Lending cryptocurrencies: why such interest rates?

[dimanyc]

Any thoughts on crypto lending through exchanges like Poloniex? Why do we see interest rates on some currencies so high? For instance, i.r. on Stellar today is close to 1.4%... per day. Why so high for this particular currency? What is this an indicator of? Interest Rate on bitcoin is dropping and that's understandable. People want to sit out segwit and aren't interested in borrowing BTC for now. But some currencies like Stellar of Doge really surprise me. Any explanation to this?
