🚨 JUST IN: MERCADO BITCOIN REOPENS — BUT YOU CAN'T TOUCH YOUR MONEY. 👀

Read-only accounts reopened today, a week after the $49M hack.
Balances frozen at Nov 2. No withdrawals, no date.
The exchange replaces every stolen coin from its own funds.
$15M+ frozen. $33M still with the attacker.
$BTC — would you trust them with your coins again? #MercadoBitcoin #CryptoHack #Brazil #cryptonewstoday

Mercado Bitcoin has restored read-only access; withdrawal timing remains undetermined. Approximately $49 million was lost, but officials say most assets were unaffected and some funds have been frozen. Security analysis indicates this involved ordinary transfers, not a smart contract vulnerability; how wallet permissions were compromised remains unclear. For security, users must verify their information before withdrawing. The platform plans to enable Pix first and limit withdrawals to users’ own accounts. #MercadoBitcoin #加密安全 #HackerAttack

Mercado Bitcoin took the first step toward resuming operations.

The platform enabled access to balances from before the hack.

They’re doing this through a gradual rollout for users.

For now, there’s no confirmed date for withdrawals.

It’s a relief to see the numbers again, but uncertainty about the money remains.

What do you think of this reopening process?

Mercado Bitcoin has restored read-only access; withdrawal timing is still unknown. Approximately $49 million was stolen earlier. Officials say most assets are safe, and some funds have been frozen. Security analysis confirmed that the transfers were ordinary transactions, not the result of a contract vulnerability; how wallet permissions were exposed remains unclear. Users must confirm their information before they can withdraw. The platform plans to enable Pix first, limited to users’ own accounts. #MercadoBitcoin #加密安全 #Cyberattack

Brazil’s largest exchange, Mercado Bitcoin, has finally reopened—but only a crack: hackers made off with about $49 million on November 2, and a week later, its 4.8 million users can finally log back in and check their balances today—just look, no transactions. Trading, deposits, withdrawals, and transfers are all suspended. The company won’t even give a timeline for withdrawals, saying only that services will be restored in phases and that its own funds will cover the losses. Seeing your money but being unable to withdraw it is more agonizing than not seeing it at all. Do you think this “read-only revival” means they’re really working to fix things, or just stalling while they buy back funds to plug the hole? What do you think?

Mercado Bitcoin has restored read-only access; the timing of withdrawals is still undetermined. Losses are estimated at about $49 million. Officials confirmed that most assets are safe and some funds have been frozen. Security analysis indicates that this was a regular transfer, not a smart contract vulnerability; how the wallet permissions were compromised remains unclear.

🚨 Mercado Bitcoin, one of Brazil’s largest exchanges, was hacked a week ago. Tomorrow, it will only open in “read-only mode”—you can check your balance, but you can’t withdraw!

📌 What happened (according to Tech Insider):
• 11/2: The platform suspended deposits and withdrawals, citing a security incident
• Analysts found that 36,042 ETH deposit addresses were emptied within 4.5 hours, at an average rate of about 134 per minute
• Estimated losses: $40–46 million; not officially confirmed
• Tether froze more than 4.5 million USDT
• The exchange says users suffered no losses and has promised compensation

⚠️ Key points:
1️⃣ On 11/9, users can only view balances and statements. There’s no restart date for trading, deposits, withdrawals, or transfers
2️⃣ The numbers on your screen ≠ your money is still there. There’s currently no independent proof of reserves
3️⃣ Deposit addresses were swept in bulk, suggesting a possible problem with the key/signature system. The exchange hasn’t announced the cause yet
4️⃣ Stablecoins can be frozen, but assets like $ETH can’t be “called to a halt” by anyone

💡 A reminder for us: Don’t leave coins you aren’t trading on an exchange long-term; beware of fake support agents trying to steal your recovery phrase during a freeze; after withdrawals resume, test with a small amount first.

BTC is currently around $75.7K, and the Fear & Greed Index is 28 (Fear). With a major exchange hacked and a smaller one shut down, would you still keep most of your assets on exchanges? Share your thoughts in the comments 👇

Personal opinion only; not investment advice

Mercado Bitcoin reported containment of a hack only for the attack to continue hours later. This suggests a critical failure in exchange security protocols and incident response.

#MercadoBitcoin #ExchangeHack ‎

I've been waiting for one line from Mercado Bitcoin since Monday: a date. Now there's one — with a catch.

The Brazilian exchange says account access returns in phases starting Monday, November 9. First step is view-only: balances, statements, holdings and investments through its website. Transfers, withdrawals and trading come only in later phases, after independent security testing.

That matters because the November 2 post left the timeline blank. Mercado Bitcoin also says it will use company funds to replenish affected assets, and that more than $15 million in stolen funds has already been frozen with industry help — up from about $11 million blocked in its November 2 update. Analyst estimates still put the theft above $46 million, which the exchange has not confirmed as a final total.

