Thanks you for your mention. First, this is a bid bot. It is welcome any one to join the bid. The original purpose is that the bot vote my post. At that time, I use biding to trigger the bot to vote my post. After a while, there are other participants joining the bid. I am very welcome. The last modified time is more than one year. Although I send 0.1 steem each round at that time, other participants still earn a lot. Second, the bid bot does not guarantee that ROI must be positive. Third, all steem power in sleepagent is my investment. I want to maximal earn steem. However, as the steem value drop too much and I have a long period do not pay attention on my system. I forgot to adjust the setting to make sure other user can earn. This is my fault. Please waiting for adjustment. I need a time to modify the system.
