What Is “Cryptocurrency” in English?
When discussing digital money in English, the most accurate and widely accepted term is cryptocurrency.
You might be tempted to translate “仮想通貨” literally as virtual currency, but while that phrase exists in English, it's not the standard term used in financial or technological contexts. Instead, cryptocurrency is the go-to word globally.
The term combines two parts:
- Crypto — short for "cryptography," referring to the secure encryption methods that protect transactions.
- Currency — meaning "money" or "medium of exchange."
Together, they form cryptocurrency, which technically means “encrypted digital money.” This reflects both its technological foundation and economic function.
It’s important to note that “virtual currency” can sometimes refer to game currencies (like in online RPGs) or private digital tokens not based on blockchain. So using cryptocurrency ensures clarity and precision.
Example Sentences Using "Cryptocurrency"
Here are some natural ways to use the word in conversation:
- Cryptocurrencies have been in trouble recently due to the FTX incident.
→ Highlights market volatility and real-world events affecting digital assets. - Bitcoin is the cryptocurrency with the highest market capitalization.
→ Emphasizes Bitcoin’s dominance in the crypto space. - The prices of cryptocurrencies are volatile.
→ A common observation about their price fluctuations.
These examples show how cryptocurrency fits naturally into discussions about finance, investment, and technology.

How to Say “Crypto Assets” in English
Another commonly used term in Japan is 暗号資産 (angou shisan) — officially adopted by Japanese regulators to emphasize the asset nature of digital tokens rather than treating them purely as currency.
In English, this translates directly to crypto assets.
This phrase is increasingly popular among institutions, regulators, and investors because it frames digital tokens as investment vehicles — similar to stocks, bonds, or commodities — rather than just payment methods.
Like “cryptocurrency,” it’s a compound noun:
- Crypto = encryption-based technology
- Assets = valuable resources owned by individuals or organizations
Since most people hold crypto for investment purposes (rather than daily spending), “crypto assets” often feels more accurate than “cryptocurrency.”
Example Sentences Using "Crypto Assets"
- Crypto assets are untouchable assets.
→ Refers to their digital-only nature; you can’t physically hold them. - Crypto assets are constantly fluctuating in price.
→ Describes their high market volatility. - I lost all my crypto assets in just one day.
→ A cautionary tale about risk management in trading.
Using “crypto assets” adds nuance and professionalism, especially when discussing portfolios, taxation, or regulatory compliance.
The Origin of Cryptocurrency
To truly understand cryptocurrency, it helps to know where it all began.
Satoshi Nakamoto: The Mysterious Founder
The story starts in October 2008, when an individual or group using the name Satoshi Nakamoto published a groundbreaking paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System."
This whitepaper introduced a revolutionary idea: a decentralized digital currency that operates without banks or central authorities. It solved the long-standing problem of double-spending in digital transactions using cryptographic proof and a distributed ledger — what we now call blockchain technology.
In January 2009, Nakamoto launched the Bitcoin network by mining the first block (known as the genesis block). Just over a year later, the first cryptocurrency exchange was established, allowing people to trade Bitcoin for fiat money.
Despite intense speculation, Satoshi Nakamoto’s true identity remains unknown. The name appears Japanese, but there’s no conclusive evidence about nationality or whether it refers to one person or a team.
What’s clear is that this anonymous innovator laid the foundation for an entire industry.
Bitcoin: The First Cryptocurrency
Bitcoin (BTC) is widely recognized as the first successful cryptocurrency. It remains the most valuable by market capitalization and is often referred to as “digital gold” due to its limited supply (capped at 21 million coins) and store-of-value properties.
Bitcoin isn't just a currency — it's a protocol, a network, and a movement toward financial decentralization. You can buy Bitcoin on major exchanges worldwide, including platforms based in Japan like DMM Bitcoin and GMO Coin.
Remember: Always do your own research (DYOR) before investing in any digital asset.
Ethereum: The Second-Largest Crypto
While Bitcoin started the revolution, Ethereum (ETH) expanded its possibilities.
Launched in 2015 by Vitalik Buterin and others, Ethereum introduced smart contracts — self-executing agreements written in code. This innovation enabled decentralized applications (dApps), non-fungible tokens (NFTs), and decentralized finance (DeFi).
As of now, Ethereum holds the second-largest market cap after Bitcoin. Its native token, Ether (ETH), powers transactions and computations on the network.
Ethereum gained further attention in late 2022 with The Merge, a major upgrade that shifted the network from energy-intensive proof-of-work to eco-friendly proof-of-stake consensus.
Essential Cryptocurrency-Related Terms in English
To communicate effectively about crypto, here are three foundational terms you should know:
Wallet
A wallet is a digital tool that allows users to store, send, and receive cryptocurrencies. Think of it as your personal bank account interface — except you control the keys.
There are different types:
- Hot wallets (connected to the internet — e.g., MetaMask)
- Cold wallets (offline hardware devices — e.g., Ledger)
Popular wallets like MetaMask or Fantom Wallet let you interact with blockchains, manage multiple tokens, and connect to dApps.
Blockchain
Blockchain is the underlying technology behind all major cryptocurrencies.
Imagine a digital spreadsheet duplicated across thousands of computers. Every time a new transaction occurs, it’s verified and added as a new “block” linked to previous ones — forming a secure chain.
Key features:
- Decentralized (no single point of control)
- Transparent (anyone can view transactions)
- Tamper-resistant (nearly impossible to alter past data)
Because blockchain eliminates intermediaries like banks, it’s praised for increasing efficiency and trust in financial systems.
Trade
To trade means to buy or sell cryptocurrencies, usually on an exchange platform.
For example:
- "I plan to trade Bitcoin for Ethereum."
- "She makes daily trades based on technical analysis."
The word trade is also used in stock and forex markets, so mastering it gives you broader financial literacy.
Frequently Asked Questions (FAQ)
Q: Is 'virtual currency' wrong in English?
A: Not entirely wrong, but cryptocurrency is more accurate and widely used. “Virtual currency” may refer to non-blockchain digital tokens (like in games), so it lacks specificity.
Q: Should I say 'cryptocurrency' or 'crypto assets'?
A: Use cryptocurrency when focusing on money or payments. Use crypto assets when discussing investments, portfolios, or regulatory topics — it emphasizes value over utility.
Q: Who owns Bitcoin?
A: No single entity owns Bitcoin. It’s maintained by a global network of computers (nodes) following open-source rules. Ownership of coins depends on private keys held by individuals.
Q: Can I use 'Bitcoin' and 'cryptocurrency' interchangeably?
A: No. Bitcoin is one type of cryptocurrency, like how Toyota is one brand of car. There are thousands of other cryptos (e.g., Ethereum, Solana).
Q: Why is blockchain important?
A: Blockchain ensures security, transparency, and decentralization. It removes reliance on central authorities and reduces fraud risk — crucial for trustless financial systems.
Q: Do I need a wallet to invest in crypto?
A: Yes. Even if you buy crypto through an exchange app, your funds are stored in a wallet (either managed by you or the platform). For full control, use a self-custody wallet.
