Why? Ummm, because it has the potential to make you a millionaire.
IMO if you can you should hold 1,000,000 shares. Then anything above that I would trade as you see fit.
The core position enables you to become wealthy.
At these levels, the risk vs. reward is just too high not to take a chance.
If people can spend a $1000 on Mega Millions tickets when the jackpot was $600MM, then I would definitely place my bets on GDSM.
