In respect to price, we can see that it is not growing (and far from that), so you kinda have to check your sources.
Thank you for pointing that out, because if you didn't I would have. The statement that "bitcoin increases day by day" or words to that effect get parroted all over the forum, even when it's obvious that it's not true.
When I used to frequent the old JREF forum (for skeptics, in case you never heard of it), some of the members there used to call bitcoin a solution in search of a problem--meaning that it doesn't solve any current problems the world is having. While I don't completely agree with that, it does not surprise me in the least that bitcoin hasn't been more widely adopted than it has. The average person isn't looking for a new form of currency and would not see the purpose of paying for something in a currency that you'd have to buy somewhere and hope that volatility doesn't cause it to lose value before you can spend it.
As far as blockchain in general, I don't hear anything in real life about how it's changing the way people do things and I'm not sure if it's going to solve any problems that need solving. Granted, I'm not an expert in blockchain tech--not even close--but it's been around for 10 years now and you'd think that corporations/governments/individuals would have latched onto it by now if it would be to their advantage.
Haven't read the article OP linked to yet, but I'm going to right now.
Edit: Read it, and I liked this quote:
As with every bubble, whether it's Tulip Mania or the Californian Gold Rush, most investors lose their shirts while a fortune is being made by associated services – the advisors and marketeers can bank their cash, even if there's no gold in the river.
That's exactly what all these ICO projects are doing, promising that their tech will revolutionize whatever industry they're targeting, and the only ones who make money from them are the devs. Everyone else loses out when they're stuck with a token that's not even traded on an exchange. Can anyone show me a successful ICO where the project is actually benefiting something/someone other than the project developers?
