The right bots are a very very good thing.
Please note: DnnBitcoin went down only about a week before the pop. There would have been a ton of coins automatically bought and sold during the pop, if there had been more botters online. That would bring more stability, and more liquidity, smaller margins, more competition. Hell, I'll pay somebody $500 if they fix DNNBitcoin and make it public again. =) It's simple - you know the market manipulators want to move that price up and down for profit... that's a hell of a lot harder and more expensive when there are thousands of small bot orders in between the MMs and their margins. =)
Good point well made botlove, they do add inertia and depth to the market, making it more difficult for price manipulators.
P.S.
If you've employed bots on DNNBitcoin then you are breaking "MKEGuy's law" as stipulated in first post
