BTC Markets' new staking language has put a familiar crypto question back in front of Australian users: what exactly can an exchange do with assets it holds on your behalf?
BTC Markets has drawn sharp criticism from Australian crypto users after updating its Terms of Service to allow the exchange to stake certain customer assets on supported proof-of-stake networks while retaining the rewards. The change, which users said was communicated shortly before taking effect at 12:00pm AEST on April 28, 2026, has turned a routine terms update into a broader argument about consent, custody, and who should benefit when customer assets are put to work.
The core issue is not staking itself. Many exchanges and wallets offer staking products, and users often accept network risks in exchange for a share of the yield. What unsettled customers here is the balance of the arrangement. According to screenshots and discussion shared by users on Reddit, BTC Markets' updated terms allow it to stake digital assets it holds on behalf of customers, keep the rewards generated from those activities, and place staking-related risks in the customer disclosure framework.
That distinction matters because customers who leave assets on a centralized exchange are not simply storing coins in a neutral vault. They are relying on the platform's custody, internal controls, terms of service, and solvency. If the exchange can add yield-generating activity around those assets through a deemed consent process, the relationship starts to look less passive and more like an operating decision made over customer property.
It is also easy to see why the wording caused confusion. Some users initially worried that Bitcoin itself might be staked. It cannot be, at least not natively, because Bitcoin is a proof-of-work network rather than a proof-of-stake chain. The concern is more relevant to assets such as Ethereum, Solana, Cardano, Polkadot, Cosmos, or other proof-of-stake tokens that can be delegated, bonded, or otherwise used in validator activity.
The timing was another flashpoint. Reddit users discussing the email said they had only hours to review the update, withdraw assets, or close an account if they objected. For a material change involving custody and risk, that is a thin window. BTC Markets' public terms page says the company will endeavour to notify users of variations 30 days in advance, while also reserving the ability to vary terms immediately in some circumstances. That leaves customers asking why a staking provision needed such a short runway.
The backlash has been blunt. Some users described the move as "theft by fine print," while others focused on the practical lesson that has followed every major exchange failure: assets left on a platform remain exposed to platform decisions. The phrase "not your keys, not your coins" can sound tired until a terms update reminds users why it exists.
Regulators have not made a public finding on this specific change, so it would be premature to call it unlawful. But the policy question is obvious. Australia has been tightening its approach to crypto custody and platform conduct since the failures of FTX, Celsius, BlockFi, and other yield-driven businesses showed how quickly retail users can misunderstand where risk sits. If a platform keeps the upside from staking while customers carry meaningful downside, disclosure has to be clear enough for an ordinary account holder to understand before the change takes effect.
Risks Users Now Own
Staking is often marketed as a simple way to earn passive income, but the mechanics are not risk free. Proof-of-stake networks can impose penalties when validators go offline, behave improperly, or fail to meet protocol requirements. Assets may also be subject to waiting periods before they can be unstaked, and network or infrastructure failures can delay access at precisely the moment a user wants liquidity.
Those risks vary by network. Ethereum validators require 32 ETH to run directly, though exchanges pool user assets behind the scenes. Solana and other networks operate through epoch-based cycles that can affect activation and withdrawal timing. None of that is necessarily unusual. The unusual part, from the customer's perspective, is accepting those risks without receiving the rewards that normally compensate for them.
BTC Markets may argue that broad custody rights and risk disclosures are necessary to operate efficiently, manage assets securely, or prepare future products. That may be true. But if the platform stakes customer assets for its own benefit, the economics need to be as visible as the legal permission. Customers should know which assets are eligible, whether they can opt out while keeping the account open, how losses would be allocated, and whether any network rewards will ever be shared.
Lessons for Global Holders
The episode is not only an Australian story. It is a reminder that exchange risk is broader than hacks, bankruptcies, or bad trades. Terms of service can change the practical rights attached to assets sitting in an account. A holder may believe they are doing nothing more than waiting to sell later, while the platform's documents allow a wider range of activity.
For retail users, the immediate step is simple: read the updated terms, decide whether any proof-of-stake assets should remain on the exchange, and ask BTC Markets directly for written clarification if the answer is unclear. Users who want staking yield can choose services that state the reward split and risks upfront, or they can self-custody and stake directly where they have the technical ability to do so.
The larger takeaway is that custody is becoming one of crypto's most important consumer issues. Price volatility gets the headlines, but the quieter risk is control. If exchanges want customers to trust them as long-term asset platforms, they will need terms that are not just legally defensible, but commercially fair and easy to understand before users are deemed to have accepted them.
