This guide breaks down essential vocabulary, real-world applications, and the latest developments in the virtual currency space—perfect for improving your business English while staying informed on cutting-edge financial innovation.
What Are Cryptocurrencies and Virtual Currencies?
The growing popularity of cryptocurrencies has reignited interest in digital forms of money worldwide. As reported by CNBC, "Rising interest in cryptocurrencies has reignited central banks’ digital currency ambitions."
But what do these terms actually mean?
Currency comes from the Latin root “cur-” or “curr-”, meaning "to run" or "flow." Just like a current flows in water, money is designed to circulate.
- Related words: current (present), cursor (the moving pointer on a screen), concur (occur at the same time).
The prefix crypto- means “hidden” or “secret,” often associated with encryption. Hence, cryptocurrency literally means “encrypted currency.”
- Example: The museum curator left a cryptic message before vanishing. Here, cryptic means mysterious—just like how blockchain hides data through complex coding.
Virtual, meanwhile, refers to something that exists digitally rather than physically.
- Think of VR (virtual reality) or Meta’s focus on the metaverse—a fully digital world.
Note: In TOEIC and business contexts, virtual can also mean “almost” or “nearly.”
- Example: After losing millions in the stock market, Mr. Smith is virtually broke.

Mining, Miners, and the Environmental Debate
One of the most discussed aspects of Bitcoin is mining—the process by which new coins are created and transactions verified. This requires powerful computers solving complex mathematical problems, a task that demands massive amounts of electricity.
Key terms:
- Mining: The computational process of validating blockchain transactions.
- Miners: Individuals or groups who operate mining hardware.
- Mines: Locations where large-scale mining operations take place.
Countries like China once dominated global mining due to cheap energy sources. Regions such as Sichuan, Inner Mongolia, and Xinjiang hosted vast mining farms. According to the Cambridge Center for Alternative Finance (CCAF), around 50% of global Bitcoin mining occurred in China before 2021.
However, due to concerns over environmental impact and excessive power consumption, the Chinese government banned cryptocurrency mining. This led to a mass exodus of miners selling equipment and relocating operations overseas.
"The price of Bitcoin plummeted after China announced a ban on cryptocurrency mining."
This event not only affected market prices but also reshaped the geographical distribution of mining power, shifting it toward countries like the U.S., Russia, and Kazakhstan.
Hot Wallets vs. Cold Wallets: Security in Digital Transactions
When dealing with virtual currencies, security is paramount. Unlike traditional money, cryptocurrencies aren’t stored in physical form. Instead, ownership is proven through cryptographic keys recorded on the blockchain.
Two main types of storage exist:
🔹 Hot Wallets (Online Storage)
- Connected to the internet.
- Allows instant access for receiving, sending, or trading funds.
- Common examples: mobile wallets, web-based exchange accounts.
- Convenient but vulnerable to hacking.
🔹 Cold Wallets (Offline Storage)
- Typically USB-like devices disconnected from the internet.
- Much more secure against cyberattacks.
- Ideal for long-term holding of large amounts.
Both types fall under broader categories like digital wallet or mobile wallet. Since the pandemic, contactless payment methods—including digital wallets—have seen explosive growth due to hygiene concerns and convenience.

Real-World Adoption: From Tesla to National Policy
Elon Musk, CEO of Tesla, has been one of the most influential figures in the crypto space. In early 2021, Tesla made headlines by announcing it would accept Bitcoin as payment for its vehicles—a move that briefly boosted Bitcoin’s value.
However, Musk later reversed the decision, citing environmental concerns over fossil fuel usage in mining. Despite this reversal, his statements continue to influence market sentiment dramatically.
Other major players are also entering the field:
- Tim Cook, Apple CEO, revealed he owns cryptocurrency.
- Nike filed trademarks for virtual sneakers and apparel, signaling expansion into the digital goods market.
- El Salvador became the first country to adopt Bitcoin as legal tender in September 2023—a bold experiment being watched globally.
These developments highlight how deeply cryptocurrency is integrating into mainstream commerce and investment.
