Crypto analyst Doctor Profit has identified 15 indicators confirming Bitcoin's strong bear market. Key signals include a bearish divergence since summer, a confirmed death cross, and the loss of the EMA50W. Additionally, the analyst points to empty repo markets, low liquidity, and the repetition of the 2021-2022 bearish pattern. Other factors include weak bank liquidity and the Yen's downtrend against the USD. Doctor Profit asserts that Bitcoin remains in a major bear market cycle with no immediate signs of recovery.
