Technology investor Jason Calacanis called meme coins a "giant scam" and said he has no involvement with projects using his name or implying his endorsement. He said he would never privately ask followers to buy, sell or trade financial assets, particularly through social media or direct messages. Calacanis identified Bitcoin and Bittensor's TAO as cryptocurrencies he sometimes discusses publicly, while maintaining a skeptical view of Bitcoin's utility, adoption and market direction. The meme-coin sector has a combined market capitalization of about $35.9 billion and roughly $3.55 billion in 24-hour trading volume, according to CoinGecko data cited in the report. His warning comes amid repeated cases involving hacked or impersonated public figures, including Robinhood CEO Vlad Tenev, trader Keith Gill and crypto commentator Ansem. Calacanis said any meme coins sent to accounts under his control would be directed to a good cause, but he did not identify a specific token or say that his account had been compromised.
