Nice post, I have been doing this for a while now.
It is kind of important that you use a lending bot that renews your loans once they pay back. Good ones don't just give loans away at the current price, they sometimes wait for better ones. I am thinking about making a comparison between the most popular ones and benchmark them with a couple of identical Bitfinex accounts.
