Or do you prefer projects that just do a ICO without any Pre ICO.
I would like to know your opinion as investors which method you prefer and which makes a better impression at you.
ICO projects are growing very much from 2017, until 2018 ICO has decreased against investor interest. But in my opinion now, Pre-ICO or ICO is less effective in raising funds, because the trend of investors is now more confident in the development of the IEO.
If you are a developer, you can do all three, namely, Pre-ICO, ICO, then IEO, now this IEO to win the trust of investors.
