Bitcoin has evolved from a niche digital experiment into one of the most influential financial assets of the 21st century. In May 2025, it made headlines by surpassing $110,000, marking a historic milestone and solidifying its position as the fifth-largest asset globally. Once dismissed by mainstream finance, Bitcoin is now embraced by institutions and governments alike. But what exactly is Bitcoin? How does it work? And how can you start investing in it—especially from Hong Kong? This comprehensive guide breaks down everything you need to know about Bitcoin, from its core principles to current market trends and practical investment strategies.
What Is Bitcoin?
Bitcoin is a decentralized digital currency created in 2009 by an anonymous figure known as Satoshi Nakamoto. As the first cryptocurrency built on blockchain technology, it operates independently of central banks or government oversight. Its design combines cryptographic security with economic scarcity, making it a unique asset in today’s financial landscape.
Key characteristics that define Bitcoin include:
- Decentralization: Transactions occur directly between users (peer-to-peer) without intermediaries like banks.
- Fixed Supply: Only 21 million Bitcoins will ever exist, creating a deflationary model similar to "digital gold."
- Transparency and Security: All transactions are recorded on a public ledger (blockchain), secured through advanced cryptography.
- Global Accessibility: Bitcoin can be transferred across borders instantly, offering financial inclusion beyond traditional systems.
These features have contributed to Bitcoin’s growing acceptance as both a store of value and a medium for investment.
Bitcoin Price and Market Performance
As of mid-2025, Bitcoin reached an all-time high above $110,000, reflecting strong institutional adoption and macroeconomic trends favoring hard assets. Analysts attribute this surge to several factors, including increased demand for non-sovereign stores of value amid global monetary uncertainty.

Technical analysis suggests that after peaking at $109,640 in January 2025, Bitcoin underwent a healthy correction, dipping to around $74,508 before forming a "round bottom" reversal pattern. This bullish formation indicates potential for further upside, with mid-term price targets estimated near $144,000.
Market experts highlight that the current environment reflects a classic "strong uptrend with minimal pullbacks," emphasizing the importance of strategic entry points rather than timing the market perfectly.
How to Invest in Bitcoin
There are multiple ways to gain exposure to Bitcoin, depending on your risk tolerance, capital, and investment goals.
1. Direct Purchase (Spot Trading)
Buying Bitcoin outright allows full ownership and direct participation in price movements. Platforms regulated in Hong Kong now enable users to purchase BTC using HKD or USD without converting to stablecoins like USDT. With low minimum investments—some starting at just HK$80 or USD $10—entry barriers have significantly decreased.
However, spot trading involves volatility risk. Prices fluctuate 24/7, so investors must be prepared for rapid swings.
2. Bitcoin ETFs
For those seeking easier access, Bitcoin exchange-traded funds (ETFs) offer a simpler alternative. These products track Bitcoin’s price without requiring direct custody of the asset.
Hong Kong Bitcoin ETFs
Locally listed spot ETFs allow investors to buy shares through standard brokerage accounts. As of May 2025, entry prices start as low as HK$861.5 per unit—making them highly accessible compared to purchasing whole Bitcoins.

U.S. Spot Bitcoin ETFs
Approved by the SEC in early 2024, these ETFs hold actual Bitcoin in regulated custody. They provide long-term investors with transparent exposure while avoiding the complexities of self-storage.
U.S. Futures-Based ETFs
These funds track Bitcoin futures contracts traded on exchanges like CME. Due to rollover costs and leverage effects, they may deviate from spot prices over time and are typically suited for professional investors.
3. Related Investment Vehicles
Investors can also consider:
- Blockchain companies developing infrastructure.
- Mining firms involved in Bitcoin production.
- Financial tech stocks integrating crypto services.
While these options offer indirect exposure, their performance depends on both market sentiment and company-specific fundamentals.
4. Derivatives (For Experienced Traders)
Advanced instruments such as futures, options, and ETF-linked derivatives allow leveraged trading and hedging strategies. However, these carry higher risks and are generally restricted to professional investors.
Frequently Asked Questions
Q: Can I buy fractional amounts of Bitcoin?
A: Yes. Most platforms allow purchases of fractions down to 0.00000001 BTC (one satoshi), enabling affordable entry regardless of price.
Q: Is Bitcoin legal in Hong Kong?
A: Yes. Hong Kong regulates virtual assets under a licensing framework. Licensed platforms can offer crypto trading services to retail and institutional clients.
Q: What’s the difference between spot and futures ETFs?
A: Spot ETFs hold real Bitcoin and closely mirror its price. Futures ETFs use derivatives contracts, which may lead to tracking errors due to expiration cycles and roll costs.
Q: Are there fees when buying Bitcoin?
A: Many platforms now offer zero-commission trading for major cryptocurrencies like BTC and ETH, though deposit or withdrawal fees may apply.
Q: How do I store Bitcoin safely?
A: Use secure wallets—either hardware devices (cold storage) or trusted exchange platforms with insurance and multi-signature protection.
Q: When is the best time to invest in Bitcoin?
A: There’s no perfect timing. Dollar-cost averaging (DCA)—investing fixed amounts regularly—helps reduce volatility impact over time.
