On June 14, the block analyst Larry Cermak said on Twitter that "the currency has stopped providing services to US users," said Twitter. In the past six months, the website has estimated an estimated 185 million visitors. At least 30 million are from the United States. This (an end of the currency service to US users) is a shocking statement that proves that regulators are cracking down on non-US exchanges. Also, please keep in mind that this news was released shortly after Bittrex and Poloniex began blocking US customers from accessing dozens of different altcoins. All of this is related, and for US customers, trading a closet with an uncertain registration status will be much more difficult.
