The world of digital finance is evolving at an unprecedented pace, with blockchain technology at the heart of this transformation. In the first half of 2025, U.S. patent applications related to blockchain, cryptocurrency, Bitcoin, and Ethereum nearly doubled compared to the same period last year, signaling growing institutional interest and technological innovation. This surge aligns with the dramatic price movements and market expansions seen in leading cryptocurrencies—especially Bitcoin and Ethereum.
While blockchain's potential spans industries from supply chain to healthcare, its most tangible impact so far has been in financial technology. However, as adoption accelerates, regulatory bodies are being forced to respond—raising questions about the future balance between innovation and oversight.

Bitcoin: Soaring Value and the Birth of Bitcoin Cash
Bitcoin, the pioneer of decentralized digital currency, has seen its value climb to new heights. Once dismissed as a niche experiment, a single Bitcoin now trades at approximately $3,000—equivalent to over 100,000 New Taiwan Dollars. This resurgence has been fueled by macroeconomic factors such as dollar depreciation and increased investor appetite for alternative assets.
Designed with a capped supply of 21 million coins, Bitcoin operates without a central issuing authority. Instead, new coins are generated through a process known as "mining," where users solve complex mathematical problems to validate transactions and secure the network. Much like gold, Bitcoin functions both as a medium of exchange and a store of value—making it particularly attractive during times of economic uncertainty.
However, Bitcoin’s rising popularity has exposed limitations in its original design. Each block in the Bitcoin network is limited in size, restricting the number of transactions it can process per second. As transaction volume grows, this bottleneck slows confirmation times and increases fees—frustrating miners and users alike.
In response, a faction of developers and miners initiated a hard fork on August 1, 2025, creating a new cryptocurrency: Bitcoin Cash (BCC). By doubling the block size from 1MB to 2MB, Bitcoin Cash aims to improve transaction throughput and mining efficiency. Though not universally accepted by the Bitcoin community, BCC quickly gained traction. Within just ten days of launch, it emerged as the third-largest cryptocurrency by market capitalization—trailing only Bitcoin and Ethereum.
This split underscores a fundamental tension in decentralized networks: the struggle between maintaining consensus and adapting to changing demands. While purists argue that preserving Bitcoin’s original protocol ensures security and scarcity, others believe scalability must take precedence for mass adoption.
Ethereum: Smart Contracts Driving Market Expansion
While Bitcoin dominates headlines, Ethereum has quietly achieved something remarkable—explosive growth in both market value and real-world utility. Unlike Bitcoin, which primarily serves as digital money, Ethereum is a decentralized platform for executing smart contracts: self-executing agreements coded directly into the blockchain.
To use Ethereum’s network, participants must pay fees in its native cryptocurrency, Ether (ETH). Think of Ethereum as a vast digital playground where developers can build decentralized applications (dApps), from financial services to gaming platforms—all without relying on centralized intermediaries.
This flexibility has driven demand for Ether. At the beginning of 2025, Ether was trading below $10. By mid-year, it briefly approached $400 and now stabilizes around $250. More importantly, Ethereum’s total market capitalization has grown over 300% in the past six months—matching Bitcoin’s gains despite starting from a smaller base.
The reason? Ethereum powers the booming ecosystem of Initial Coin Offerings (ICOs), where startups raise funds by issuing their own tokens in exchange for Ether. This model mirrors traditional IPOs but operates globally and with fewer gatekeepers—enabling rapid innovation while raising regulatory concerns.
Why Smart Contracts Matter
Smart contracts eliminate the need for trust between parties. Once deployed on the blockchain, they execute automatically when predefined conditions are met. For example:
- A payment is released only after delivery confirmation.
- Insurance claims are processed instantly upon verification of an event.
- Digital assets are transferred upon receipt of funds.
Because these actions are transparent and immutable, they reduce fraud, lower costs, and increase efficiency across industries.

Regulatory Shifts: From Skepticism to Supervision
Governments once viewed cryptocurrencies with suspicion, often labeling them as tools for speculation or illicit activity. But attitudes are shifting.
In April 2025, Japan amended its Payment Services Act to formally recognize digital currencies as legal tender for transactions. Travelers to Japan may now use Bitcoin at major retailers like BIC CAMERA—a sign that crypto is entering mainstream commerce.
More significantly, the U.S. Securities and Exchange Commission (SEC) released a landmark report in July 2025, declaring that ICOs fall under federal securities regulations. This means projects raising capital through token sales must comply with disclosure requirements, much like companies conducting IPOs.
This move brings much-needed transparency to a space previously rife with unverified claims and opaque offerings. While some fear overregulation could stifle innovation, others welcome clearer rules that protect investors and legitimize the market.
The clash between decentralization—the core philosophy behind blockchain—and centralized regulatory oversight remains unresolved. Yet this tension is also driving progress, pushing developers to create compliant yet innovative solutions.
Frequently Asked Questions (FAQ)
Q: What caused Bitcoin’s price to rise in 2025?
A: A combination of macroeconomic factors—including dollar depreciation—and increased institutional interest contributed to Bitcoin’s price surge. Limited supply and growing recognition as a digital store of value also played key roles.
Q: How is Ethereum different from Bitcoin?
A: Bitcoin is primarily designed as digital money. Ethereum is a programmable blockchain that supports smart contracts and decentralized applications, making it more versatile for developers and enterprises.
Q: Is Bitcoin Cash widely accepted?
A: While not supported by all exchanges or wallets, Bitcoin Cash has gained significant market presence since its launch and is traded on major platforms.
Q: What are smart contracts?
A: Smart contracts are self-executing agreements written in code. They run on blockchains like Ethereum and automatically enforce terms when conditions are met—without intermediaries.
Q: Are ICOs legal?
A: Following the SEC’s 2025 guidance, ICOs that offer investment opportunities are subject to securities laws in the U.S., meaning they must register or qualify for exemptions.
Q: Can I use cryptocurrency for everyday purchases?
A: Yes—especially in countries like Japan, where retailers accept Bitcoin. Adoption is growing, though volatility remains a barrier to widespread daily use.
