I don't think anyone knows how high this is going to go, it's just a guessing game. If someone knew the exact exit price they could patten it and then move over Bill Gates, lol.
Balance what you expect you can get from this play with what you want. Shoot in the middle and you should be safe. If it runs the way many of us think, plan to protect your investment as soon as you can and ride free shares. That's just my opinion.
