Poloniex will disable margin lending and borrowing for US customers by the end of 2018. Part of dealing with a US regulated exchange such as Poloniex is they must be compliant, and this often means less access for customers. Poloniex users will wonder how liquid their margin market might become after this change, and how a shallower margin market will impact overall exchange liquidity.
By the end of the year, we’re taking steps to remove our margin and lending products for US-based customers. These changes are part of our ongoing commitment to ensure that Poloniex complies with regulatory requirements in every jurisdiction … We will provide more communication in the coming weeks about the final date but it will be by the end of the year and encourage customers to take steps to unwind margin positions at their convenience. Existing loans will remain open and continue to fund positions and earn interest for their previously specified duration.
