My guess is we will be in the $1k to $2k range in 2 years time
I really hope that you are right but now this is just our hope and speculation.
We need more ''big'' merchants to accept bitcoin in next 2 years so that people can use their btc for buying more and more digital products, not mainly for investing, what is situation now.
This will stabilize the value of bitcoin and increase confidence of its users.
