Vitalik Buterin has adopted Moo Deng, a pygmy hippopotamus, with an 88 ETH donation to Khao Kheow Open Zoo. Moo Deng's viral fame led to a meme coin, MOODENG, which surged 70% after Buterin's donation. Buterin sold donated MOODENG tokens for charity, highlighting meme coins' potential for positive impact. Another example is MIRA, a meme coin created to support brain tumor research. These instances show how meme coins can drive charitable initiatives. #VitalikButerin #MooDeng #MemeCoin #Crypto #Charity
