Title: Re: Bitcoin issued Post by: Charles-Tim on September 25, 2021, 07:50:20 PM Bitcoin halves every 210000 blocks while the reward was first 50 BTC which is divided by 2 after each halving.
First halving (2012), total BTC supplied 210000 * 50 BTC = 10500000 BTC Second halving (2016), total BTC supplied 210000 * 25 BTC= 5250000 Third halving (2020), total BTC supplied 210000 * 12.5 BTC = 2625000 The total supply in first, second and third halving is 18,375,000 at block 630000. Block 702182 was just mined some minutes ago which you can substrate from block 630000 to get the recently mined BTC after 2020 halving. Block 702182 - Block 630000 = 72182 blocks 72182 * the present mining reward which is 6.25 = 451137.5 Total mined as at present = 18,375,000 mined in the previous halvings + the mined blocks after block 630000 18,375,000 + 451137.5 = 18826137.5 Total mined BTC at block 702182 which was mined some minutes ago is 18,826,137.5 which is the circulatory supply. Bitcoin mining reward is 10 minutes on average.

It'd be correct if it was mandatory, by a consensus rule, for each block to have a specific reward in each epoch. But, a miner can choose to issue no bitcoins if they want to. They're free to secure the network by only acquiring the network fees or even dumping those too; although none does.However, there have been cases where the miner lost the block reward either by accident or intentionally. Check block 124,724 (https://blockchair.com/bitcoin/block/124724). The miner destroyed 0.01000001 by deciding to earn 1 satoshi less from the block reward and by burning the fees.
