I think crypto proponents have exaggerated the threat that cryptocurrency poses to government controlled currencies. The narrative plays well to audiences that distrust institutions and want to be early adopters of a new cryptocurrency paradigm (in which they would be at the top of the wealth spectrum), but the reality is that cryptocurrencies are additive on top of existing currencies, not replacements.
In practice, average people in average countries (e.g. not Venezuela) benefit more from having centrally controlled currencies than they lose. Average people also benefit from having an established currency rather than being forced to switch to one that is majority controlled by a few early adopters. If you think wealth inequality is bad now, the wealth inequality in a hypothetical Bitcoin economy would be orders of magnitude worse.
The idea that one day Bitcoin will reign supreme and everyone will be forced to buy 0.0000001 Bitcoin to get any transactions done is attractive to someone who wants Bitcoin prices to go the moon, but the average person wants nothing of the sort.
