Editorial Principles
Concrete steps instead of vague safety advice
Actionable First
Every step is something the reader can actually follow and execute. No vague phrasing like 'roughly the process' or 'generally speaking'.
Real Error Reference
Lists the actual error messages we have encountered along with their fixes, instead of generic advice like 'please check your network'.
Continuous Maintenance
Exchange app versions, KYC flows, and API permissions change often. Every article carries a "last updated" date at the top so outdated content can be replaced.
How to spot phishing sites of crypto exchanges
Phishing sites pop up every day. A few generally applicable signals
- Always reach the exchange through a bookmarked URL or via search engine results — never click links from email, IM, or social media
- Inspect the HTTPS certificate: click the lock icon in the address bar; the issued-to field should match the exchange's registered company or one of its affiliated entities
- Common look-alike tricks:
missing a letter,added prefix or suffix,Cyrillic letter substitution— visually almost identical - Official email subjects always contain the anti-phishing code you set up. Emails without it should be treated as phishing without exception
- Legitimate exchange support never reaches out first through Telegram, QQ, or WeChat, and never asks for your password, 2FA code, or seed phrase
A few terms newcomers keep searching for
High-frequency terms from exchange docs, translated into one-line plain English
KYC
Short for Know Your Customer — the process where the exchange asks you to upload an ID and pass a liveness check. A compliance requirement
Spot vs Futures
Spot means you buy and hold the actual coin. Futures use margin and leverage (up to 125x), so both gains and losses are amplified
P2P
Peer-to-Peer — users trade local currency (CNY, IDR, etc.) directly for USDT with each other; the platform only escrows the trade
Cold wallet reserve
Some major exchanges set aside a portion of trading fee revenue as an offline cold reserve, used to reimburse users in incident scenarios. Exact percentages and trigger conditions vary by exchange
Frequently Asked Questions
A cryptocurrency exchange is a platform that matches buyers and sellers of digital assets such as Bitcoin and Ethereum, primarily offering spot trading, derivatives, and Web3 wallet services. Major global exchanges differ in regional licensing, asset coverage, fees, and derivative products.
KYC stands for Know Your Customer — the process of uploading an ID and completing a liveness check. Regulators in most jurisdictions require exchanges to verify users before enabling deposits, withdrawals, or large trades. The flow usually takes 5-30 minutes.
Spot trading means buying and holding the actual coin. Futures use margin and leverage (often up to 100x or more), so both gains and losses are amplified, and forced liquidation can wipe out the entire margin. Beginners should start with spot and only consider futures after understanding the mechanics.
P2P (Peer-to-Peer) lets users trade local currency for stablecoins like USDT directly with each other, with the exchange acting as escrow. It is a common entry path in regions where fiat rails are unavailable. Pick high-reputation merchants, follow exact payment-memo rules, and avoid bank-side risk control.
Three things to do first: (1) bind a TOTP-based 2FA (Google Authenticator or similar) and avoid relying on SMS only; (2) set an anti-phishing code so every official email carries a custom string in its subject; (3) configure a withdrawal whitelist so unauthorized addresses cannot pull funds.
Stablecoins are cryptocurrencies pegged 1:1 to fiat currency (usually USD). Common ones include USDT, USDC, and DAI. Inside the crypto market they act as a "dollar equivalent," and most trading pairs are quoted against USDT. The coin price itself is stable, but issuer credit risk should still be considered.
