Contradiction : Halving and Bitcoin Price

6 min de lecture

As your analytical partner, I will approach your article by separating it into two distinct phases. First, I will steelman your argument—recasting it in its most logically rigorous, economically sound, and academically defensible form, even fixing a technical misstep you made to ensure your thesis stands at its absolute strongest. Second, I will step into the role of your critic and deconstruct the hidden assumptions, economic category errors, and structural blind spots in your piece.

Part 1: The Steelman of “Bitcoin Doom”

(The strongest possible formulation of your thesis)

The core of your article addresses what academic literature calls the Bitcoin Security Budget Problem (see: Budish, 2018; Narayanan et al.). Stripped of simplified monthly hypotheticals, the airtight version of your argument flows as follows:

  1. The Security-Revenue Equilibrium: Bitcoin’s Proof-of-Work (PoW) security is an economic barrier, not a cryptographic one. The cost to execute a 51% attack or deep chain reorganization is directly bounded by the network’s total hash rate. Because miners are profit-maximizing entities, the total capital expenditure (hardware) and operational expenditure (electricity) they collectively deploy is strictly limited by their total revenue.
  2. The Geometric Decay of Subsidies: Miner revenue consists of two variables: Block Subsidies (R_block) and Transaction Fees (F_trans). Because R_block halves systematically every 210,000 blocks, it asymptotically approaches zero. Therefore, the total security budget (S) must eventually rely entirely on transaction fees.

In plain terms: as time tends toward infinity, S tends toward F_trans.

  1. The Asymptotic Dilemma: If the real purchasing power value of F_trans does not grow exponentially to replace the vanishing R_block, the total economic security budget (S) must collapse.
  2. The Network Utility Degradation: If the security budget collapses, the capital cost to acquire or rent enough hardware to attack the network drops. To maintain transaction finality against double-spending, exchanges and users must exponentially increase the number of required confirmations (N). A network where an L1 transaction requires days of confirmations to be safe from a rollback loses its utility, forcing users into centralized Layer-2 solutions or alternative assets, precipitating a structural death spiral.
  3. The Value Leak: To maintain its current security baseline, the Bitcoin ecosystem must constantly convert native tokens into fiat currency to pay external utility providers for electricity. Without a continuous, massive influx of speculative new capital or genuine transactional utility to absorb this structural selling pressure, the system’s economic equilibrium cannot hold.

Note on improving your argument: In your article, you state that Moore’s Law could compensate for the halving because hardware efficiency increases. This is actually a technical error that weakens your case. In PoW, physical hash rate is irrelevant; only the fiat cost to acquire that hash rate matters. If Moore’s Law makes ASICs twice as efficient, an attacker can also buy twice as many hashes per dollar. If the block reward halves, the security budget halves, and the dollar cost to attack the network drops by 50% regardless of how many hashes the network is executing. By correcting this, your “doom” thesis becomes even more severe: technology cannot save the security budget; only economics can.

Part 2: The Critical Counter-Analysis

(Where your thesis falls short logically and factually)

While your steelman argument is formidable, your article relies on several flawed assumptions and economic category errors that undermine its ultimate conclusion.

1. The L1 Consumer Payment Fallacy (Anachronistic Framing)

Your argument calculates transaction security using low-value transactions (“transactions de moins de 500 dollars”). You argue that if security drops, users will abandon L1 because waiting for 12 blocks for a 500-dollar transaction is impractical.

This is a strawman of Bitcoin’s modern architecture. Bitcoin’s L1 is no longer designed to be a consumer payment network; it is a high-value settlement layer.

2. The “Pyramid Scheme” Category Error

You assert that Bitcoin resembles a pyramid scheme (“à la manière des schémas pyramidaux”) because new entrants’ capital subsidizes the miners’ energy consumption. This is an incorrect application of economic definitions.

When a user buys Bitcoin, they are purchasing a share of a finite global ledger. The fact that capital flows out of the system to pay for the operational security of that ledger is no more a pyramid scheme than a traditional bank spending billions on cybersecurity, physical vaults, and clearinghouse electricity, or a sovereign nation printing money to fund a military that secures its fiat currency. It is a utility cost, not a capital re-allocation fraud.

3. Misunderstanding the Difficulty Adjustment Algorithm (DAA)

You imply that if the price doesn’t rise, miners will turn off their infrastructure and the network risks “stopping” or breaking down completely.

This ignores the core self-healing mechanism of Bitcoin: the Difficulty Adjustment. If 50% of miners turn off their machines due to unprofitability, the difficulty of mining drops by 50% within two weeks. The remaining 50% of miners suddenly become twice as profitable for the exact same energy expenditure. The network does not stall; it dynamically downscales its energy consumption until mining becomes profitable again for the most efficient players (e.g., those utilizing stranded, zero-cost renewable energy).

The real danger is a reduction in security thresholds, not a system-wide operational failure.

4. The Real Threat is Instability, Not “Lack of Security”

If you want to argue for Bitcoin’s structural failure post-subsidy, the accurate critique is not that the security budget disappears, but that a fee-only model introduces game-theoretic instability (the Carlsten et al. thesis).

When miner revenue comes entirely from transaction fees rather than a fixed block reward, the variance of rewards per block becomes highly volatile. If Block A has 100,000 dollars in fees and Block B has 5,000 dollars, miners are economically incentivized to engage in “fee sniping”—intentionally forking the blockchain to steal the high-fee transactions from the previous block rather than mining on top of it. This breaks the consensus mechanism entirely. This is a far more devastating, mathematically sound “doom” scenario than the retail security degradation you outlined.

The Verdict for Debate

Your article correctly identifies the long-term existential pivot Bitcoin must make from a subsidy-funded security model to a fee-funded security model. However, your conclusion that it is “condemned” relies on evaluating Bitcoin L1 as a retail payment system rather than an institutional settlement layer, and it mistakenly treats standard operational infrastructure costs as a pyramid mechanic.

How do you account for the transition of L1 into a pure high-fee settlement network? If institutional utility drives transaction fees to thousands of dollars per block, doesn’t your asymptotic doom scenario completely evaporate?
