Very interesting discussion these last few posts, especially now that we are so high that a correction is ever more likely.
Perhaps things are different now vs. April but still my gut feeling is that this just sounds too good to be true (no need waste keyb strokes grilling me for posting a personal view, eh?!).

I'm quite curious and have setup a poll: http://micropoll.com/a/mpview/1146756-3814481
(cannot figure out how to embed nicely in the post...)

I've also been emailing the developer regarding a workaround for those who e.g. have to go to work and would like to have Butter Bot installed in two computers but actively running alternately in one of them.  Running several instances simultaneously is NOT recommended!
Sharing it below until a better solution such as hosting is offered, it has been confirmed as OK by the developer.
Take care

**************
Workaround for 2 chrome instances running Butterbot:
To be able to ensure Butterbot is running 24/7 I'll have to run it at work on one pc and then close it at the end of the day, reopening it at home on another pc.
I have butterbot installed on both Chromes (work / home) but configured with different API key/secret sets.
I will be activating/deactivating the API sets manually from the exchange dashboard (possible in Bitstamp, you would have to check the other exchanges) to have either one or the other instance of Butterbot actually actively trading, thus avoiding having them active simultaneously while being able to have both pcs on all the time with their respective Chromes and butterbot instances running.
