Fish, it's funny you should ask that question because I had to ask myself the same question about some of my other "non-stellar" poorly performing stocks. For me, it was a matter of how long would it take to recuperate my losses in the other stocks. My conclusion was that FUSZ has so much more potential than my other stocks ever would that I could theoretically regain all my losses quicker by selling them to buy FUSZ stock.

This is by no means what you should necessarily do, but just my thought process I went through to make my decision. Hope this helps.
