If this is all a project has to offer run and don't look back

Staking is a use case but buying back and burning are not use cases.

Developer teams decide to do buy back and burn in order to create hypes that their teams prove that they won't abandon projects because they sacrifice their short term interest to achieve long term ones, not only for them but also for investors too.

Two most successful projects with Buy back and Burn mechanism are Ethereum and BNB (Binance coin). However, later projects follow them are not actually successful like ETH and BNB. Quality is key, not that mechanism.

Are people still stupid enough to invest their hard earned money on such crypto projects? If you are new to crypto all these aren't real use cases.

If these are all a project have to offer you better run, such projects have nothing to lose if they want to rug pull and believe me it's easier for them, they have nothing to offer in the first place.

They become stupid if they will invest in shitty projects. New crypto investors are not all have that mindset as they are now more doing the research before investing than being stupid to invest without knowing the project.

Most newly created projects offer to stake and with a huge percentage. Perhaps, this the only thing they can offered for their early investors while waiting for the final stage of the project. Usually they don't have use-case and it found risky because we have no assurance if the project will succeed or not. And doing this is a choice, not because someone pushed you to do that.
