Leading cryptocurrency exchange Coinbase has filed a federal lawsuit in California against Tobias Honscha, a resident of Isernhagen, Germany, alleging unauthorized use of the domain coinbase.de. According to Coinbase’s complaint, Honscha is engaging in cybersquatting and breaching affiliate terms to exploit the goodwill and trademark associated with the Coinbase brand.
The legal complaint accuses Honscha of using the domain to redirect visitors to an app focused on physical coin trading, as well as leveraging the Coinbase name to allegedly profit as an affiliate. Coinbase asserts that this use violates its affiliate agreement, which explicitly prohibits domains containing “Coinbase” or any spelling variations that may confuse users into believing they are interacting with the official Coinbase platform.
“Honscha violated the terms of the Affiliate Agreement by using the coinbase.de domain, which fully incorporates the COINBASE trademark and gives the impression that Honscha is one in the same with Coinbase,” the lawsuit states.
Alleged Pressure to Sell Domain at Inflated Price
Coinbase also alleges that Honscha attempted to pressure the company into buying the domain at a significantly inflated price. The exchange claims that Honscha warned of potential risks, including phishing attacks, identity document leaks, and the submission of sensitive data such as two-factor authentication codes if Coinbase refused to acquire the domain.
“This is a clear attempt to hold Coinbase hostage by threatening to offload it to a buyer who would weaponize it even more,” Coinbase’s filing noted.
Domain Used for Redirection and Email Service
After Coinbase requested the affiliate link be removed, the domain was reportedly redirected to a mobile app associated with trading physical coins. Furthermore, the lawsuit reveals that Honscha operated an email service using the @coinbase.de domain, which could deceive users into believing they were communicating with the official Coinbase support team.
“These mistaken emails have and will continue to occur,” Coinbase stated, adding that users often assume company-related domains are legitimate corporate sites.
At the time of reporting, the domain currently redirects to a coin collector discussion forum, where Honscha is listed as the “responsible person.” An email listed on the forum did not respond to inquiries for comment.
Coinbase Seeks Damages and Domain Transfer
Coinbase is asking the court to stop Honscha from using the domain, transfer it to Coinbase, and award damages for trademark infringement and breach of the affiliate agreement, including any commissions he may have received.
The complaint underscores the broader concern in the crypto industry over cybersquatting, where malicious actors exploit brand trust for personal gain or to scam unsuspecting users.
This case reinforces the importance of protecting brand identity in the digital age, especially in the fast-moving cryptocurrency sector.
