Bitcoin worth anything above $0 would have been an absurd thought 10 years ago, now it's a global asset class worth hundreds of billions of dollars. Unstoppable money not backed by any state is an amazing accomplishment. This alone is a mind blowing fact to me, but again, to the HN crypto hater it's meaningless, because the definition of "success" is constantly moving.
Blockchain and finance are deeply intertwined, so a lot of applications built on digital financial rails (blockchains) are naturally around capital formation, derivatives, trading, etc. but to the socialist / statist that should be outlawed (not just in crypto but likely Wall Street itself) so that isn't anything to you.
One counterpoint is the HN shibboleth of Stripe. Stripe is barely a tweak on PayPal, or at least it was at first, yet everyone on HN ejaculated in amazement at the ability to take a credit card with a javascript function. Of course I think Stripe is a great company, I just want to put into context how on HackerNews, Stripe = "Amazing incredible glorious $100 billion epic company" and cryptocurrency = "Wow a trillion dollar asset built on pure computer science and economic principles created by mysterious cypherpunk, who cares".
