Good tokenomics is so important but so many people get it wrong.

Dont punish, incentivise

This ensures your token can also attract liquidity from yield aggregators and that it can be used in other protocols. Buybacks are fine but only be distribute to tokenholders who do X

That X needs to be something that has an element of risk involved which a high compensation is a fair reward

$CRV lockups good example of this. increasing rewards for increasing time periods / risk.

Having your token be something portable to other protocols is also super important, particularly if the token itself is value accruing (eg xSUSHI). This makes the token attractive long term for lending as collateral can appreciate vs debt over time. Good trade there
