A series of things have happened recently, from exchanges, wallets, nodes. Bitcoin's threat to the status of the dollar has prompted the U.S. government to take action.
In a series of international incidents, the US government found that Bitcoin had challenged the supremacy of the US dollar, SWIFT could not track and monitor these transactions, and more and more people and countries began to use Bitcoin instead of the US dollar for storage and transactions. So far, no national currency has challenged the dollar as the world's currency, because as long as you are a sovereign currency, the U.S. government can work with its Allies in the developed world to find a way to contain the development of that country, Japan in the 1980s, and China now.
But they've never had an opponent grow as fast as Bitcoin, and you can't find an entity to sanction and curb them. The original currency of the Internet, completely decentralized, is like a weed that grows when the spring breeze blows. As a result, the US government and its Allies have now imposed sanctions on all Bitcoin entities and individuals.
Under the sanctions of powerful governments and their Allies, neither individuals nor businesses are powerless, and this is where # Bitcoinman is most helpless. We have Bitcoin as the strongest shield to protect our wealth, but we cannot withstand the spears of power.
