As of the recently mined block 420,000 the Bitcoin network has now halved its mining subsidy from 25 Bitcoin to 12.5 Bitcoin. The first halving took the subsidy from the 50 Bitcoin reward this new world was born with to 25 Bitcoin. As always miners are still free to take less than the maximum subsidy when mining a block though few seem to ever make this choice. This second halving also marks three quarters of all Bitcoin to ever exist having been introduced into circulation. Hodl up!
