According to Michaël van de Poppe, the cryptocurrency markets have experienced a substantial inflow of $300 million in Ethereum ($ETH) in a single day, indicating a strong interest from institutional investors. This highlights a potentially bullish sentiment in the market, as institutional buy-ins often signal confidence and stability in an asset. Traders should monitor these inflows, as they may indicate upcoming price movements and potential bullish trends. (Source: Michaël van de Poppe via Twitter)
