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.
For sure. But those people probably don't bother trying to make their own implementation of the protocol. The code is out there for them to just go 'copy+paste, change a few config settings, done'. They're essentially the script kiddies of the cryptocurrency world.
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.
