What this log is for.
The corrections page records material changes to CoinView pages: factual fixes, broken links, stale source references, affiliate disclosure edits, risk-language clarifications and data-method changes. Minor grammar edits are usually not logged unless they change meaning.
How a correction is reviewed.
A reader can send the affected URL, a short description, the suspected error and a source to [email protected]. CoinView checks whether the point is factual, current, material to risk, and reproducible from public information.
What gets published.
Accepted corrections should identify the date, affected page, old issue, new wording or method, and why the change matters. When the error affects a calculator or data table, the change should mention the formula or source that changed.
Local examples.
For English-language pages, relevant correction sources can include SEC investor alerts, CFTC derivatives materials, FTC endorsement guidance, ETF issuer pages, Glassnode methodology notes, Coinglass data screens and exchange API documents.
What does not count.
A disagreement with an editorial interpretation is not automatically an error. CoinView may add context when a critique is useful, but a correction log is reserved for changes that improve factual accuracy, disclosure or reader safety.

2026-09-26 · Data readings corrected or removed against public sources
Scope: data readings across the Chinese and English sites, plus some Hebrew, Swahili and Thai pages.
Problem: Across the Chinese and English pages, a number of readings did not match what public data actually shows, or had no source a reader could check. Most of them sat in a few areas: halving cycles and on-chain metrics, stablecoins and Bitcoin dominance, the Coinbase premium, the weekly ETF flow report, volatility and the perp/spot volume ratio, and the RSI and MACD case studies. Metrics from paid on-chain data platforms (MVRV, SOPR, exchange balances and similar) had been quoted as exact historical values that readers had no way to verify. The perp/spot ratio dashboard coloured readings against fixed tiers (anything above 5x counted as overheated), yet BTC's daily ratio has had a median of about 8.4x since 2024, so the dashboard showed "overheated" almost every day. When its data feed failed, the volatility dashboard fell back to a placeholder set of 38 / 40 / 42 labelled as the May 2026 norm, while BTC's actual 30-day volatility in May 2026 ran at roughly 25% to 37%.
Fix: From 2026-09-26, the affected readings were recalculated or checked one by one against Binance public klines, Binance futures funding rates and long/short ratios, alternative.me, DefiLlama, Coinbase public candles and Farside Investors. Readings that did not hold up were corrected or removed. Exact historical values of paid on-chain metrics were removed and replaced with an explanation of how to read each metric. In particular: the perp/spot ratio dashboard now colours each coin against the P20 / P50 / P80 of its own daily ratio from 2024-01-01 to 2026-09-25 (7.0x / 8.4x / 9.8x for BTC), states the method and date range on the page, and notes that data from July 2022 to March 2023, when Binance charged no fees on BTC spot pairs, is not comparable. The volatility dashboard's placeholder values were replaced with a dated offline snapshot from 2026-09-25 (7-day 48.4%, 30-day 42.3%, 90-day 38.8%, computed with the same method as the live readings), and the formula described in the text now matches the one the dashboard uses (daily log returns minus their mean, divided by N). The May 2026 ETF weekly report, and pages that cite it, now follow Farside's figures: net outflows of about $2.0 billion over the six trading days from 12 to 19 May, led by IBIT. The start date of 24/7 trading for CME crypto futures is now given as 29 May 2026, citing the CME Group press release. In the same pass, the ratio tiers, the August 2024 volatility and funding-rate readings on the Hebrew, Swahili and Thai pages, and the May flow figures in the Thai ETF weekly report were corrected.
