Justin Bons, the founder and CIO of Cyber Capital, has issued a stark warning about Bitcoin’s (BTC) future, predicting that the world’s largest cryptocurrency could collapse in the coming years. The crypto founder has cited Bitcoin’s declining security model and shrinking block rewards as some of the indicators of this seemingly inevitable crash.
Bitcoin Forecasted To Collapse Within 7-11 Years
This week, the crypto community was shaken by a striking prediction from Bons, who warned that Bitcoin could face a catastrophic collapse within the next decade. According to an X social media post released by the Cyber Capital founder, the foundations of Bitcoin’s security model are fundamentally broken, and the decline of mining revenue will eventually leave the network increasingly vulnerable to attacks.
Bons projected that Bitcoin’s downfall could occur precisely between 7 and 11 years, when the block rewards diminish to levels that can no longer sustain miner incentives. His reasoning is rooted in the economics of the Bitcoin protocol, which relies on a declining block subsidy over time. By 11 years from now, the reward is expected to fall to just 0.39 BTC per block, translating to roughly $2.3 billion annually at current prices. This figure, the crypto founder argues, is nowhere near enough to protect Bitcoin’s multi-trillion-dollar market capitalization.
Bons also shared two charts to reinforce his claims. The first shows mining revenue in sharp decline relative to previous years, demonstrating Bitcoin’s reliance on subsidy rather than transaction fees. The second chart reveals how the annual security budget as a percentage of market cap has fallen consistently over the years, shrinking from over 8% in 2015 to barely above 1% in 2025.
The Cyber Capital CIO also pointed out that while other chains like Ethereum have successfully transitioned toward greater fee-based security, Bitcoin has failed to adapt, leaving its miners increasingly dependent on dwindling rewards. According to his post, the consequences of this are dire. As mining becomes unprofitable, he predicts that the network’s security could simultaneously decline, opening the door to censorship, 51% attacks, and eventual chain splits.
If core developers respond by raising the supply cap beyond 21 million, Bons forecasts that this could fracture the community and destroy Bitcoin’s narrative of digital scarcity. He warned that relying on a system that demands perpetual price doubling to maintain its security forever is nothing short of “madness.”
Community Pushes Back Against BTC Crash Claims
Unsurprisingly, Bon’s foreboding forecast has sparked intense debate and contrasting views throughout the crypto community. Many members pushed back, acknowledging the concerns about a shrinking security budget but challenging the inevitability of a Bitcoin collapse.
Some argued that BTC has historically adapted to challenges and that transaction fees, along with scaling solutions, could still provide sustainable long-term security. Others suggested alternative mechanisms, such as MEV capture, sidechain fees, or even institutional miners operating at a loss to keep the network alive.
One community member raised the possibility of emergency measures like tail emissions or block size increases, citing Monero’s ongoing debate about similar solutions. Bons conceded that a tail emission might keep the chain alive but insisted it would come at the cost of Bitcoin’s core value proposition, which is fixed scarcity. In his view, such a compromise would leave BTC unable to compete against more adaptive blockchains.
