Coinbase CEO Brian Armstrong told traders not to treat his personal X activity as investment signals after changes to his profile picture triggered sharp moves in a Base meme coin.

Regarding the recent buzz around my profile picture changes and some feelings that the Base community isn’t being supported enough: I appreciate the feedback (even if tough to hear) and I realize you wouldn't take the time to respond unless you cared.

It seems I wasn't clear…

Armstrong said his posts and profile pictures should not be interpreted as endorsements or commitments to individual tokens. He added that he may not know when content he shares is connected to a coin or crypto project.

“Please don’t follow my personal X account for investment advice or signals around individual coins,” Armstrong said Monday while addressing criticism from members of the Base community.

The clarification followed volatility surrounding BRIAN, a community created meme coin based on a superhero style image of Armstrong.

Armstrong changed his profile picture to the image on July 16 and posted “New profile photo, who dis.” Traders interpreted the move as attention toward the token, pushing its valuation into the tens of millions of dollars.

The rally reversed after Armstrong replaced the image with a CryptoPunk. BRIAN fell roughly 86% over the following 24 hours to a market value of about $1.5 million, while traders generated approximately $13.2 million in volume across several Uniswap pools.

Armstrong said he supports people trading meme coins but warned that anyone using his account as a source of market signals was doing so against his wishes and at their own risk.

He also rejected criticism that Coinbase and Base leadership should promote individual ecosystem tokens.

Armstrong said Coinbase would not list every Base token because of compliance and regulatory restrictions. He added that neither he nor Base founder Jesse Pollak would “pump” community holdings or promote selected coins.

Instead, Armstrong said Base would support projects through builder programs, grants and investments from Coinbase Ventures and the Base Ecosystem Fund. Coinbase may also integrate promising Base protocols into its products to give them wider distribution.

The dispute comes as Base moves away from its previous focus on creator and content coins. Armstrong recently acknowledged that the strategy “didn’t work” and said the network had shifted its priorities toward trading, payments and AI agents.

Base had spent much of 2025 promoting creator tokens through integrations with Zora. Several high profile launches later collapsed, leading to criticism that the network had encouraged speculative activity without providing enough long term support for its wider ecosystem.

Armstrong said Base would continue supporting projects that create long term customer value but made clear that support would not include using his personal account to influence token prices.
