I think the narrative of Bitcoin as a "Savings Technology" is stupid because in order to be a "Savings Technology", you need it to be stable, reliable, & predictable.
Bitcoin is not stable, reliable, or predictable, it is highly volatile but on the flip side it does have high price appreciation, which is more of a growth tool, not a savings technology.
If I had 5 Bitcoin, and say needed to buy a house then I probably wouldn't be able to because Bitcoin went down this week, however if I had ~$500,000 in an Savings fund then the relative value has stayed stable, and consistent enough in relation to the house's current price that I would be able to buy a house.
