The rise of new concepts can attract new investors to the cryptocurrency market. Metaverse - related cryptocurrencies, for example, may draw in investors interested in virtual worlds and digital economies. This influx of new capital can increase overall market liquidity. When a concept gains popularity, the demand for related cryptocurrencies rises, pushing up prices. As more developers build metaverse projects on a particular blockchain and use its native cryptocurrency, the price may increase due to increased utility. But if the market's enthusiasm wanes, or if there are issues with the implementation of the concept, the price may decline. For green cryptocurrencies, as environmental concerns grow, their popularity can rise, leading to price appreciation if they are seen as a sustainable alternative in the crypto space.
