What is the expected APR on Earn?
Also, if you want to payout more dividends down the road, you could allocate 10% of your HP to other projects which gives tokens who also gives dividends or pays out in hive.
Like an added bonus or so and/or if you don't want to give it to every user, you could make a tier system. Just jamming ideas :D
