A recent report from The Defiant reveals that Coinbase holds a substantial 11% of the total Bitcoin supply, totaling approximately 2.275 million BTC worth around $129 billion.
As the world’s fourth-largest cryptocurrency exchange, Coinbase commands significant trading volume — $1.5 billion in 24-hour transactions and 34 million monthly users — and serves as a custodian for major corporations including BlackRock, Tesla and MicroStrategy.
However, this substantial concentration of Bitcoin within a single entity has raised important questions about the potential risks associated with such centralization.
The consequences of a potential Coinbase disaster
According to reportCritics argue that a significant concentration of assets could lead to systemic risks, especially if the exchange faces security issues, legal pressures or other crises.

Jameson Lopp, CTO of multi-sig custodian Casa, points out that while Coinbase is considered more stable than many exchangesremains vulnerable to pressure from nation states and could face scenarios similar to the historic US government gold seizure during the 1930s.
The implications of a Coinbase disaster—such as a hack that results in the loss of customer funds—could reverberate throughout the cryptocurrency market. Such an event would not only undermine public confidence in crypto, but could also lead to a significant drop in market pricespotentially triggering a prolonged bear market.
The report notes that the fear is compounded by the fact that more than 73 million Americans have accounts on the platform, meaning the fallout could affect a large number of retail investors.
Could a Bitcoin fork be on the horizon?
While some experts, such as Steven Lubka of Swan Private, believe a catastrophic loss is unlikely due to Coinbase’s “advanced security measures,” the risk of centralized custody remains a concern.
The idea of a Bitcoin fork to recover lost assets – similar to Ethereum’s situation after the 2016 DAO hack – has been floated. However, experts believe that while influential stakeholders could push for a rollback to “recover” their funds, the decentralized nature of the Bitcoin network would likely reject such proposals.
Lisa Neigut, founder of Base58, explains that Bitcoin’s unique Unspent Transaction Output (UTXO) model creates a buffer against centralized risk. In this model, if a bug affects a specific entity’s keys, it will only affect that entity, preserving the overall integrity of the network.
This separation of concerns is crucial to maintaining the health of the Bitcoin protocol, especially in the face of potential centralization threats. However, concerns remain about how large custodians like Coinbase could influence the broader ecosystem.

Armin Sabouri, CTO of Botanix Labs, warns that significant holders could coerce the community by threatening to dump their assets, potentially driving down the market price and forcing the network ossify in response to their demands. This scenario poses a direct challenge to Bitcoin’s fundamental spirit of decentralization.
In short, the perceived risk associated with the increased amount of holdings that the exchange represents remains a topic of debate for the future of the market. Furthermore, with the increasing number of methods to potentially hack or attempt to hack exchanges like Coinbase, it would be imperative to monitor and prevent these types of scenarios to avoid another Monte.
At the time of writing, Bitcoin is trading at $57,650, having failed to break above the $58,000 resistance level for two consecutive days.
