Yes, post, comments, and snaps.
Setting those to 100% powerup will do it.
When you choose 50/50, some hive is sold at payout automatically to pay for the hbd that you get, in effect shorting hive while the price is low.
When the price gets back over .5usd I will start looking at trading some hive for hbd from the rewards payouts.
Until then, maximizing calls for 100% powerup.
