One thing I would note is that cryptocurrency as a cause area is independent of cryptocurrency having have a net benefit or a net harmful effect; potentially cryptocurrency could destabilize global financial systems, so if one has a less positive view on cryptocurrency, regulating cryptocurrency (whether by governments, or by self-regulation within the ecosystem) and making sure at least some cryptocurrencies have a positive impact (thus reducing the overall net harm) could still be a potential cause area.
Good point! I think I’d like to see more spelling out of how exactly it could transform things (for better or worse). With my lame understanding: once I see that cryptocurrency is a solid store of value, then I can see it potentially threatening central banks and the ability for states to generate revenue through taxes. However, I find it hard to believe governments would let cryptocurrencies get to that point—if cryptocurrencies are in fact capable of getting to that point.
Another thing that is worth pointing out with cryptocurrencies is how they interact with the digitization of the economy. In general greater digitzation may not be a bad thing. But it’s possible that cryptocurrency led digitization may make corruption easier (I’m imagining it’d behave similarly to cash).
