Lower inflation rate than gold, can't be faked, and this year actually became so much recognized and even legit enough for government mafia to adopt it as a reserve currency.
What else would you suggest? There isn't any other crypto with a bigger network of validators, longer history, no rug-pull risk, lower inflation, bigger network effect than BTC.
Smart contracts, better tech, upgrades etc. don't matter regarding value preservation - look at ETH -> it gets continuously upgraded, even had negative inflation at a point (no idea where it's now at, got rid of my last ETH at $3600 when it became clear that it's not heading to 7K, and never looked back)., and it's getting smashed, coz there is more and more competition -> substitution.
What else can you use as a store of value - gold, silver, diamonds, uranium, platinum, oil, microchips, paper fiat money, etc? You can get more of all of them with time through mining/manifacture- at a higher inflationary rate than BTC.
And their use case can disappear - as pretty much all of them can be substituted with something else - see platinum/palladium for vehicles.
