False X posts claiming 194-year-old tortoise Jonathan had died were used to promote an unaffiliated memecoin, whose market cap jumped 376% from $25,000 to $119,000. Joe Hollins, Jonathan’s real-life veterinarian, said he does not have an X account and called the crypto donation posts a con. The token later fell to $34,000 and stood at $74,000 at the time of writing.
