The first Bitcoin halving takes place, reducing the bitcoin mining rewards from 50 to 25 BTC

The Bitcoin community celebrated "halving day," a major milestone marking the 210,000th block mined, thereby reducing the Bitcoin created per block from 50BTC to 25BTC. 

“Today marks a major milestone for Bitcoiners everywhere.  As a community, we negotiated this deflationary moment gracefully and without major incident.” said Peter Vessenes, Executive Director of the Bitcoin Foundation.  “The excitement in the Bitcoin community is palpable - it seems we all really do believe in deflation.”
