The struggle to regulate crypto currency in the US is moving to a new level. Bitfinex Exchange in March, and the Poloniex exchange in late July reported that they suspended their activities in the state of Washington, due to the fact that the act of Congress number 5031 came into effect. Bitfinex has already recognized itself defeated not only in the state of Washington, but also in the territory of New York. And Poloniex gave the site an explanation of how users from the state of Washington can close their accounts. At the same time, many crypto-exchange markets want to expand their activities in the US, despite more stringent regulation. For example, the Gemini exchange has already received approval from its authorities, as well as a license for operations with crypto-currencies.
