Predictions held that 2018 would be the year of the ICO. But it may be that the glory days of token sales are over, as backers are growing more skeptical.According to recent research by Ernst&Young, the climate for ICOs shifted in just a few months. The peak of 2017 came in the summer, when 90% of ICOs reached their rather ambitious targets for funding. The summer of 2017 was also the time for some of the largest, most prominent projects. But in November, after China banned ICOs, the inflow of funds had cooled. At the end of last year, just 40% of ICOs managed to get their intended funding.
