The decline in market prices that occurred throughout 2018 did have a very large negative impact. Many ICO projects failed due to lack of funds. Funds collected are not enough to run the ICO project. And it's better to invest in existing coins and the top 10 coins, I think that can give you an advantage.
Many ICO projects failed and lacked the trust of investors as the main reason why ICO could hardly survive in 2018 but this year things got worse when the IEO was first released and it makes all ICO projects a landfill. I think the launch of IEO projects makes investors feel safer because we can secure assets and can trade more easily. In my opinion this will be a new beginning for investment and we should look for major IEO projects to have the opportunity to participate.