So Monday restores visibility, not function. $BTC near $80,543 (+3.7%/24h) and $ETH near $2,426 (+6.3%) on Binance spot is context, not a reaction I'm claiming for this update.

Would view-only access reassure you, or would you wait until withdrawals actually reopen? NFA, DYOR.

Mercado Bitcoin Hack: Official Statements Diverge from On-Chain Data, Putting $USDC to the Test of Trust

The security narrative in crypto markets has come under pressure once again. After Brazil’s largest cryptocurrency exchange, Mercado Bitcoin, was hacked, the company quickly issued a statement saying the attack had been contained. However, third-party on-chain tracking data revealed a more complex flow of funds, creating a clear discrepancy between the two accounts.

According to Decrypt, the latest forensic analysis tracked $48.6 million across 11 blockchains and found that thousands of customer deposit addresses were involved. This stands in stark contrast to Mercado Bitcoin’s claim that the situation was “under control,” suggesting that hackers may have laundered some of the funds through mixers and other means, raising the risk of short-term selling pressure.

The incident matters because Mercado Bitcoin is not only a major player in Brazil’s market but also one of the main issuers of $USDC . The security breach directly undermines users’ confidence in stablecoin custody and could trigger liquidity strain and a crisis of trust. If the exchange cannot fully reimburse users for their losses, market sentiment may deteriorate further.

Technically, the hackers dispersed the funds across multiple chains, making them more difficult to track and recover. On-chain data shows that the funds moved through a fragmented and complex web of transactions, which traditional tracking methods may struggle to cover completely. Market participants should remain vigilant and monitor the funds’ movements.

How might the market react? In the short term, $USDC could face price volatility, and investor confidence may take a hit. If the incident is mishandled, rebuilding trust over the long term will take more time. Conversely, if Mercado Bitcoin handles compensation transparently and efficiently, market sentiment may gradually recover.

The opposing factors and risks include the possibility that the hackers have thoroughly laundered the funds, making recovery extremely difficult. In addition, if similar security incidents occur at other exchanges, panic could spread through the market and affect a wider range of crypto assets.

What should we watch next? Key things to monitor include Mercado Bitcoin’s progress on compensation, the funds’ ultimate destination on-chain, and changes in $USDC market liquidity. From a trading perspective, it is more important to wait for confirmation from the market than to rush into action.

I will continue to follow developments and provide updates if there are any significant developments.

A new Bitquery report sheds light on the hack of Brazil’s Mercado Bitcoin: even after officials said the situation was “under control,” the attacker continued draining customer deposit addresses for about four hours.

The timeline stands out—the situation was declared under control at 12:56 UTC on November 2, but about 36,000 Ethereum deposit addresses were drained from 12:27 to 16:56. Bitquery tracked about $48.6 million across 10 chains, more than the roughly $40 million disclosed earlier. The same attacker address was also linked to a suspected BitMart wallet. BitMart’s founder confirmed it was hacked on the same day and said the same group was initially suspected; that portion amounted to about $391,000.

The platform has pledged to cover losses with its own funds, while the industry has frozen more than about $15 million. The website is expected to first reopen for read-only balance viewing on November 9; no date has been set for deposits, withdrawals, or trading. The hot wallet and deposit-address permissions issue has once again served as a warning.#加密安全 #MercadoBitcoin

Mercado Bitcoin hack continues after exchange says it contained the breach; BitMart also implicated

Mercado Bitcoin has pledged to cover the $46 million loss out of its own pocket—a kind of “safety net” that’s practically unheard of in crypto. Accounts were restored on Monday, but can they really plug this huge hole? Let’s hope they’re not treating users like bagholders. Best to wait and see.

Mercado Bitcoin Announces Restart Plan: Latin American Crypto Liquidity Faces a New Test

Latin America’s crypto market recently saw a major development: the region’s largest exchange, Mercado Bitcoin, announced that it will begin a phased restart on Monday. The decision comes after the platform suffered a security incident and suspended services, marking an important step in its efforts to restore user trust and resume operations. According to Cointelegraph, during the initial phase of the restart, customers will only be able to view their asset holdings. Withdrawals and trading will remain suspended until the security review is complete.

The restart will proceed in phases, with the aim of reducing systemic risk and gradually verifying system stability. For Latin American users who have long relied on the platform to manage their assets, this change means liquidity restrictions may gradually ease. At the same time, it highlights the vulnerabilities in an exchange’s security architecture when dealing with sudden attacks. The phased restart is not only a technical recovery measure, but also a stress test of market confidence.

From the perspective of capital flows and the broader economy, Mercado Bitcoin is one of the most influential crypto trading platforms in Latin America, and its operational status directly affects the region’s liquidity supply. The current suspension of withdrawals and trading may leave some users’ assets inaccessible, in turn affecting short-term market activity. If the restart proceeds smoothly, frozen liquidity is expected to be released gradually, injecting fresh momentum into the market.

