Money has more utility when it flows, so I think a HODLing culture is actually actively damaging to a small extent.

An reasonably priced Hive coin with loads of liquidity will stimulate development of new games on the platform, whereas a boom $20 Hive will most likely cause most active people to simply sell, the whole platform to be overtaken by greed, and several games being priced outside reasonable budget ranges.

So even though I hold Hive/LEO, I think people do well to sell if they feel it's overpriced!
