Binance Investigates Potential $5.7 Billion Hack as Tether and Circle Freeze Billions in Crypto

A recording from Daily Crypto News's live video

Daily Crypto News | Breaking News | October 29, 2026

Good evening, everybody. My name is Matt, and welcome to an emergency edition of Daily Crypto News.

I don’t do many live streams anymore, but when reports start circulating that Binance, the world’s largest cryptocurrency exchange, may have just suffered one of the biggest cryptocurrency hacks in history, I think that’s a pretty good reason to jump online.

And the numbers are changing incredibly quickly.

When I first started looking into this, reports suggested approximately $2.5 billion had moved out of Binance wallets.

Then we were talking about $2.8 billion.

Then $5.6 billion.

And by the end of the live stream, some estimates were approaching $5.7 billion.

Those are estimates of suspicious transfers, not a final confirmed loss. Binance is investigating, and we still don’t know exactly how much was stolen, how the attackers gained access, or how much can ultimately be recovered.

But even at the lower end of the estimates, we’re talking about an extraordinary security incident.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Billions Move Out of Binance Hot Wallets

The first major warning signs appeared Thursday afternoon, when blockchain investigators noticed enormous transfers out of wallets associated with Binance.

The activity was reported around 4:30 p.m. Eastern.

Some of the initial transactions involved Ethereum and stablecoins, including Tether’s USDT and Circle’s USDC.

As investigators examined additional addresses and blockchain networks, their estimates of the total amount involved increased.

Decrypt reported approximately $5.57 billion in suspicious transfers across Bitcoin, Ethereum, and Tron. Other investigators reported smaller totals, depending on the wallets and transactions they included.

And that’s why I’m being careful about calling this a confirmed $5.7 billion theft.

We know there have been enormous suspicious movements. We know Binance is investigating. But we don’t yet have a final accounting from the exchange.

If the highest estimates are confirmed as stolen funds, this could surpass the roughly $1.4 billion Bybit breach in 2025 and become the largest cryptocurrency hack on record.

Now, some people have asked me why Binance would have billions of dollars sitting in wallets that could potentially be compromised.

Remember, Binance handles an enormous amount of trading activity.

During the live stream, I was looking at figures suggesting approximately $11 billion in daily trading volume.

That doesn’t mean the exchange needs $11 billion sitting in one hot wallet. But a business processing that much trading and withdrawal activity needs substantial liquidity available.

And that creates an important security challenge.

A hot wallet is connected to systems that can authorize transactions relatively quickly. That makes it useful for everyday exchange operations, but it also creates more potential attack surfaces than properly secured offline storage.

The challenge is balancing liquidity, convenience, and security.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Tether and Circle Freeze More Than $2 Billion in Stablecoins

Here’s one of the most important developments in the entire story.

Tether and Circle moved quickly to freeze stablecoins associated with the suspicious transactions.

Initially, Changpeng Zhao, better known as CZ, thanked the companies for freezing approximately $971 million in USDT and $823 million in USDC.

Then the numbers increased.

Tether CEO Paolo Ardoino said his company had frozen more than $1.567 billion in USDT.

Reuters subsequently reported that Tether and Circle had frozen more than $2.38 billion combined, with Ripple also reportedly freezing approximately $200 million.

That’s an enormous amount of cryptocurrency that the suspected attackers may no longer be able to move.

But there’s an important distinction here.

Frozen does not mean recovered.

Tether and Circle can restrict transfers of their centrally issued tokens under certain circumstances. That can prevent the holders of those tokens from moving them while investigators determine what happened.

It doesn’t automatically mean the money has already been returned to Binance or credited back to customers.

Bitcoin works differently.

There isn’t a central company that can simply freeze an ordinary Bitcoin address because somebody reports a theft.

And while Ethereum’s native ETH can sometimes be tracked through the blockchain, it doesn’t have the same issuer-controlled freezing mechanism as USDT or USDC.

That makes the composition of the suspicious transfers incredibly important.

How much was in stablecoins? How much was native cryptocurrency? How much was moved into other addresses or exchanged for different assets?

Those questions will help determine how much can realistically be recovered.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

CZ Says User Funds Are Safe, but He’s No Longer Running Binance

CZ responded publicly as the news spread.

He said the activity appeared to be a hack, thanked Tether and Circle for acting quickly, and stated that user funds were safe.

But he also made something very clear.

He no longer manages Binance.com.

As a shareholder, he said he expects all user funds to be fully covered.

That’s encouraging if you’re a Binance customer.

But an expectation from a shareholder isn’t the same thing as a finalized reimbursement plan from the company.

Binance itself said it was investigating a potential security issue and that customer funds were safe.

The company also reportedly suspended withdrawals on multiple networks as a precaution.

Now, the big question is how Binance would absorb a loss of this magnitude if the largest estimates are confirmed.

Binance has an emergency protection fund known as SAFU, or the Secure Asset Fund for Users.

