Belle @0xGummyBear mentioned this 'Coinbase Premium Index,' which is also one of the indicators I frequently keep an eye on. Together with the Binance USDC/USDT exchange rate and RMMPC on Glassnode, they can be called the 'Three Core Indicators for Observing Dollar Purchasing Power.' Plus, the first two are free to access. 1. A negative Coinbase premium indicates a decline in buying enthusiasm among U.S. investors. 2. A Binance USDC/USDT exchange rate greater than 1 suggests more USDT is being sold for USDC, signaling an intention to exit the market. 3. In RMMPC, if the blue line falls below the red line, it shows that the driving force for BTC during U.S. trading hours is starting to weaken. If all three conditions are met, there's a high probability that BTC will lose its upward momentum. Currently, 1 and 2 have shown signs, but 3 hasn’t yet.
