Bitcoin adds a "Zero" every two years or so, or at least it has in the past...
2009 - $0
2011 - $10
2013 - $100
2015 - $1,000
2017 - $10,000
And if it were to keep going at this pace...
2019 - $100,000
2021 - $1,000,000
And you thought those guys calling for $1 million per coin were just pulling a number out of their arses! :)
