Vitalik Buterin has donated nearly $300,000 to Thailand's Khao Kheow Open Zoo, adopting Moo Deng, a pygmy hippo that inspired the MOODENG meme coin. His contribution will enhance the zoo's facilities and support wildlife programs, with an additional 88 ETH promised for ongoing projects. Despite recent market fluctuations, the MOODENG token has gained attention, reflecting Buterin's commitment to combining crypto with conservation efforts.
