Indeed. But there is a lot of talk about bitcoin and blockchain in general lately, and a lot of existing cryptocurrencies which are unworkable, created by people who want to get rich quick.
But me, I'm not planning on starting a coin, although I'm pretty interested in the tech behind it, albeit not enough to deep dive into the white papers and code, at least not yet. So I thought this was a nice byte-size chunk and was informative.
