Esteban Bullrich can’t move his face the way he used to. ALS took that from him. And Binance’s facial recognition system couldn’t figure out who he was anymore.
The former Argentine senator—who ran the country’s education ministry from 2015 through 2017—got locked out of his account for five months straight. During that stretch, Bitcoin dropped from the $90,000 range all the way down to the $70,000s. His assets sat frozen the entire time. Bullrich announced his ALS diagnosis back in April 2021, and the disease has changed his appearance enough that Binance’s biometric system basically gave up on him.
Viral Post Forces Response
Bullrich took his frustration to social media, tagging Binance founder Changpeng Zhao and co-CEO Richard Teng directly. That’s when things moved. Teng saw the post after it went viral and jumped in personally. He said Binance would work on fixing the accessibility gaps for users dealing with similar challenges. But Bullrich wasn’t happy with just an apology. He pointed out that Binance didn’t offer any backup authentication method for people whose faces change because of disease or disability.
The whole thing revealed a pretty big blind spot. Binance Argentina admitted it was an accessibility failure after the post blew up online. They said they’d make improvements. No timeline, though. No specifics on what those improvements would look like or when users could expect them.
System Built Without Edge Cases
Binance rolled out biometric authentication back in 2022. By December 2025, the exchange had crossed 300 million registered users. That’s a massive user base, and somewhere in there are people with ALS, facial injuries, burn scars, and other conditions that change how they look. The system didn’t account for them.
ALS attacks muscle control. Facial muscles included. Over time, the disease changes a person’s appearance in ways that facial recognition software can’t always track. Bullrich’s case made that clear. The technology worked fine when he first set it up, but as his condition progressed, the system stopped recognizing him. And there was no Plan B.
Binance’s standard support process didn’t solve the problem either. Bullrich stayed locked out for months, watching Bitcoin’s price fall, unable to access his holdings. It took public pressure and a viral social media post to get the company’s attention. That suggests the normal customer support channels aren’t equipped to handle complex accessibility issues without someone high up stepping in.
The exchange’s Argentine team reached out after Teng got involved, trying to fix Bullrich’s situation and promising to prevent similar cases going forward. But the damage was done. Five months is a long time in crypto. Prices moved, opportunities vanished, and Bullrich couldn’t do anything about it.
Other platforms face similar challenges. Biometric systems are convenient for most users, but they create barriers for people whose physical characteristics change over time. Age, illness, injury—all of these can make facial recognition unreliable. Financial platforms need backup options, especially when they’re holding someone’s money hostage.
Bullrich’s experience sparked conversation about how accessible digital finance platforms really are for people with disabilities. The lack of an alternative ID method for users who can’t use facial recognition points to a gap in how these systems get designed. Companies build for the majority and forget about edge cases until someone gets hurt.
The speed of Binance’s response once the issue went public was notable. Teng moved fast after seeing the post. But that raises questions too. Why did it take a viral moment to get action? Why couldn’t the standard support process handle this? If you’re running a platform with 300 million users, some of them are going to have accessibility needs that don’t fit the default setup.
There’s no word yet on when Binance will roll out a permanent fix. The company said it would address accessibility gaps, but didn’t commit to a timeline or describe what the solution would look like. That leaves users like Bullrich—and others dealing with conditions that affect their appearance—in a kind of limbo. They can use the platform now, maybe, but what happens if the system locks them out again?
The incident highlighted how much work remains in making crypto platforms truly inclusive. Biometric authentication is popular because it’s fast and feels secure. But it’s not foolproof, and it’s definitely not accessible for everyone. Digital finance companies need to think harder about the diverse needs of their user base and build systems that work for people whose circumstances don’t fit the standard profile.
Bullrich’s case also drew attention to the broader issue of customer support responsiveness at major exchanges. Despite Binance’s size and resources, resolving this problem required public pressure and executive intervention. That pattern suggests standard support channels might not be equipped to handle complex situations without someone at the top getting involved. For users without a public platform or social media following, that’s a problem.
As of now, Binance hasn’t provided details on what changes it plans to make or when those changes will take effect. The exchange admitted the accessibility failure and promised improvements, but the specifics remain unclear. Users with disabilities who rely on alternative authentication methods are still waiting to see what Binance will do differently.
