American Users of Bitcoin Exchange Poloniex Will Be Deprived of Margin Trading

Cryptocurrency exchange Poloniex will deprive US users of margin trading and lending option by the end of the year.
As the trading platform blog says, Poloniex is eager to comply with regulatory requirements in every jurisdiction.
The exchange representatives have also noted that the final date will be provided in the coming weeks.

It is also said that existing loans will remain open and continue to fund positions and earn interest for their previously specified duration.

The exchange announced delisting of Synereo (AMP), Expanse (EXP) and Gnosis (GNO). The users have to close out any trades in these assets until October, 10th. They will have 30 days to withdraw these coins to third-party wallets.
To recap. Poloniex delisted 8 cryptocurrencies at the same time a month ago: BitcoinDark (BTCD), Bitmark (BTM), Einsteinium (EMC2), GridCoin (GRC), NeosCoin (NEOS), PotCoin (POT), VeriCoin (VRC), Bitcoin Plus (XBC).
