Eli Ben-Sasson, co-founder of Starknet, has ignited a debate within the cryptocurrency community by arguing that Bitcoin’s fixed supply of 21 million coins is not a sustainable long-term model. In a recent post on X, Ben-Sasson suggested that Bitcoin’s monetary policy should include a maximum annual inflation rate of 4% to account for the inevitable loss of coins due to misplaced private keys.
The Argument Against a Fixed Supply
Ben-Sasson’s central thesis is that over an infinite timeline, the amount of permanently lost Bitcoin will continue to grow. Lost private keys, forgotten wallets, and inaccessible coins reduce the effective circulating supply, which could eventually lead to a deflationary spiral or liquidity crisis. He argued that a clear monetary policy with a cap on the issuance rate—rather than a hard cap on total supply—would maintain a sufficient circulating supply to support a growing global population and economy.
Bitcoin’s Current Monetary Policy
Bitcoin’s supply schedule is programmed to halve the block reward approximately every four years, with the final Bitcoin expected to be mined around the year 2140. This deflationary model is a core tenet of Bitcoin’s value proposition, often described as “digital gold.” Proponents argue that its fixed supply protects against inflationary debasement by central banks. However, critics like Ben-Sasson point out that this model does not account for lost coins, which could become a significant factor over centuries.
Why the Proposal Matters
This proposal challenges a foundational principle of Bitcoin. If adopted, it would represent a fundamental shift in the network’s monetary policy, requiring a contentious hard fork and widespread consensus among miners, developers, and users. The debate touches on deeper questions about what money is, how it should be governed, and whether a rigid, unchangeable supply is truly optimal for a global currency.
Reactions and Counterarguments
The cryptocurrency community has responded with a mix of skepticism and interest. Many Bitcoin maximalists argue that the fixed supply is precisely what gives Bitcoin its value, and that any change would destroy trust in the network. Others point out that lost coins are a feature, not a bug, as they effectively increase the value of remaining coins. Some economists note that a 4% annual inflation rate is significantly higher than the current inflation rate of many fiat currencies, which could be seen as a step backward.
Conclusion
While Eli Ben-Sasson’s proposal is unlikely to gain immediate traction within the Bitcoin community, it raises important questions about the long-term viability of a fixed-supply digital currency. As the cryptocurrency ecosystem matures, debates like this will become increasingly relevant, forcing stakeholders to consider how monetary policy should evolve over centuries, not just years.
FAQs
Q1: What is the current Bitcoin supply cap?
A1: Bitcoin has a hard cap of 21 million coins, with the last coin expected to be mined around the year 2140. The supply is controlled by a halving event every four years.
Q2: How many Bitcoin are estimated to be lost?
A2: Estimates vary, but it is widely believed that between 3 to 4 million Bitcoin have been permanently lost due to forgotten private keys, lost wallets, or deceased owners. This represents roughly 15-20% of the total supply.
Q3: Could Bitcoin’s monetary policy actually change?
A3: Changing Bitcoin’s monetary policy would require a hard fork, meaning the network would split into two separate chains. This is highly unlikely to gain consensus, as the fixed supply is a core principle of Bitcoin’s design and value proposition.
