Vitalik Buterin said simply paying users through token incentives is not enough to ensure the long-term success of crypto applications. The Ethereum co-founder argued that projects relying heavily on financial rewards often struggle to retain users once incentives decline. He emphasized the need for apps to deliver genuine utility, strong product design, and sustainable value beyond speculation. Buterin added that meaningful adoption will come from building tools people actually want to use, rather than depending solely on short-term token rewards.
