Ethereum co-founder Vitalik Buterin is known for his minimalist lifestyle in Singapore, where he frequently visits the National University of Singapore's blockchain research center. In the afternoons, he works on Ethereum Improvement Proposals at a local café, 'Plain Vanilla'. Buterin resides in a modest apartment in Tiong Bahru, with a monthly rent between 5,000 and 7,000 SGD, a modest choice given his financial status. He commutes using public transport and walks, often seen without any security detail, reflecting his preference for simplicity and practicality.
