Bitcoin (CRYPTO: BTC) has dropped roughly $10,000 in recent weeks, falling from around $83,000 to near $73,000 after rejecting almost exactly at its 200-day moving average.Why BTC Looks VulnerableCrypto analyst Benjamin Cowen said on May 29 this rejection mirrors similar bear market setups in 2018 and 2022, when Bitcoin rallied into the 200-DMA before rolling over again.Cowen said Bitcoin remains inside its historical midterm-year "window of weakness," a period that has often pressured the asset during prior four-year cycles.He noted that Bitcoin has typically formed lows during the first half of midterm years:

First major drop near the end of the post-halving year

February low

March or April higher low

Another weakness window into June
