This paper studies the survival of cryptocurrencies and their association with the social media attention they receive. The death of a cryptocurrency is defined based on the discontinuation of trading activities and modeled using Kaplan – Meier Survivor Function and the Cox survival regressions. Using data collected from coinmarketcap.com and bitcointalk.org, we find that social media attention is a very relevant influencer for the death hazard. Specifically, the death hazard of a cryptocurrency is estimated to increase by 0.5% - 1% for each additional trading day without any social media mention. We also find that high-quality social media mentions are more effective in reducing the death hazard. The theoretical and practical implications of the findings are discussed in the paper.
