The post How Coinbase’s 800,000 BTC migration exposes the flaw in raw Bitcoin age metrics appeared on BitcoinEthereumNews.com.

Some of Bitcoin’s most trusted bottom signals rest on the simple assumption that when old coins move, something meaningful has changed. Traders and analysts often interpret that as renewed selling, fresh distribution, or signs that the market hasn’t bottomed. That logic helped turn HODL Waves, Coin Days Destroyed, and long-term holder supply into some of the most widely used metrics in Bitcoin cycle analysis. The problem with that is that Bitcoin’s blockchain records movements and has no way of showing the motive behind them. On Nov. 22, 2025, Coinbase said it was transferring BTC and ETH from its legacy wallets to new internal wallets as part of a routine security practice. The company said the transfers were planned, internal, and unrelated to any breach or market event. But on-chain, it looked like a huge block of old coins suddenly waking up. If Coinbase hadn’t published the announcement beforehand, it would have taken some time before the movement stopped looking like pure selling pressure. At the time, CryptoSlate reported that the company moved nearly 800,000 BTC, representing roughly 4% of Bitcoin’s circulating supply and worth around $69.5 billion at the time. That’s large enough to overwhelm raw age-based readings and distort the story traders think the chart is telling. Why Bitcoin traders trust age-based signals so much HODL Waves are one of the most widely used metrics because they compress a wide range of holder behavior into a single view. Graph showing Bitcoin’s HODL waves from 2010 to 2026 (Source: Bitbo) It’s a macro snapshot of coin age across the total supply. As coins remain dormant, they mature into older age bands. So, when those same coins move, they leave those older bands and re-enter the youngest category. Analysts use that shift to judge whether long-term holders are still sitting tight…
