Coin Metrics Revised 19 Months of Bitcoin ETF Wallet Data Without Disclosing Changes

WHY IT MATTERS

Think of crypto data providers like the scorekeepers at a sports game. If the scorekeeper quietly changes the scores from the last 19 months of games without telling anyone what was wrong or how much changed, it would be hard to trust the record. Coin Metrics provides data that many people use to understand how much Bitcoin is held by ETFs — investment products that let people invest in Bitcoin through traditional stock markets. When that data is revised without clear explanation, it makes it harder for everyone, from beginners to professionals, to know whether the information they relied on was accurate. This story is a reminder that in crypto, the companies providing data are not always required to be transparent about mistakes, so it is worth understanding where your information comes from.
