The staking-as-mining mechanism of a project may face reward decay issues. In Proof-of-Stake (PoS) systems, rewards often decrease over time due to factors like increasing staking participation, which dilutes individual returns, or programmed reward reductions, as seen in some blockchains like Cardano, where rewards decay each epoch. High staking ratios or inflation models can further reduce yields. To assess a specific project, check its tokenomics, staking ratio, and reward structure. Diversifying across validators or monitoring network fees can mitigate decay risks. Always research the project's long-term sustainability.
