The massive drop of value of many ICO coins and rising even though slow of STO COIN is not connected to lack of interest of people but I will say it is government play and trick to control the CRYPTOcurrency.
Ok now mostly the Asia countries like Korea and China and USA is supporting the STO coin than ICO (I don't know the reasons but I think it is because the have power over them) Ico's blockchain s and Community is facing alot of security issues, hacking of the ICO blockchain and Community, aiming to reduce the users of ICO coins. I think the Government is behind it. Ok now, have you thought of this that any STO coin is equivalent to US DOLLAR value and you hardly see any STO higher than US dollar (prove me wrong if not true ).
Thanks for this lovely post
