Critic Says Bitcoin Will Fail in 7–11 Years: Here’s the Math

Crypto analyst Justin Bons predicts Bitcoin’s security will fail in 7-11 years as mining rewards decline and attack costs plummet.

Bitcoin could face a catastrophic security failure within the next decade. That’s according to prominent crypto analyst Justin Bons.

Bons laid out a detailed mathematical case for why Bitcoin’s current model cannot survive. The timeline? Seven to eleven years from now.

The analysis focuses on a fundamental flaw in Bitcoin’s economic design. As mining rewards shrink with each halving, network security deteriorates proportionally.

This creates a dangerous opening for attackers. Eventually, the cost of attacking Bitcoin will drop below the potential profit.

Mining Rewards Tell the Real Security Story

Many people believe hashrate measures Bitcoin’s security. Bons argues this represents a fundamental misunderstanding.

The actual security budget comes from miner revenue, not computational power. This includes block rewards and transaction fees combined.

Here’s why the distinction matters. Hardware improvements constantly reduce the cost of producing hashes.

Higher hashrate doesn’t necessarily mean stronger security. What matters is how much attackers must spend to compromise the network.

Current data shows miner revenue has actually declined over the past five years. This happened despite hashrate reaching record highs.

Bitcoin currently pays miners around $16.42 billion annually through inflation. Transaction fees add roughly $140 million more.

Each halving event cuts the inflation reward in half. After three more halvings, the economics shift dramatically.

Bons calculates the daily attack threshold could drop to just $2.88 million. For a network potentially worth trillions, that’s alarmingly low.

Double-Spending Becomes Profitable

The analyst outlines how attackers could exploit this weakness. The method involves targeting cryptocurrency exchanges through 51% attacks.

An attacker sends Bitcoin to multiple exchanges. They trade it for other cryptocurrencies or assets.

Then comes the critical move. With majority hashrate control, they reverse the blockchain.

The attacker reclaims their original Bitcoin. But they also keep everything they traded for.

Bons estimates such attacks could net billions in profit. Multiple exchanges could be hit simultaneously.

The math shows a troubling imbalance. A $1 billion investment could potentially compromise a $2 trillion network.

Nation-states might find this economically attractive. Corporate competitors could view it as a viable strategy.

The larger Bitcoin grows, the more profitable these attacks become. Market cap increases faster than security spending.

Capacity Crisis Threatens Mass Panic

Bitcoin processes approximately seven transactions per second. Bons calls this catastrophically insufficient.

Around 33 million people currently hold Bitcoin on-chain. If each made just one transaction, the queue would last nearly two months.

Global adoption would create impossible bottlenecks. A worldwide user base would face a 32-year transaction backlog.

This sets up what Bons describes as a bank-run scenario. Users cannot exit when they need to.

Panic could trigger a devastating cycle. Falling prices would force miners offline.

Fewer miners mean slower blocks. The difficulty adjustment takes two weeks of block time to recalibrate.

If half the miners shut down, blocks arrive at half speed. The adjustment period could stretch to a month.

Congestion worsens rapidly. A three-month backlog becomes six months, then a year.

Price crashes accelerate miner exits. The cycle feeds on itself.

Bons traces these problems to Bitcoin’s block size wars. He contends developers abandoned Satoshi Nakamoto’s original scaling vision.

The founder envisioned massive on-chain capacity. Current limits represent a radical departure from that plan.

Bitcoin now faces an impossible choice, according to Bons. Either inflate beyond 21 million coins or accept network attacks.

Both options undermine Bitcoin’s core promises. Neither preserves what investors believe they’re buying.

The analyst suggests Bitcoin’s governance structure prevents necessary changes. A small group of Core developers controls protocol updates.

Other cryptocurrencies have solved these scaling challenges. Bitcoin remains constrained by political decisions, not technical limitations.

Bons issued this warning despite once supporting Bitcoin’s original vision. He believes the current trajectory leads to inevitable collapse.

Whether Bitcoin adapts or faces this predicted crisis remains uncertain. The clock, according to Bons, is already ticking.
