Yes, it actually started with Initial coin offering(ICO) and things went well at that begining before it was characterized with scam and fake projects. The ICOs was fair in my opinion because it has produced many good projects that will are enjoying, at least, some top ten coins on difference exchanges were successful during the ICOs.
Unfortunately, the ICOs dwindled when scammers ravaged the system and currupted it.
The lack of trust from big investors, participants on the ICOs gave birth to the Initail exchange offering (IEO). I think the IEO method is currently doing great in my opinion.
Now, we are currently experiencing the Initial Dex offering, a new method of coin sales not too familiar among the a large number of the crypto communities globally. Do you think IDOs will make any difference? Your thoughts.
