It is not trivial to think that a $600B asset that cannot be touched or used to buy daily groceries for majority of population is "useful" or taken seriously. This has never happened in our history, people will take time to adjust.
Also, some of the questions being raised are absolutely worth listening to and responding by either an explanation or changing the blockchain logic. High energy consumption, taxation, inflationary vs deflationary crypto, block sizes, abysmal transacction rates, Central bank crypto, moving BTC on Ethereum, etc are all questions worth thinking about.
It's about the money.
For the same reasons real-estate speculators care so much about real-estate.
Bitcoin might be interesting from a tech perspective, but it makes zero sense as a financial instrument. My main problem with it is the arbitrarily limited supply which doesn’t scale to adjust for a growing economy or wider adoption. Also, I don’t care for having to work with values like 0.00001 BTC.
