Bitcoin lost 10.8%
Gold gained 60.0%
You just proved his point. In this example, bitcoin's volatility is closer to zero than gold's. Thus, by the quoted definition of "store of value", then in this particular time frame (it would be very different going back 5, 10, 15 years), bitcoin is the better store of value.
