Bitcoin has created a financial legend over the past eight years—its price surged nearly 3 million times, peaking at over ¥20,000 in some markets. This phenomenon tells different stories to different audiences: speculators see profit opportunities, tech enthusiasts envision transformative technology, and traditional financial institutions perceive a disruptive force.
Today, we explore Bitcoin, Ethereum, and their underlying blockchain technology. Can they truly reshape the global economy? By the end of this article, you’ll form your own conclusion.
The Birth of Bitcoin: A Financial Revolution?
Electronic payment systems like Alipay and WeChat Pay dominate today’s landscape. Yet, two core challenges define the ambitions of this industry:
- Enabling peer-to-peer online transfers without centralized third parties.
- Securing transaction records to prevent double-spending and ensure fund safety.
Solving these would create an independent digital currency system, bypassing traditional banking.
In 2008, an entity under the pseudonym Satoshi Nakamoto published a whitepaper titled "A Peer-to-Peer Electronic Cash System", proposing:
- A decentralized digital currency with intrinsic value.
- A distributed ledger (blockchain) to record and share transactions globally.
By 2009, Bitcoin launched as the first application of blockchain technology, proving its potential beyond currency.
Key Highlights of Bitcoin
(1) Outperforming Amazon
Bitcoin’s value skyrocketed from $0.0008 (2009)** to **$2,300+ (2017), a 290-million-fold increase. A $100 Bitcoin investment in 2010 would now exceed **$73 million**, compared to Amazon’s $64,000 ROI over 20 years. However, Bitcoin’s volatility makes it a high-risk asset.
(2) How Bitcoin Is Created: Mining
Like gold mining, Bitcoin is "extracted" through computational processes. Miners use specialized hardware to solve algorithms, earning Bitcoin as rewards.
(3) Real-World Use Cases
- Traded on exchanges like stocks.
- Accepted as payment (e.g., Japan recognizes it as legal tender).
- Over 370 billion USD in market capitalization.
Ethereum: Bitcoin’s Competitor
In 2013, 19-year-old Vitalik Buterin introduced Ethereum via a whitepaper. By 2015, its platform went live, raising $150 million and enabling smart contracts—self-executing agreements without intermediaries (e.g., lawyers).
Ethereum’s Dual Currency System
- Ether (ETH): Pays for transaction fees on the network.
- Ethereum Classic (ETC): Emerged after a $50M hack in 2016.
