Woofun AI reports that the Base Chain meme token Brain, which utilizes the B20 standard from the Beryl upgrade, experienced a severe valuation correction. The token's market capitalization fell by more than 93% within 24 hours, dropping from a peak above $35 million to $1.4 million, accompanied by $21 million in trading volume. The price movement correlates with Coinbase CEO Brian Armstrong updating his Twitter avatar to an X icon resembling the token's logo, which initially triggered speculation and volume, followed by intense selling pressure as the avatar was changed again.
