The recent crypto market cycle has been exceptionally challenging, characterized by rapid, unpredictable swings that have "cooked" even experienced traders like Z. Investors who feel they haven't "nailed it" this cycle are in good company, as the market has been described as "diabolical/nightmare difficulty" with instances of sharp rallies to new ATHs followed by immediate dumps. This suggests extreme volatility and the potential for continued unpredictable price action in the broader crypto market.
