While all of this is exciting, it seems that the USA will be left behind in the development of a blockchain-based "digital dollar" (USD). After all, the country has been known to be quite strict about the development of the crypto industry. With many fierce regulations against crypto and Blockchain tech, many mainstream crypto businesses and companies have decided to stop providing services to US citizens. Poloniex will no longer serve US customers, which greatly diminishes the adoption of crypto within the US. This makes me wonder whenever the US will allow a "Digital Dollar" to happen in the future or not? If it doesn't migrate to the digital realm, then I'm afraid that other countries will take the lead in the world's economy. It's a matter of being ahead in the latest technologies to obtain supremacy. If the US remains reluctant to accept Blockchain technology into its current monetary system, then it'll be left behind without a doubt.
What do you think?

This will be soon. but the way they treat libra is right. Because a business becomes too large and uncontrollable it becomes a slow and very dangerous bomb, which can threaten the financial and political situation of the United States.
But in the future, they will certainly study and set up electronic dollars as soon as they realize there is high demand. Anyway, I still trust Americans in technology, they have a lot of smart minds.
I already read the information that the US government announced the possibility of creating its own stable coin, which will actually be a digital dollar. In the United States, they finally realized that this market segment could soon be busy and they could stay on the sidelines of world technological progress. Even in India they already want to create their national stable coin, and it was the Reserve Bank of India, which is the main opponent of a decentralized cryptocurrency, that came up with this initiative.
The number of stable coins is growing and now it is the world states that begin to issue their national stable coins. This is a contradictory tendency for a decentralized cryptocurrency, however, I think that this will not be worse.
