POB can be sold at a higher price than Hive. It is a matter of supply and demand.
I love the aspect of demand and supply that you mention. And i will like us to look at it one after the other.
Supply
The truth is that when it comes to supply. Pob has been highly supplied and this means without a corresponding in crease in the demand for it as many people now sell the pob instantly to get hive.
The increase in the price of hive has practically make it so difficult for many to choose pob over hive especially now that hive.
DEMAND
Many want to have hive now especially when the price is lower. Knowingfully well that price of hive has once been in $1.1 dollar the believe that people now have in hive is much as many is willing to have hive and wait patiently for when it will become bullish.
I am not sure the price of hive and pob can not be the same.
