For a bunch of us, living in 3rd world countries, Bitcoin provides more value than Google and Facebook.
So I think this is ok. I don’t know why the post has a derogatory connotation.
I've heard this a lot, but I'm skeptical. It strikes me as yet another problem latched onto by Bitcoin enthusiasts so they can claim Bitcoin "solves" something (beyond providing yet another avenue for speculative investment), when the problem in question is much better solved by something else.
For instance: hyperinflation can be addressed by dollarization (either de-jure or de-facto), which is far more practical than bitcoin-ization.
I'm not an expert and may have a detail or two off, but for anyone willing to learn more, I'd recommend the podcast from Lex Friedman and Alex Gladstein for more eye opening details.
