On-chain analytics platform focused on Bitcoin and Ethereum with institutional-grade metrics. HODL waves, SOPR, NUPL, exchange inflows/outflows and hundreds of other indicators that help understand what's happening under the hood of the market. The go-to for serious macro on-chain analysis. Free tier gives you basic metrics with a delay, paid plans unlock real-time data and advanced charts. If you're trying to understand where BTC is in its cycle, GlassNode probably has a chart for that.
