The Bearish Bat pattern is a bearish reversal pattern that forms in uptrends. It is characterized by a strong bullish move followed by a retracement that ends at the 38.2% Fibonacci retracement level. The second leg of the pattern then forms a bearish move that is equal in length to the first leg, creating the shape of a "bat." In Ethereum, this pattern would suggest that the price of Ethereum is likely to decrease in the future.
