Something being a desirable investment vehicle usually makes it an undesirable store of value: a store of value should be stable and predictable, not subject to significant changes in any direction.

These are, again, negative qualities in a store of value. A good store of value is inflates and deflates exactly as much as required to retain its backing value. Inflation means loss of value; deflation represents a liquidity risk when exiting the asset.
More generally, this is an indictment of the cryptocurrency community's basic financial literacy. You can't just call a speculative instrument a "store of value" because every who bought into it in the past two months has seen a positive return; that's just not what it is.
