Still waiting when ICO come back and give more profit for investor like happen last three years where many investors get much profit from ICO investment, I think almost ICO last three years always worth and have higher price after trading, I think with gas price still highest need review for investor to buy ICO project because they will take care how to invest with project without pay higher fees and process become faster.
An ICO like three years ago will never exist again at any time, because now there are new developments that are better than the ICO project, so investors will try to look at new things instead of the old ones, and for the problem of Gas costs I think it is only complained about by small investors, while big investors don't really complain about this.
I actually think so too, the good project already being snatched by exchanges and also offers instant listing while taking some portion of the tokens and become middlemen, it's good for the investor and the project but then again it's kinda lengthy process compared to ICO.
However, as long as IEO still exist only small amount of good project gonna do ICO so it's not gonna be the ICO season we once knew instead a stable market of IEO that's more secured and reviewed thorougly to reduce scams.
