Thanks for the confidence, however, I'm not one to advise you as to what your comfort level should be. Thats up to you. I own shares, I like the company and its potential, so much so that I have my family in it. Nobody knows how much profit there will be, thats the kind of thing you find out after the fact. I wouldn't be in the stock if I didn't think I was going to make a profit. I could be wrong and I have been wrong many times. Its all up to you and your judgement.
Just my opinion
