Which do you think is best for a new project and why?
ICO - initial coin offering
IEO - initial Exchange offering
IDO - initial Dex offering
STO - Secority token offering
IEO is always the best for me because infinity I can be sure that they will not scam and will enter the exchange market in the future. In addition, IEO of top exchanges are always the best such as like binance, kucoin. So you should participate in all these IEO because the amount of risk is to low.
Note- I don't know if the same topic has been presented in the past and I'm creating the topic with my own ideas.
It depends on whose perspective you are looking at these options! For individual investors and traders in cryptocurrency, Initial Exchange offering(IEO), Initial Dex offering (IDO) are better! For institutional investors and those who must file taxes etc, Security token offerring is better! With STO, there must be a regulatory approval and doing the paper work will be easy for investors, there is also an assurance of security of your investment!
