24 Bitcoin ’s fixed supply schedule is driven by programmatic changes in the block reward; every 210,000 blocks (roughly every four years) the block reward is reduced by 50% (i.e., “halving”). Following each halving, Bitcoin miners receive half the Bitcoin block per block mined HISTORICAL BITCOIN PRICE AND “ HALVINGS ” 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 $1 $10 $100 $1,000 $10,000 $100,000 Jan-12 Jan-13 Jan-14 Jan-15 Jan-16 Jan-17 Jan-18 Jan-19 Jan-20 Jan-21 BTC Price (Logarithmic Scale) 2 nd Halving: Block Reward 25 to 12.5 3 rd Halving: Block Reward 12.5 to 6.25 1 st Halving: Block Reward 50 to 25 All else being equal, this results in a reduction of mining revenue. The halving mechanism results in an ever - decreasing issuanc e rate of Bitcoin as the supply asymptotically approaches its maximum supply of 21 million by July 2141. Following each historical halving, Bitcoin has experienced significant price appreciation in the ensuing 18 months BITCOIN “HALVING” OVERVIEW


Bitcoin (BTC) : a type of digital currency in which a record of transactions is maintained and new units of currency are generated by the computational solution of mathematical problems, and which operates independently of a central bank; a unit of Bitcoin Blockchain : a system in which a record of transactions made in Bitcoin or another cryptocurrency are maintained across several computers that are linked in a peer - to - peer network Block : a file that contains a “permanent” record of transactions Mining : the processing of transactions in the digital currency system, in which the records of current Bitcoin transactions, known as a blocks, are added to the record of past transactions, known as the blockchain Hash Rate : the measure of a miners performance; number of calculations a miner can perform in 1 second as it works to solve the block Block Reward : the amount of Bitcoin awarded for successfully mining / verifying a block 25 average # of Bitcoin mined each day = (Block Reward) x (6x / hour) x (24 hours / day) (6.25 BTC / Block) x (6x / hour) x (24 hours / day) = 900 Bitcoin per day on average GLOSSARY
