The $BRIAN token, a memecoin inspired by Coinbase CEO Brian Armstrong, plummeted about 86% within 24 hours after Armstrong changed his X profile picture away from the token's artwork to a CryptoPunk image. This sudden price movement illustrates how closely Base's market responds to social cues from its most prominent supporter.

Data from DexScreener shows the $BRIAN token's market capitalization dropped to roughly $1.5 million following Armstrong's avatar switch. Trading volume reached approximately $13.2 million across nearly 30 Uniswap pools during the same period, with total liquidity at around $561,000. The main liquidity pool recorded nearly 15,000 buys and over 11,000 sells over 24 hours. The token began trading on July 14.

Armstrong initially set the stage on July 16 by updating his X avatar to the "Coinbase Man" artwork linked to the memecoin and tweeted "New profile photo who dis" at 7:52 p.m. ET. The post garnered about 1.6 million views, sparking a sharp rise in trading as investors interpreted the change as implicit support.

The rally ended quickly after Armstrong switched his avatar to a CryptoPunk NFT, an iconic pixel-art series associated with the 2021 NFT surge. The CryptoPunk image displays the 3D Glasses trait, and Armstrong acquired it recently, replacing the previous meme-based avatar. This shift caused retail traders to exit the $BRIAN token, leaving late participants with losses and concentrating gains among early buyers.

Armstrong's public wallet, linked to the ENS name barmstrong.eth, still holds some $BRIAN tokens, though he has denied any affiliation with the memecoin and did not create it. The token operates under a contract starting with 0xB2, aligning with Base's B20 token standard.

Base is a Layer 2 network incubated by Coinbase and among Ethereum's largest scaling solutions by activity. The project is currently reconsidering its strategic direction, moving away from creator and content tokens toward trading, payments, and AI agents. Recently, the Base App also underwent leadership changes. Despite these shifts, Armstrong's profile picture changes continue to significantly influence trading behavior on the chain.
