As someone who's owned it since it was below $5 I can tell you its always been that way. Your not buying the fundamentals your buying the potential as simple as that sounds many investors have a hard time grasping that and therefore will never partake in these type of companies. You have to choose which side of the line you are on. If your a traditionalist you may want to allocate a very small amount of capital or % of your portfolio, in case it continues to grow. If your risk taker then again you may want to cut down on your position size in case that selloff you want takes place. Thats the best opinion I can give you.
