The more I think about it, the dumber I feel for thinking the attacks on bitcoin would come from outside. Trojan horse from within is the easiest way but takes a bit more patience (incrementalism is THE tried and true tactic)
Its fashionable to dump on governments, but the modern nation state is the result of at least 500 years of intense competition that included the development of spy craft and central banks. They have different priorities than us little citizens, and they excel at the things they prioritize.
By incrementalism, do you mean the growing computer power to break, alter, rewrite (in one's favour),... the history of the Bitcoin ledger. I remember Guy Swann (Bitcoin Audible Podcast: "The guy who has read more on Bitcoin than...) or Jack Spirko (the of ~16-year running Survival Podcast, and recent Bitcoin Breakout podcast) Supposedly what quantum computing is all about or will do???
If you would ever have the patience to expand on the trojan horse scenario, i at least would be interested in hearing.
