According to Michaël van de Poppe, the cryptocurrencies SEI ($SEI) and Optimism ($OP) are showing strong technical signals for a potential price increase. Van de Poppe's analysis indicates that both altcoins have confirmed a bullish divergence on their price charts. This technical pattern, where price forms a lower low while an oscillator forms a higher low, often suggests that downward price momentum is fading and that a trend reversal to the upside may be imminent, presenting a potential buying opportunity for traders.
