In my opinion, @smartsteem is the best bot out there. They have clean and neat website that is very user-friendly and easy to understand. They have -10% limit to their bid so don't you worry about losing money while using their service. Recently, I do not use much of the bid bot because of saturation of the market but I am making sure that everytime I use the bot @smartsteem is one of the bot that comes in to my mind because of their good services. Great job!
