I prefer to play it long myself. There were lots of 1%+ rates back when BTC took off. I don't have a bot doing things for me. I just pointed out the site that displays the lending rates like Poloniex should be doing themselves, but don't for some reason. When you notice a lending rate increasing though, it's been my experience that somethings about to happen. Might be a tip to sell as shorts outweigh the longs in the margin arena usually.
