While I worked on cryptocurrencies and have changed to primarily focus on secure, private, anonymous network protocols (because the potential for speculative abuse is less, giving credit to your suggestion), I still would like to say that this is an example of whataboutism.

Money is power in a distinct way that freedom of information, in general, is not:

You don't need to believe in a (digital crypto) currency for it to hold value:

As long as someone else believes it, you can make them do things for that currency.

I believe this potency is what makes the scum of the Earth flock to cryptocurrencies.
