Warnings over a potential pullback abound, while others are already commiserating bears ahead of time.“Now bears will be caught in the vicious cycle of praying for pullbacks to go lower, not realizing the tides have shifted for a time and we’re going higher,” Chris Burniske, former head of crypto at ARK Invest, summarized.Even more optimistic takes such as that of Burniske, however, do not foresee the upside continuing uninterrupted in a definitive end to Bitcoin’s latest bear market.Uploading the classic “Wall Street Cheat Sheet” graphic over the weekend, popular commentator Lemon predicted that BTC/USD would still fall further.“Sorry, I have to be true to my thoughts, I think we are here,” he told Twitter followers, pointing to Bitcoin sentiment — and price — heading toward macro lows.“Wall Street Cheat Sheet” annotated chart.
