A Poloniex loan is when investors borrow money so they can make larger purchases. When they do this through Poloniex, investors borrow money from other users. Lenders also receive interest (additional gain) from these transactions. After placing your bid, traders start using your money. Margin traders consume the leased money starting at the lowest rate and increasing. Profits can be made by buying and selling altcoins. In addition, Poloniex pays new users up to 10% of fees. Poloniex is a very easy to use and secure platform.
