I think $20,000 is impossible, or at least in 2 years. Maybe in 5 years yes.
It's hilarious to read this thread in retrospect when that comment aged so poorly... with BTC reaching almost $20K in just two months later.
You never know, do you?
Yup this post shows how predictions and impossible things can be possible. This guy got proven wrong in only 2 months time. He probably already forgot about Bitcoin and will return here in 2 years time once Bitcoin will go toward $50k.
