what you saw is the same thing that has happened before many many times not just in US but in all the other countries. everyone always warns people first about investing in cryptocurrencies because of their volatility which is understandable and i also do that. and then they express concerns about the fact that the unregulated and decentralized nature of bitcoin may attract the wrong crowd.
none of these mean the country is adopting bitcoin though! and more importantly it has nothing to do with the price.
