Irrespective of problems encountered by crypto enthusiasts like fake icos, scammers and delay. I think ICO plays an important rule in execution of sound projects. So Without ICO, most coins find it difficult to raise funds to execute their project. Without ICO, coins or projects will find it difficult to advertise their project, without ICO, projects will find it difficult to reach the right audience, Etc.therefore I believe in ICO because it enable me to research, analyst and evaluate the potentials of that project. Do you also believe in ICO?
ICO is just like the kick starter of a project, it act as the first funding to makes the project run.
Just as you said, without the necessary funding, a project will find a difficulty to make any improvement or just starting their work.
