I was pretty late in the game. Bought my first full bitcoin when it was a little over $900.
When I purchase my first fraction of btc the price was around 450-500$.
But after that I have sold and buy at least 20 btc, plus I have used for my personal tx more than 100 btc!
There is not "late" in this game.
Because actually this is a pioneer technology, and we can't say if the price could skyrocket to 100.000 $ each btc in some years.
