Best for store of wealth as it has the most secure and apolitical value proposition and the longest track record and always will. This is akin to genes which show their relevance and value not by their evolution over time but by the fact that they don't change overtime.  This is also a quality of gold which has a market cap in the trillions and is far more expensive and encumbered to transact than bitcoin will ever be. Some things are valued because they change and sometimes are valued because they don't.  Bitcoin is the latter.
