Lending is a fairly boring and non rewarding way of putting your coins into something. On top of that, Poloniex isn't exactly an exchange I recommend people to use due to them not handling support tickets and not going through verification requests. I personally always go for trading coin versus coin since you can optimally benefit from the regular volatility altcoins experience. I am not at all a fan of depending on external sources for income, so I at all times prefer to put my money/coins to work in form of trading.
