I said what I did not to rain on anyone's parade as I am a significant holder of shares in the company myself.
My point is (and I think most older people like myself would agree), that many times in life the bet laid plans and endeavors in investing and other ventures in general can go awry because of unforeseen circumstances and events which can literally pull the rug out from the venture suddenly and without warning-if the endeavor includes money and others are also involved in its pursuit, imo the odds of hurdles and obstacles increase.
If Ocata existed in a vacuum, meaning they had unlimited funds from somewhere, no possible competition, an accommodating FDA, Big Pharma and politicians, and in general it was just a matter of time before everything came to fruition, I and just everyone else would go full steam ahead and would even more shares than we do.
