In this case, I agree with the overall sentiment. I don’t think these companies are actually “dying” though, but rather they were probably created as get rich quick schemes, so they took the millions of dollars they raised and then sailed off to some island somewhere.
From the report
> We use intensity of tweets from the cryptocurrency official Twitter account after the ICO to estimate that the survival rate for startups after 120 days (from the end of the ICO) is only 44.2%, assuming that all firms inactive on Twitter in the fifth month did not survive.
Not sure how I feel about that methodology, but probably many of these companies never planned to actually issue a product in the first place so it may very well be accurate.
