I want to say around $2,500 to $3,000 a coin but that is being optimistic, years go by pretty darn fast and we may just be at $1,000 a coin (not that it would be a terribly bad thing). Just remember Bitcoin isn't a race to wealth.
You are very optimistic, the bitcoin through the years has been changed a lot. the Technology is moving forward fast too.
So the price i dont think will reach 3k
