According to Michaël van de Poppe, Bitcoin and Altcoins, identified as high beta risk assets, are experiencing significant upward movement. He suggests this is an opportune moment to 'buy the dip' amid current market conditions. This advice is based on the observed market behavior, where these cryptocurrencies tend to rise sharply following periods of decline, highlighting their high volatility and potential for substantial returns. Investors are advised to focus on these trends and cut out market noise for better trading decisions.
