Gemini co-founder Tyler Winklevoss has proposed a “marketing incentive” on the MakerDAO forum to drive the adoption of his stablecoin GUSD via a three-month strategic plan. As per the proposal, Gemini will pay monthly fixed annual interest of 1.25% on all the GUSD stored in MakerDAO PSM vaults until the average monthly balance is at least 100 million GUSD by the end of the month.
