Bitcoin has proven itself to be trustworthy, in less than two decades of it's creation it has gained so much reputation that it is called digital gold which clearly means that it is widely accepted as a store of value. Many currencies have been affected by inflation, it is easy for a government to print more fiat thereby devaluing their currency but Bitcoin limited supply has given it trust and people can hold it for long term instead of traditional currencies in a bank. Bitcoin can react to negative news and dip but it will only be for a short term and it will recover and rally, that is why it is a valued asset.
Though the population who are into crypto is still small as compared to world's population, it is already gaining interest from big companies and so penetrating the mainstream financial market. We can't deny the fact that a big companies are already accumulating btc as part of their assets. Though some are silent with their holdings, but I do believe that a lot are just quietly holding their crypto.
