## Feature Obsolescence

Feature obsolescence occurs when the variables or data points used as inputs for a model lose their predictive power. In cryptocurrency, a feature like on-chain transaction volume might become less relevant if users move to layer-two solutions.

If the model continues to rely on this feature, its performance will suffer. This is a common issue as the underlying technology of the crypto ecosystem evolves.

Developers must continuously review their feature sets to ensure they remain relevant to current market structure. Removing obsolete features and adding new ones is a necessary part of model maintenance.

It requires a deep understanding of the tokenomics and technical architecture of the assets being traded.