However, this process is not without risks. The ongoing effects of the security incident, potential changes in the regulatory environment, and the extent to which user confidence recovers will all determine whether the restart can generate a genuinely positive market response. The platform has not yet announced a specific timeline or detailed updates on technical repairs, so market participants should continue to monitor the situation cautiously.

The focus now will be on how each phase of the restart is carried out, the progress of restoring users’ access to their assets, and the response from Latin American regulators. If the platform proceeds on schedule and provides transparent updates, it may help stabilize regional market sentiment. Conversely, delays or technical failures could trigger further liquidity constraints and fluctuations in confidence.

【Exchange said “the situation is under control,” but hackers kept stealing for another 4 hours! Brazil’s Mercado Bitcoin hack losses rise to $48.6 million】
On-chain tracking shows that approximately $48.6 million was stolen from Brazilian exchange Mercado Bitcoin across 10 blockchains on November 2. The hackers not only drained the hot wallets but were also able to directly access users’ deposit addresses, emptying 36,042 addresses on Ethereum alone. They continued transferring funds for about 4 hours after the exchange announced that “the attack was under control.” Stablecoin issuers have so far frozen only about $11.8 million; most of the rest remains in the hackers’ wallets. On November 3 and 4, the hackers sold about $11.9 million worth of tokens for ETH. Users who send funds to old deposit addresses may still have them stolen directly.

Mercado Bitcoin finally gave a date: next Monday (November 9), account access will be restored first; withdrawals and trading will have to wait

First, a note on timing to avoid confusion: this is not news that just broke in the past hour. It’s an update the exchange gave Cointelegraph at around 07:20 this morning (Beijing time). It missed the morning news cycle, so this is a follow-up—but the content is a substantive new development and worth covering on its own.

The facts: Mercado Bitcoin says it will begin a phased restoration next Monday. In the first phase, users will only be able to access their accounts on the website to view balances, statements, holdings, and investment records. Transfers, withdrawals, and trading will remain unavailable until each is separately cleared by independent security testing. The company’s loss coverage policy hasn’t changed: it will use its own funds to make up the losses, and its trading desk is preparing buybacks at home and abroad. The frozen-asset total has moved up another notch: more than $15 million has been frozen (the previous official figure was about $12.9 million). Note that these are two different ledgers: the officially reported affected assets total about $36.3 million, while analytics firms estimate that more than $46 million was stolen. One is the official figure; the other is a tracking estimate.

My take: moving from “we’ll see when the conditions are met” to “account access opens next Monday” is the first time the recovery effort has taken shape—but having a shape doesn’t mean the money is back. Being able to view your balance ≠ being able to withdraw; frozen ≠ returned. The real test is when the second phase begins after next Monday, and what tests must be passed before services reopen. In an earlier post at 04:38, I noted that the frozen share had risen from about 29% to about 36%. Based on $15 million out of $36.3 million, it’s now about 41%. The trend is still toward recovering the funds, but where the bulk of the remaining amount went and when the buybacks will happen are still unknown.

A quick market note (checked against two sources at 09:39): $BTC was about $80,580, up around 4.65% over 24 hours, and still holding above $80,000. The overnight high of $81,196 hasn’t been broken. Rather than saying the market has forgotten the security incident, it seems more like it’s stabilizing first and asking questions later.

Risk warning: The exchange’s restoration timeline could be delayed at any time depending on test results. Don’t interpret “account access next Monday” as “withdrawals available next Monday.” For funds in transit and buyback progress, rely on the next official statement; analytics firms’ estimates are not definitive.

What do you think: is opening account access first and withdrawals later the responsible approach, or just a stalling tactic? #MercadoBitcoin #交易所安全 #BTC

Brazil’s largest exchange was hacked for over $46 million. Its recovery timeline is finally set: read-only access returns first on November 9

Here’s what we know: Since the November 2 hack, Mercado Bitcoin has kept deposits, withdrawals, and trading suspended.
On Monday, November 9, website access will be restored for viewing only, allowing users to check their balances, statements, and holdings.
Withdrawals, transfers, and trading will resume later, with each service cleared only after passing independent security testing.

The information comes from a November 4 report by Cointelegraph, which confirmed the timeline directly with the exchange.
The exchange has pledged to cover affected assets with its own funds, and over $15 million in stolen funds has already been frozen.

My take: This isn’t “business as usual”—it’s a first step to let users see for themselves that their account balances are still there. It won’t truly be back until withdrawals work.

What I’m doing: I’m treating this as a recovery roadmap, not a bullish signal. If even read-only access isn’t up by November 9, this “phased” approach deserves some skepticism.

Do you think read-only access first is a prudent move, or has taking seven days just to let users view their accounts already been too slow?
