they are automatically used to repay the debt. This method is more friendly for lazy traders.
Let me give a real example. Suppose BTC is currently 10,000 USDC, and you expect it to fall. You use 10,000 USDC as collateral to borrow 2 BTC and sell them. Two weeks later, BTC drops to 7,000 USDC. You buy back 2 BTC at 14,000 USDC and repay the loan. After deducting fees and interest, you make a profit of 6,000 USDC. That’s a practical illustration of what short selling means.
But here’s an important point—position adjustment. How much you can borrow depends on your total collateral, the leverage multiple you choose, the amount already borrowed, and your account level. The maximum borrowing amount calculation formulas vary with different leverage ratios. I’ve seen too many people get forced liquidated because they didn’t understand this.
Honestly, although short selling sounds very attractive, the risks are no joke. Leverage can indeed amplify gains, but if the market moves against your prediction, losses can accelerate so quickly that you can’t react in time. Therefore, successful short selling really depends on three things: accurate market analysis, real-time monitoring of price fluctuations, and absolutely essential risk management discipline.
If you also want to try short selling, my advice is to start small, use stop-loss orders to protect yourself, and avoid over-leveraging. There will always be new opportunities in the market; there’s no need to blow yourself up in one shot.
