if you really need a lot of funds then you need to do ICO/IEO but if you can get your own investors to fund the project that you are developing now then there is no need to do ICO/IEO
Yes, but for now if the project developer wants more funds for the project, the choice is through IEO on a good exchange bro, not through ICO because investors now no longer trust ICO since there are many scammers in ICO in the last two years.
it's really sad when discussing ICO the last 2 years, many investors are very disappointed with ico and now it is quite difficult to build investor confidence but it's a matter of trying and rebuilding trust in ico
