I made BTC on two out of three pairs with the bot during the dump.

It's not something you can click start and make money automatically unless you're lucky. You have to set up the bot specifically for each coin, taking into account trends, technicals etc... It takes me considerable time and research to find coins I want to bot-trade. Sideways markets with medium volume work best in my experience. If I am using the bot to trade on a downtrend I set a longer time period with lower buys and lower sells. If I am trading an uptrend I leave the default buy level and put a higher sell level. I also run my bots with the ability to sell for losses I am comfortable with so they can handle unexpected drops.

I do not auto-trade on Polo anymore because they have made API calls last priority in their system now. Bittrex works amazing.

I highly recommend using a demo market to test the bots with different settings on different coins to get a hang for it. I tested the bots for three weeks before I used one with real funds.
