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.
