I purchased a total of 10BTC for an average price of $300 per BTC. Thus I invested $3000.  I let the Robot do it's thing.  I now have a total of 3.2 BTC for a total of about $3000.  Had I just left the BTC alone I would now have still 10BTC for a total of about $9200.  Looking at the buys and sells (hundreds of them) over the past months by the BTC, it appears that the robot buys and sells at innapropriate times.  A robot is supposed to look at trends. There are many indicators of a buy and many for a sell.  If the value of the BTC is going down and you expect it to go up you buy. If the value is going up and you expect it to go down lower then you sell. With each successful transaction you should be improving your lot. At some point you may have more USD and at some point more BTC, but your profit should ideally be going up. The robot is supposed to prevent large losses and maximize profits. In the case of the BTCRobot it has failed. The only reason that my total is not down is the fact that BTC has  increased so rapidly. My profit is in spite of, rather than due to the BTCRobot.
