Mods didn't touch that submission. Users flagged it. We can only guess why users flag things, but I suppose it was a combination of (1) users who felt it wasn't a substantive article and (2) users who are fatigued by the controversy around cryptocurrency. That controversy is many years old by now, has been discussed to death, and leads to poor-quality generic discussion (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). In case it helps, articles that are favorable about cryptocurrency get an even more hostile reception, especially anything reminiscent of the crypto-hype of 8-10 years ago.

This doesn't mean that articles on the topic can't do well on HN. It just means that the bar for substantiveness is high.
