Bitcoin Production Will Drop By Half In July, How Will That Affect The Price? One of the most fascinating aspects of the Bitcoin narrative is the trajectory of its price. Since its birth seven years ago, this abstract currency that only exists as computer code and/or in a small but rabid collective conscious has gone from completely worthless to almost $450 for a single Bitcoin.
Bitcoins prices are relatively stable until the next boom begins. Notice that each turn of the cycle has left Bitcoin's price significantly higher than it was before. From an early 2011 price of $0.75, the price stabilized at $5 in early 2012, at $13.50 in early 2013, at $130 in late 2013, and at $900 today.
