However, it is much worse for the value of the SBD or Steem if people chashen out all their reward quickly. Think about it.
I agree with you here. A lot and I mean a lot of bid bot abusers use the bots and 50/50 payouts in order to sell off a lot of liquid Steem / SBD at lower and lower prices. You are correct about this.
But my argument isn't necessarily to bid bot or not to bod bot. The question is what content we are botting. Is it good or just people's cheap attempts to make easy dollars. Most of the time I find it to be the latter.
Essentially, the premise of your posts is your are testing the profitability of bots and taking in rewards. Why stop at 10 SBD? Why not 100? Why not 1000? Now, let's imagine everybody doing the same thing. When you think in those terms, then you can see why a behavior is a problem.
When a person promotes a post, they typically promote based on the type of content. They don't use bid bots just for the sake of using bid bots which is pretty much what you are doing.
I tell you on this day. You are free to tell us you're experimenting but we don't have to buy it. From the looks, it appears you have come up with an excuse to reward yourself for useless experiments.
Again, there are far too many factors that have to do with using bid bots and for that reason the returns will be variable. Especially when users that know better see the post and flag it for "testing for rewards".
