i don't think it can get there this year. so it can even take until late 2017 to reach $4000 if everything goes right.
What kind of "everything goes right" scenario you are thinking that can bring the price to $4000 until late 2017 or I will extend it until 2020.
Being a bitcoin believer is normal but don't desire too much.
you still don't get it do you?
let me make this as simple as possible for you
21 million bitcoin
7.4 billion people.
trillions of dollars.
some simple calculations would tell you that bitcoin is way undervalued right now, and $4000 is just the beginning.
and it's not going to take 200 years to get adoption, just like facebook didn't need 200 years for it to gain a couple of billion users.
it's more likely going to take 5 years, 10 years maybe, at most.
not 200, not 20, just 5.
