It looks like the USA is seriously preparing to launch the crypto version of the US dollar (regarding the Whitehouse)
placing urgency on research and development of a potential United States CBDC
https://www.whitehouse.gov/briefing-room/statements-releases/2022/03/09/fact-sheet-president-biden-to-sign-executive-order-on-ensuring-responsible-innovation-in-digital-assets/I believe this can be seen as a positive step towards the wider adoption of cryptocurrencies in general because of government-backed crypto is most likely going to be the one that "mainstream users" will use, simply because of it's "trusted" and "backed by the central bank". Furthermore, it's quite sure it will be easier to use than for example Bitcoin or alts.
However, this may mean that Bitcoin and alts market share declines instead of gaining more users. "Traditional" cryptocurrencies may stay in the interest of "crypto circles" as well some investors, but "mainstream" users turn back to them as there's an easier alternative to use.
Furthermore, I believe this is a leap towards a dystopian society, actually a dystopian world. The executive order directs:
agencies to work with our allies and partners to ensure international frameworks, capabilities, and partnerships are aligned and responsive to risks.
and
mitigate economy-wide (i.e., systemic) financial risks posed by digital assets and to develop appropriate policy recommendations to address any regulatory gaps.
Which in my view says directly that the US is going to lead international efforts to regulate cryptos at a detailed level, meaning ultimately they will be regulated almost in every country as tightly for example banks. This kills innovation and decentralization not to mention privacy.
