Mercado Bitcoin (MB) announced a security incident on Monday (2) and suspended deposits and withdrawals as a precautionary measure, according to Money Times Cripto. The company has not disclosed the amount affected: the $40 million figure appearing in the media headline comes from independent blockchain activity trackers, not an official number. For anyone with a balance on the exchange, the immediate practical effect is straightforward: you cannot withdraw or deposit funds for the time being.
What Did Mercado Bitcoin Say About the Incident?
The exchange notified clients and the market on Monday morning. The excerpt of the statement reproduced by Money Times Cripto is brief and goes straight to the practical consequence:
“As a preventive protection measure, deposits and withdrawals have been temporarily suspended.”Mercado Bitcoin statement, according to Money Times Cripto
Note the wording chosen by the company itself. It refers to a “security incident”; the media outlet uses the term “hacker attack” in its headline. The company also describes the measure as “preventive” and “temporary.” However, the quoted excerpt provides no timeline for resumption, and that timeline is what determines how long your balance remains frozen.
- A security incident occurred, as communicated by the company itself on Monday (2).
- Deposits and withdrawals are suspended as a preventive and temporary measure.
- Unofficial on-chain trackers estimate the amount involved.
- The official figure: the company has not disclosed it.
- Whether the affected funds belonged to clients or the exchange itself: the reporting does not clarify.
- When withdrawals and deposits will resume.
The right-hand column outweighs the left. Today, there are more unanswered questions than confirmed facts, and any interpretation filling in those gaps would be mere guesswork.
Where Does the $40 Million Figure Come From, and How Reliable Is It?
The “trackers” mentioned in the report are tools and analysts that monitor publicly recorded transfers on blockchains in real time. Anyone can see the destination address for a cryptocurrency transfer. Consequently, when something unusual happens at an exchange, these trackers are typically the first to point to a figure.
The limitation lies in what this type of tracking shows. It reveals the movement, but it does not indicate whose money it was, nor whether the exchange has the means to cover the loss. And as Money Times Cripto itself points out, the official amount has not been disclosed. Treat the figure as a provisional order of magnitude: it could rise or fall once the exchange publishes its accounting.
Is My Money Locked? What This Means for MB Crypto Holders
For now, yes, in terms of access: with withdrawals suspended, balances sitting on the exchange cannot leave it. This applies to both cryptocurrencies and reais. Anyone who leaves assets on the platform depends on it to move them, and this episode lays bare precisely that dependency. Those who store their cryptocurrencies in a self-custody wallet outside the exchange do not depend on MB resuming withdrawals.
One caveat regarding what the news does not cover: the cited statement mentions deposits and withdrawals. The report contains no information on whether buying and selling within the platform continue to function. Before assuming trading is available, check the app and the company’s official channels.
And the question almost everyone asks next: should I sell everything now? With withdrawals locked, there is not much you can move, and making decisions in the heat of a headline rarely helps. The recommended course of action in the meantime is unglamorous: save screenshots of your balance and transaction receipts, and wait for the next statement, which will indicate whether client funds are involved and how the resumption will proceed.
Why Does This Scare Weigh Heavier After Binance?
The sources do not link the two cases, and there is no indication that they are related. Even so, the timing is difficult for trust in crypto exchanges. In recent days, we examined how the Binance hack sent bitcoin tumbling and subsequently covered the resumption of withdrawals on that platform. Two security incidents at major exchanges in less than a week push investors to question where, ultimately, they should keep their coins.
There is also the regulatory backdrop, which was already on the agenda: Brazil’s central bank has been altering rules for these companies, as we detailed in our coverage of the new resolution for exchanges. Whether an incident like this affects the price of bitcoin is not addressed by the sources. Readers tracking the asset can find broader market context on our Bitcoin sector page.
What to Monitor Moving Forward
Three answers from the company will define the scale of the problem. The first is the official figure, to compare against the trackers’ estimates. The second is the nature of the loss: whether it came from the exchange’s reserves or client wallets, and how it intends to cover it. The third is the timeline for resuming withdrawals. Until all three are addressed, what exists is a precautionary warning, not a resolution.
Watch out for scams amid the confusion. When an exchange suspends withdrawals, it is common for fraudulent messages to appear offering to “release” balances or requesting passwords and verification codes. Only trust statements published on Mercado Bitcoin’s official channels, and never share your password or recovery phrase with anyone.
