A Boston College research paper entitled Digital Tulips finds that fewer than half of these projects survive more than 120 days after the completion of their sales of tokens to the public.
The researchers arrived at this conclusion by examining the official Twitter accounts of the crypto-currencies. They found only 44.2% of them were still tweeting after that four-month period and concluded that the rest of the ICOs had died.
Mind you, the study also finds that the ICO gold rush is continuing, with $12bn raised from more than 4,000 ICOs since January 2017 - and those investors who got in and out quickly made big profits.
