Just a new updated reference to those who wanted a chart since 2013.
The mining block reward on bitcoin cuts 50 percent every 4 years.
50 to 25 Block reward 2012
25 to 12.5 block reward 2016
12.5 to 6.25 block reward 2020
I am not a financial adviser. This is a long term chart of bitcoin , I included include the 2014-2015 bear market and channel of price action over the long term.
Hodl and peace
