How is (crypto) interest generated from cryptocurrencies taxed? When?

Question as title. Assuming I have some crypto and this crypto is part of a scheme that gives you "dividends" (kind of like staking) every once in a while. This dividend/interest earned is paid in that specific crypto token and not converted into fiat.

Would it be reported/taxed when the dividend "vests", or is it only a taxable event once I decide to sell it (or change it for another currency). In that case I assume it would be taxed as any other crypto but with the base acquired price of 0? Am I correct?
