Recently I became aware that Komodo is giving 5% interest to their holders. This is not POS in the traditional sense I suppose. The interest stops accruing on the account after 1 year also if the $KMD is not moved. Novel idea.
Same as Bitcore, 3% every monday on holded balance (but it's something as airdrop, need at least 10BTX in wallet). Any one know similliar projects?
