YFI holders used to be able to get dividends, however, at the moment they cannot unless they have deposited YFI into the YFI Vault. The YFI Vault allows holders to lock up their YFI tokens in exchange for veYFI tokens, which will entitle them to a share of the YFI tokens that are bought back by the protocol. This will allow YFI holders to earn a dividend on their YFI tokens.
