Terrible article. So many suckers in this mania. 99% of people writing about, trading with, and investing in cryptocurrencies don't know how blockchain or bitcoin even works. It's worse than 1999. The hype and ignorance is astounding.
Just like the .com mania, I think there will be a huge fallout when the bubble bursts. But I also think there will be a couple dominant winners to rise from that rubble, and blockchains and cryptocurrencies will have a strong impact in future payment systems.
