What is a better store of value in the mind of the owners?

One that gets thrown on the market after only the smallest change in the market variables? Or one that people want to hold no matter what the market does?

The price elasticity of demand for bitcoin is very small. This means the price can move a lot without leading to extra bitcoins being released from people's coffins. The bitcoin market is very shallow, which is one reason behind the relatively high price volatility.

This is a sign of strength of bitcoin, not of weakness. Bitcoin owners have no doubt about it's future!
