Best ways to incentivise traders for their engagements?

Twitter recently went agog with novel revenue-sharing, as users gained hundreds to thousands of USD rewards for their engagements on the platform; a win-win situation that drove the platform to record a growth in engagements.

Coming to the crypto market, it is arguable that traders are the heartbeat of the crypto market, since they inject funds that keep the market going. But are they well renumerated by crypto exchanges for their engagements?

Would you propose exchanges to integrate similar approach as Twitter ? or are there already such events that are meant to incentivize users for their contributions?
