Something is better than nothing and you also get interest on your hive power. If the price of hive was a bit more stable hive power would be one of the best savings accounts out there.
I am going to hold hive power for as long as i can until i need the money, and look at it as a kind of saving for a house or a retirement.
It's like you say, we work here, we accumulate and if we are lucky the increase will help us get good profits, the point is to be constant and have patience.
