Halving day 2012 (November 28, 2012) was the day of the first subsidy halving, which occurred when block 210000 was solved. Until , the block reward would be 25 BTC instead of the original 50 BTC.

At the moment before the halving, 10,500,000 BTC had been mined, 50% of the target cap.

The block was solved by a Radeon HD 5800 after mining for less than a week. This GPU would later be sold to Chaang Noi at a significant markup on August 26, 2013. Several images of the card were posted to Bitmit, but no copies are currently known to exist.
