Until nation-states fund and invest in the infrastructure, finding your confidence in cryptocurrency with little to no regulation is a massive risk.
There are many arguments against bitcoin, but I have a hard time investing in this one.
A lot of the people investing in bitcoin are doing so specifically to hedge against nation-states. It is decentralized FOSS based on sound mathematics. If this was really a concern, wouldn't people be skeptical of TLS to access your bank? One of the most popular TLS algorithms was written largely by DJB (not a nation-state).
If you had the choice of receiving BTC from a brand new minted batch, or from a darknet market, which would you prefer? If you have a preference, then they do not have the same value.
I would value BTC from a darknet market less because of risks associated with spending it.
I would value freshly-minted BTC because it doesn't have any question about its providence.
