In the United States, Bitcoin has always been regulated by the US government. The US Commodity Futures Trading Commission (CFTC) recently issued a document saying that Bitcoin and other virtual currencies are reasonably defined as commodities, just like crude oil or wheat. This means that bitcoin futures and options must comply with CFTC regulations and be supervised. It is illegal to apply for a license to conduct bitcoin-related business in New York State. In California, the attitude towards virtual currencies such as Bitcoin is relatively friendly, but registration is required.

In the United States, it is legal to engage in illegal activities as long as virtual currency is not used. Fuyuan coins are registered in the United States, and so are precious coins. However, according to relevant media reports, China people represented by Liu Longzhu are targeting a company called Regal Group. On September 29th, China Company in Los Angeles went bankrupt. The company was accused of using a virtual currency called "Treasure Coin" to cheat investors by pyramid selling, and Jiang Kun's photo became the material for them to promote "Treasure Coin". In Chinese mainland, "rare coins" are still sold, but the sellers have not mentioned Jiang Kun to the mainland buyers.
