For investors, it means that if you're still using the indicators that worked in 2021, you're looking at a map of a world that no longer exists.
From the abstract
We document a structural break in the predictive relationship between Bitcoin on-chain metrics and price following the approval of spot Bitcoin exchange-traded funds in January 2024. Using a systematic regime-comparative framework across three distinct market periods-pre-2022 (R1), the Luna-FTX contraction period 2022-2024 (R2), and the post-ETF period from January 2024 (R3)-we test 47 commonly used on-chain and market-derived metrics for forward price predictiveness. We find that 89.4% of metri
