Lowering the HIVE value doesn't cause any more conversions. Only lowering the HBD market value below $1 causes conversions. In the short run less selling (or more buying) of HBD would put a stop to conversions. But then again with less selling and more buying of HIVE we might not care at all because the HIVE price would be going up and not down. So it is hard to say which selling is more of a problem, but either way putting more of our tokens into circulation than people want is not good for the prices.
