bots may make the trading game interesting for the most part.... the example of what i think may be a bot trading pattern, didn't change the average price, or the overall trend. what i would worry about with a bot, is if somebody comes up with a bot that consistently moves the price up or down on a certain coin, and uses it to gain leverage.... if that were to happen with regular stocks and bonds. it would be illegal.... 

what it looked like to me on the graph i posted, was a bot doing trades within a very narrow trading range at low volumes, but enough to skim a small percentage off of each trade, which, accordint to the volume graph is probably "small potatoes", but probably a significant margin for the person running the bot.... turning a few hundredths of a DGC into a few tenths of a DGC in the space of two hours. it also may only work on a small scale because of the effects of volume.
