Bitcoin hourly closing prices --- contiguous block sampled from ~70K hourly bars (Bitstamp BTC/USD, 2018-2026)
Standard analysis sees: smooth / autocorrelated; long-range memory (persistent); time-irreversible (slow rise, sharp collapse); volatility-clustering (bursty); low-dimensional; nonstationary / drifting. The atlas additionally detects Nonstationarity:adf_pvalue. It sits beside ETH/BTC Ratio in the atlas (standard-bank rank 33) — a neighbor conventional features miss.
