Ethereum's co-founder Vitalik Buterin made waves by selling two altcoins: LEDOG (DOG) and Estee (ESTEE). The unexpected move led to reverse price reactions for these tokens. While Buterin's influence is massive, the selling demonstrates the unpredictability of altcoin markets. As major figures like Buterin take actions, altcoin prices continue to be sensitive to such developments. Traders and investors are closely watching these market changes, wondering what might come next from leading crypto personalities.
