The system guarantees the price of HBD with HIVE. The HBD to HIVE convert button will destroy the HBD and create a dollar's equivalent over a 3.5 day period.

Since the value of HBD is derived from the value of HIVE it is a device called a derivative. For more information on derivatives, you might want to study a company called Enron.

Anyway, HIVE has a ten million dollar loan against HIVE that pays 20% interest a year. Because of this debt, I would not consider HIVE (or any of the coins on HIVE-Engine) to be a good investment.