The company previously used that fund to cover losses following its 2019 security breach.

But I haven’t confirmed how much was available in the fund at the time of this incident, and we don’t yet know the ultimate amount Binance might need to cover.

We’re talking about potentially billions of dollars.

Even for the world’s largest exchange, that’s serious money.

And I think customers deserve clear answers about what assets were affected, how the incident occurred, and exactly how their balances will be protected.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Was Artificial Intelligence Involved in the Binance Attack?

This is the part of the story that really concerns me.

We’ve spent the past couple of weeks discussing how artificial intelligence is changing cybersecurity.

AI tools can examine enormous amounts of code, identify unusual behavior, and help researchers discover vulnerabilities that might previously have taken much longer to find.

That’s useful when legitimate security researchers find the weaknesses first.

It’s potentially dangerous when attackers use the same tools.

We’ve already discussed vulnerabilities involving Bitcoin Core, Electrum wallet software, and other cryptocurrency infrastructure.

And now, with Binance, investigators are trying to understand how such a large amount of cryptocurrency could have been moved.

One theory circulating during the live stream involved Ethereum’s EIP-7702 functionality, which allows certain accounts to delegate execution capabilities to smart-contract code.

Could an attacker have exploited a problem involving delegated execution, account permissions, or exchange infrastructure?

Possibly.

But we do not have evidence establishing that EIP-7702 or AI caused this incident.

And I don’t want to present a theory as a confirmed explanation.

The vulnerability could involve compromised credentials, software, internal systems, transaction authorization, or some other mechanism that hasn’t yet been identified publicly.

We simply don’t know.

My broader concern is that AI-assisted attacks could become more frequent as increasingly capable tools become available.

If AI can help legitimate researchers discover security weaknesses, it can potentially help malicious actors look for them too.

But that doesn’t mean every major cryptocurrency hack is automatically an AI attack.

We need the investigation before we can make that determination.

Bitcoin Falls Below $79,000 as Binance’s BNB Token Takes a Hit

The cryptocurrency market reacted quickly.

During the live stream, Bitcoin was trading around $78,000, while Ethereum was approximately $2,270.

BNB, the token associated with the Binance ecosystem, was taking a larger hit, down approximately 7% at one point.

And here’s what surprised me.

Considering the possibility that billions of dollars had just been stolen from the world’s largest cryptocurrency exchange, the broader market reaction wasn’t nearly as catastrophic as I might have expected.

That’s not to say the losses were insignificant.

Bitcoin was down. Ethereum was down. BNB was getting hit harder.

But the entire cryptocurrency market wasn’t collapsing.

Now, that could change as additional details emerge.

If Binance announces that customer withdrawals will remain restricted, that losses are greater than expected, or that reimbursement will take time, investors could react differently.

On the other hand, if the exchange provides credible evidence that customer balances are fully protected and much of the affected cryptocurrency has been secured, confidence could improve.

We’re watching a developing situation.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Coinbase Offers Support as the Industry Watches Binance

Coinbase also issued a public statement during the incident.

The company said its own platform remained safe and secure, that it was monitoring the Binance situation, and that it had contacted Binance to offer assistance.

That’s good to see.

But it also raises a bigger question.

What happens when a cryptocurrency exchange suffers a massive security breach?

Do customers get reimbursed automatically?

Is there an emergency fund?

How much capital has the company reserved for an event like this?

And how much responsibility does an exchange have when the security failure occurs within its own infrastructure?

These are questions every cryptocurrency investor should be asking.

Ordinary cryptocurrency holdings at an exchange are not automatically protected by FDIC insurance simply because the exchange operates in the United States.

Coverage depends on the asset, the account arrangement, applicable law, and the company’s contractual obligations.

That’s why it’s important to understand what protections your exchange actually offers before something goes wrong.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

My Take

Here’s what I’m watching tonight.

First, I want a confirmed accounting from Binance.

Not estimates from social media. Not guesses about wallet movements.

I want to know exactly how much cryptocurrency was compromised, how much has been frozen, and how much remains under the suspected attackers’ control.

Second, I want to know how Binance plans to protect customers.

CZ says he expects user funds to be covered. Binance says customer funds are safe.

Now the company needs to provide the evidence and details that support those statements.

Third, I want to know how the attack happened.

If this turns out to involve AI-assisted vulnerability discovery, that’s going to raise serious questions about the future of cryptocurrency security.

But until investigators establish that connection, I’m not going to pretend we know the answer.

And finally, I want to see how the rest of the cryptocurrency industry responds.

We’re talking about the world’s largest exchange. If a security incident of this magnitude can happen there, every other exchange should be reviewing its systems, wallet permissions, and emergency procedures.

This is going to be a developing story, and I expect the numbers and details to continue changing.

I’ll keep following it as we learn more.

Thanks to everybody who jumped into the emergency live stream tonight.

My name is Matt, and I’ll see you on Daily Crypto News.

Happy HODLing
