Definitely buy Call! Lottery is one in a million chances to win only and you might not even get that chance to win big in your lifetime. If it doesn't strike, you lose that cash for good. Stock on the other hand, if you analyze well about the potential of the company and did your diligent research to buy a good stock, even if the stock does not increase at that moment of purchase, there will always be another chance for it to skyrocket. Just need to be patient and have the tenacity to hold your investment. At worst, if the stock is not doing well, you can still sell and take back without incurring 100% loss.
I believe this stock would prosper despite the slight pitfall. So I'm holding on and if possible, buying more. It has potential since there are big players holding them.
