Dont do it, the only legit bot that is running right now is GunBot and Cat, they are the only ones who are not scam at the moment.

They are very expensive, but it is worth it if you are really going to be trading with a good amount of money (i am not talking about $100 or $200)
The bot is over $1200, so yes, you would need to be trading with over $5000 a month in order to make a little profit every month.

But be careful about in where do you look for bots, the ones who are pretty cheap, are scam, and it is easy to know that.
