Looking at Ethereum you can see a very noticeable bearish symmetric triangle, some people may get this mixed up with a pennant but the difference between the two is that with a bearish triangle, the price starts from the high point, whereas a pennant starts from the low point.
And also looking at the MACD a crossover seems very possible to the bearish side, and the RSI looks to form a head and shoulders pattern which is also a bearish signal.
