by 2020 it will probably be somewhere in the 5 digits.
Hard to tell exactly though.
Yeah so hard to tell exactly especially if your expectations really unrealistic and can't even support in any other means. Speculating is good but please make it to realistic. If that will happen then Im surely pissed off of what I replied to this post.
Sarcasm on point. Bitcoin has been playing around 430$ at the moment. Pretty sure it will not jump to 10,000$+ after 4 years. It might reach 900$+ to 1000$+ in 4 years but not near 5 digits.
