Crypto moves fast and we get things wrong too — sometimes we state something imprecisely, sometimes we mix up a number, and sometimes something that was right at the time later goes out of date. Making a mistake isn't the scary part; pretending you didn't is.
So whenever we change something factual, we log it here: when we changed it, which page, what it used to say, what it says now, and why. You can check it, and you can hold us to it. This page only grows.
How to read this page
Entries below are in reverse chronological order (newest first). "Before" is how it read previously; "After" is how it reads now. We don't log typos or layout tweaks that don't affect meaning — this page only collects substantive corrections that could affect your judgment.
2026-05-27 ｜ The USDC depeg date and depth were too vague
Page affected: Are stablecoins really "stable"?
| Before | "USDC briefly lost its peg a few years ago and dipped below $1 at one point." |
| After | "During the collapse of Silicon Valley Bank (SVB) in March 2023, USDC had about $3.3 billion of reserves held at that bank, which spooked the market; the price fell to roughly $0.87 and returned to around $1 within a few days as the situation settled." |
| Reason | "A few years ago" and "dipped below" are no use to a beginner. How far it actually fell, how long it lasted and why is exactly what tells you whether a stablecoin is really stable. Adding the specific date (March 2023), the cause (a reserve bank failing) and the depth (about $0.87) is what makes the example actually instructive. |
2026-05-21 ｜ "TRC20 and ERC20 addresses are interchangeable" was misleading for beginners
Page affected: 12 traps beginners fall into in their first year
| Before | "The same coin has roughly similar addresses across chains — just pick the right one when you transfer." |
| After | "The address formats may look similar, but they are not interchangeable. Withdrawing on the TRC20 network to an address that only supports ERC20 will very likely lose the assets permanently." |
| Reason | A reader told us that "roughly similar" and "just pick the right one" made them think the worst case was a slow arrival. In reality, sending across the wrong network is an irreversible loss of coins, which is far more serious. We separated "looks alike" from "actually not interchangeable" and added a blunt warning about the consequence. This is one of the most common ways beginners lose money, so the wording has to be unambiguous. |
2026-05-15 ｜ The fees section didn't distinguish maker from taker
Page affected: Understanding fees: who's taking your money
| Before | "Spot trading fees are generally about 0.1% of the trade value." |
| After | "Spot fees come in two kinds: a maker — your limit order rests on the book waiting for someone to fill it, usually at a lower or even zero fee; and a taker — you immediately fill an existing order on the book, usually at a slightly higher fee. The exact rate depends on the exchange's published tier at the time." |
| Reason | The original gave one blanket number, which was both inaccurate and missed the key way beginners save money: a resting limit (maker) order is often cheaper than a market (taker) order. Explaining the maker/taker difference lets readers see that how you place an order directly affects the fee. We also removed the hard-coded "0.1%" and pointed to the exchange's live rates, so an outdated figure doesn't keep misleading people. |
2026-05-09 ｜ Candlestick "red up / green down" didn't note the regional difference
Page affected: What is a candlestick? Chart-reading lesson one
| Before | "On a candlestick chart, red means up and green means down." |
| After | "Color meaning differs by regional convention: in Western markets, green is up and red is down by default; in mainland China and many Chinese-language exchanges, red is up and green is down. Many platforms also let you switch this in settings. So don't go by color alone — always read direction from the candle's open/close prices." |
| Reason | The original assumed one regional convention, which could make readers read the direction backwards on a different platform. Adding the regional difference and the "read the price, not just the color" reminder makes it safer for everyone. |
2026-05-03 ｜ Changed "a cold wallet is absolutely safe" to something more accurate
Page affected: 6 ways a seed phrase gets stolen
| Before | "Put your coins in a cold wallet and they're absolutely safe — it's offline, so hackers can't reach them." |
| After | "A cold wallet (keeping the private key offline) blocks the vast majority of online theft, but it isn't foolproof: if the physical backup of your seed phrase is seen, photographed or stolen, you can still lose the coins; and at the moment you sign a transaction, approving a malicious contract can drain your assets just the same. What's safe is keeping the private key offline — not the device itself." |
| Reason | "Absolutely safe" is one of our own red-line phrases that shouldn't have appeared. A cold wallet reduces the risk of online theft, but human leaks of the seed phrase and bad approvals still exist. Cutting "absolutely" and stating the risks fully keeps readers from a false sense of security. |
