Interesting to see in the webinar that they only concentrated on the long-term best-case-scenarios. If they did, like a month, with their settings, you would make a loss. In my tests with the butter-bot, over the previous week, you would make 4%! w00t!
Of course, over the loooong term, you could replicate this success... IF btc continues to grow. Looks pretty flat at present though so no great riches to me made in the short term. Probably not enough to pay for your $497 purchase + $97/month.
Caveat emptor.
Anyway, just my 0.00003483 BTC. (USD$0.02 at current exchange rate)
Oh, and +3 rep to mjveinbergs for finding butter-bot and btcrobot!
