After 2-3 years of good times for crypto start up projects I do not think that future is bright for new projects. Because come with a new idea is pretty hard since we have thousands of diffrent crypto projects.
In my opinion IEO will be really good in the future because many people are now trusting it and investing a huge amount of money. And If many people will continue to support IEO i am really sure that it will lasts for many years.
