Sometimes i don't see it that promising specially when news and thread are talking about scam ICO, sometimes it is very hard to check and clearly say that it was not a scam. Fear of trusting some ico for it may be scam ICO.
Many scam ICOs in cryptomarket but not all ICOs scam. But its make investor afraid to join on good ICOs because bad experience. Sometimes its profitable when we joining on ICOs because we can get bonus as early adopter and early investor but we should research first before joining on ICO.
