According to Michaël van de Poppe, the real expansion of the altcoin market is yet to occur, with significant growth expected in 2025. He notes that the altcoin market capitalization is currently at $280 billion and suggests it could potentially achieve a 10x increase within the next 12-24 months, based on historical bull cycle patterns. This projection is important for traders considering long-term investments in altcoins, as it implies substantial market growth ahead. [Source: @CryptoMichNL on Twitter]
