Cryptocurrency analyst Rekt Capital predicts a market shift as Bitcoin approaches its fourth halving event on April 19. The analyst outlines three phases: the final pre-halving retrace, re-accumulation, and a parabolic uptrend. Bitcoin has recently pulled back by 18%, similar to past pre-halving retraces. The halving event, which reduces the reward for mining new blocks, historically impacts Bitcoin's price significantly. Other traders also anticipate positive outcomes from the halving.
