Definition: Bitcoin prices

Following are samples of Bitcoin valuations since 2017, which is the year that the world took notice because of its more than 10x increase within nine months. However, there was an even more dramatic increase before 2017. Bitcoin was launched in 2009 and it rose from 30 cents in 2010 to more than $25 by mid-2011. Bitcoin had only been around a couple years and most people had never even heard of cryptocurrencies. See Bitcoin.
