Yeah but nobody will see back those numbers
For example it is indeed true that:
100$ invested in 2010 would give you back 75 millions now, but
100$ invested in 2013 (december) and you will "only" have 350$ now.
The rate of return is going down and a lot of us won't see, not million but x1000 returns.
So true, it's important to get in early. You don't even need to put that much in.
