50,000 Bitcoin Users Could Inherit Whatever This Browser Extension’s Next Owner Ships

A Bitcoin browser extension with 50,000 users is being offered for sale, and the real asset is not the code. It is the installed audience waiting for the next update.

CryptoSlate reports that Bitcoin Price Tracker is listed with a $55,650 asking price. The package includes the published extension, its source code, and 14 days of help transferring control to a buyer.

The extension displays BTC/USD pricing from Binance in a browser toolbar. Its store page identifies Extpose as the provider and shows 50,000 users, while the seller reports 37,100 installs over the year ending September 13.

The seller describes the product as pre-revenue and pitches possible financial-information services or partner offers to a buyer. The $55,650 figure is an asking price, not a disclosed sale price.

The offer also covers the codebase and a two-week handover. That turns the listing into more than a domain or branding sale because control of future releases is part of the package.

There is no evidence in the listing that a transaction has closed. There is also no evidence tying this extension or its seller to malware.

The listing documents an offer. It does not establish malicious conduct by the owner or a future buyer.

What the listing does establish is a price for something crypto users often overlook: control of future software updates.

A buyer of Bitcoin Price Tracker could control the updates sent to people who already installed it. Google's Chrome store lists 50,000 users.

The $55,650 asking price covers the extension, its code and 14 days of handover help.

The update channel is the valuable part.

When people install an extension, they are trusting more than one frozen piece of code. They are trusting a continuing update channel.

Whoever legitimately controls that channel can shape later versions delivered to an audience that made its original decision under a different owner.

Crypto users have an extra reason to care. Browser extensions can sit close to exchange sessions, wallet pages, transaction prompts, and the ordinary browsing habits that expose valuable information.

That does not mean an ownership transfer automatically bypasses browser permissions or security review. It means the familiar name and icon in a browser can remain while the party directing development changes.

Microsoft’s published Edge transfer process makes the gap especially clear. A new owner can gain control of an extension’s listing and updates before old owner details disappear from the public presentation.

Google directs organization-transfer requests through Chrome Web Store support and maintains policies against malware, phishing, and misuse of collected data.

The supply-chain risk is real, without accusing this seller.

Security firm Socket has documented separate cases in which attackers took over legitimate software distribution channels and pushed malicious releases. Its recent Ethersphere investigation involved a compromised release pipeline spanning npm and an Apple-notarized desktop application.

The product and mechanism were different. The common risk is a trusted delivery path changing hands or being compromised.

🚨 Attackers hijacked Ethersphere’s release pipeline to ship malware through npm & an Apple-notarized desktop app.

Our investigation links the attack to the earlier SleepyDuck malware campaign through the same Ethereum C2 contract and backdoor payloads.https://t.co/l4b4HUOVeL

In an earlier extension investigation summarized by CryptoSlate, Socket said attackers acquired five working extensions from their authors and later introduced malicious updates. The original products still performed their advertised jobs, which made surface-level familiarity a weak safety signal.

The practical response is routine maintenance, not panic. Crypto investors should periodically review installed extensions and remove tools they no longer need.

Recheck permissions after updates, and pay attention when ownership or publisher details change.

Bitcoin remains the largest crypto asset by market capitalization. A ready-made audience of 50,000 Bitcoin-focused browser users is commercially attractive, and control of their update channel deserves the same scrutiny as the software itself.
