Hive has a system that rewards users to help stabilize HBD price. HBD is supposed toi be pegged to $1 dollar and backed by HIVE total market cap, but because of the low share and liquidity HBD fluctuates a lot.

The further away from $1 the more profitable it becomes to convert. As HBD is, right now, 10% below $1 I thought it was worth the risk. It is a risk because the conversion takes 3 days to complete, and the average price is taken, so if HBD suddenly skyrockets to above $1 then you take a loss on the conversion.
