$BTC $BTC 4.18 Bitcoin Market Analysis: The WXYXZ wave structure anticipated for Bitcoin on March 27 has largely materialized, with the key Z-wave rally exhibiting a clear three-wave zigzag pattern. The upward move initiated near $65,000 has completed three zigzag impulses and is currently nearing the end of the third zigzag, potentially culminating in a final fifth-wave surge or having already completed outright. Given that the Z-wave structure is nearing completion, trading strategy should shift from earlier long positions at lower levels to short positions at higher levels. It is recommended to gradually establish short positions in the range of $77,000 to the upper channel boundary, approximately a 4% zone. The first target is the lower boundary of the recent uptrend channel; once broken, subsequent targets are the lower boundaries of larger channels and the $67,000–$68,000 region. Ethereum’s price action remains highly synchronized with Bitcoin, and its Z-wave has also formed a three-wave zigzag structure nearing completion. The shorting range can be referenced around the upper channel boundary near $2,550, within a ~5% volatility range, using a gradual position-building strategy, with the first target also set at the lower channel support. Note that the final fifth wave may develop into a failed wave; therefore, avoid chasing prices during the last minor upward push. All trades must strictly manage position size and leverage. Market structure evolution requires continuous monitoring—always prioritize risk management.
