Blockchain as a technology was something a lot of people were interested in. I am curious about Bitcoin - the monopoly money of the real world. The questions was simple: did you, or did you not, promote Bitcoin? Anyone who would promote a fake, un-regulated "currency" would not be someone whose opinion I care about.
Back when people were interested in Blockchains, I explained why people in tech were interested. I'm happy to explain that again now, if anyone cared. If someone thinks that's bad, they're a fool.
