Anyway, I do have a question, I noticed that there some ICOs who didn't meet the softcap and of course no tokens will be delivered to the participants. Will this be considered as scam?
Well you can say that. But it's not entirely a scam if the team really had the vision for it but the people and the idea didn't really connect. Also, ICO stands for initial coin offer and you can think of it as a pre-sale for tokens that are possibly have higher values in the future. Therefore, you can consider it as a failed ico but not scam.
