When Satoshi Nakamoto designed Bitcoin in 2008, the code included a mechanism that exists in no other monetary system in history: a programmed and predictable reduction in the issuance rate. That mechanism is the halving, and it is perhaps Bitcoin's most important feature as a store of value.
How it works is simple. Miners are the network's nodes that verify transactions and add them to the blockchain. In exchange for that work, they receive a Bitcoin reward for each block they mine (one block roughly every 10 minutes). That reward started at 50 BTC in 2009. Every 210,000 blocks (about 4 years), the reward is cut in half.
In April 2024 the fourth halving took place. The reward went from 6.25 BTC to 3.125 BTC per block. That means the market receives roughly 450 new BTC each day, versus the 900 it received before the halving. New supply has been cut in half, but demand keeps growing.
The historical data is fascinating. After the first halving in 2012, Bitcoin went from $12 to $1,200 in twelve months (+9,900%). After the second in 2016, from $650 to $20,000 (+2,900%). After the third in 2020, from $9,000 to $69,000 (+666%), marking a new all-time high each cycle. Each cycle has its own characteristics, but the post-halving appreciation pattern is consistent.
The reason for this pattern is basic supply-and-demand economics. If Bitcoin demand grows steadily (more investors, more companies, more countries adopting it) while new supply is cut in half, the equilibrium price has to rise.
But there's something deeper. The halving doesn't just affect price; it affects mining economics. When the reward drops, the least efficient miners stop being profitable and switch off their machines. This causes a temporary correction in network difficulty, which adjusts automatically every 2,016 blocks. The result is a network that becomes more efficient and more decentralised with each cycle.
For corporate treasuries, the halving is an external catalyst that reinforces their thesis. They didn't buy Bitcoin because they anticipated the halving; they bought because they believe in programmed scarcity as the foundation of value. The halving is the quadrennial confirmation that this scarcity is real, mathematical and permanent.
In 2140, the last Bitcoin will be mined. From that point, miners will be rewarded solely by transaction fees. By then, if the network works as its designers anticipated, there will be enough economic activity for those fees to suffice. It is the most audacious monetary experiment in history.
