We’ve seen the Bitcoin ecosystem mature in many ways over the past year. Here are some of the most important Bitcoin trends of 2015: Bitcoin transactions per day more than doubled In December 2014, the Bitcoin network averaged 86,038 transactions per day. In December 2015, the Bitcoin network averaged 202,869 transactions per day (as of 12/23/15). This means that daily transactions on the bitcoin network more than doubled (136% growth year over year) in 2015. Despite the strong growth in transactions, no single use case has broken out to the mainstream. This is something to keep an eye on in 2016 and beyond.
