Ethereum co-founder Vitalik Buterin emphasized the need for a philosophical shift in the cryptocurrency industry during a speech at EthCC, as reported by Cointelegraph. Buterin compared the early growth of cryptocurrency to the internet's expansion through unconventional means, suggesting that while such growth was once acceptable, the now-recognized crypto ecosystem requires more thoughtful development. Buterin argued that the industry should move beyond blind expansion and focus on achieving specific properties rather than merely pursuing blockchain technologies. He highlighted the importance of building the right things to ensure the sustainable evolution of the crypto space.
