Bitcoin (BTC) is experiencing a notable bullish divergence, which is only its second occurrence on record, indicating a potential price surge towards $90,000. This divergence arises as Bitcoin's prices fall while its momentum, as indicated by the relative strength index (RSI), shows improvement. Currently, the RSI is above 34 after previously dipping below the oversold threshold of 30. The cryptocurrency is also trading near its 200-week simple moving average (SMA) at around $62,000, a level that has historically served as a bottom during previous bear markets in 2015, 2018, and 2020. Analyst Michael van de Poppe emphasizes that breaking the resistance level between $64,000 and $65,000 could propel Bitcoin towards higher targets, including $71,500-$73,000 and potentially reaching the $90,000 mark. However, Bitcoin is also facing downside risks due to a breakdown from a weekly bear flag pattern, which could lead to a price drop below $50,000 if the bearish trend continues.
