I think that the oil analogy doesn't hold because the DHF is not wealth, HBD has no value, it is effectively backed by the demand of HIVE in the exchanges, if the buy book of HIVE has 200k USD in buy orders and we finance something with 1 million HBD actually that 1M can only get 200k USD in fund because it will drain the order books
DHF and HBD is not money and that is the whole economic problem that pushes us down, HBD directly correlates to HIVE sell pressure in a market that has low liquidity and low demand
