Golden Finance reports that Vitalik discussed the budget strategy of the Ethereum Foundation (EF) in a Reddit sub-division. According to this strategy, EF spends 15% of its remaining funds annually. This approach aims to maintain the foundation's persistence and vitality. Through this annual 15% expenditure model, EF not only ensures its sustainable development but also continues to play an active role within the ecosystem framework, providing necessary support for innovation and technological advancement. However, as the years pass with spending, the scale of the foundation may gradually shrink, yet it does not affect its status and role as a key component of the ecosystem.
