I've made a good trading bot application for beginners such as yourself.
http://crabby.io/Be careful, that user is a newbie, he has no trust and he is offering a program, maybe you download that software, and tomorrow you wake up with a ramsonware or just any other trojan in your computer.
Or maybe he just puts a rat on your computer infecting all your private keys..
Be careful about in where do you buy a trader bot, because you are always going to have that issue, cause you dont know who was the guy who is behind all that script.
I appreciate your concern. I don't know how to assure you that our application is not malicious besides discussing the security we use. Our application accepts your Poloniex API keys and immediately encrypts them through well established protocols. It will never share your keys with third party applications or relay them to our servers for any reason. We also encourage our users to disable withdrawals so you can rest assured that your coins are safe on Poloniex. We don't have access to our users coins, so there is no chance of us or a third party accessing them through our application.
I don't know if this relieves your concerns, but my team and I are engineers who would not risk our livelihoods over stealing your coins.
Also, we are about to release an update to the application in the next few days, so if you have the chance we would love to hear your feedback regarding the update as well.
Happy Trading!
