I don't offer high returns like that as I do micro trading and lending on poloniex, I have a lending bot written that you could use and make profit yourself or use my own service if your interested links are below.

Interesting! Two different products on offer, right? I think that 5$ Python stuff is safe to use.
However I've made up my mind after some C.A.T and Spreadbot experience. Trading against the fees could have worked in china, because of zilch fees over there. Not in our area. And the automized arbitrage between Mintpal, Bittrex and Cryptsy well that worked for some monthes. Most of these sites scammed out now. Lost a chunk of my money, would have had to install a bazillion shitcoin wallets (and infect my desktop along that way) to rescue any funds timely.
