What Is a Cryptocurrency Exchange? A Beginner's Guide
A cryptocurrency exchange is an online platform where users can buy, sell, or trade digital currencies such as Bitcoin (BTC), Ethereum (ETH), and thousands of altcoins.
Unlike traditional financial systems, cryptocurrencies operate on decentralized networks using blockchain technology—meaning no central authority like a bank controls them. Transactions are recorded on a public ledger secured by cryptography.
Key Features of Cryptocurrencies
- Low transaction fees compared to banks or remittance services
- Available 24/7, enabling trading anytime
- Capped supply for most coins (e.g., Bitcoin has a max of 21 million)
- Immutable records prevent double-spending and counterfeiting
- Pseudonymous transactions protect user privacy
Types of Cryptocurrency Exchanges
There are two primary models used by exchanges:
- Exchange (Order Book Model): You trade directly with other users. Fees apply based on maker/taker roles.
- Sales Desk (Instant Buy/Sell): The exchange acts as the counterparty. Prices include a spread but often no direct fee.
Understanding these models helps you choose between speed and cost-efficiency depending on your trading style.

How to Choose the Right Cryptocurrency Exchange
Japan alone has over 29 Financial Services Agency (FSA)-registered crypto exchanges, not counting international platforms. With so many options, it’s essential to evaluate exchanges using clear criteria.
Here are three core factors to consider:
Supported Cryptocurrencies
Not all exchanges list the same coins. While major ones like BTC and ETH are widely available, niche or newly launched tokens may only appear on select platforms.
For example:
- Binance supports over 300 cryptocurrencies
- Some Japanese exchanges offer fewer than 10
If you're interested in altcoins or emerging projects, prioritize platforms with broader listings.
Fee Structure
Exchanges charge various types of fees:
- Trading fees (spot/margin/futures)
- Spread costs on instant purchases
- Funding fees for leveraged positions
- Deposit and withdrawal fees in fiat or crypto
Even small differences compound over time. For active traders, low-fee platforms like GMO Coin or SBI VC Trade offer significant savings.
User Experience & Tools
A clean interface matters—especially during fast-moving markets.
Look for:
- Mobile app usability
- Charting tools and technical indicators
- Order types (limit, market, stop-loss)
- Customer support responsiveness
Beginners might prefer simple apps like LINE BITMAX, while pros may lean toward advanced dashboards like those on Binance or bitbank.

Q2: Are CFDs safe for crypto trading?
Crypto CFDs (Contracts for Difference), offered by platforms like Monex Bitcoin and Okasan Online, allow leveraged trading without owning actual coins. They reduce theft risk but carry high market risk due to volatility and leverage. Suitable for experienced traders only.

Q5: Do I need to pay taxes on crypto trades?
Yes. In Japan and most countries, cryptocurrency gains are taxable events. Always keep records of transactions for tax reporting.
