For me, i don't support the ideology that ICOs are killing Bitcoin. Remember, through ICOs most people has got to know about cryptocurrency. Through the awareness creation made by ICOs, the entire crypto space has gone global. ICOs added a new sense of value to the crypto market.
ICO project is a free promotions for bitcoin,, and eth if the project using eth platform
because usually a new project will mentioned bitcoin, ethereum and others crypto as the payment methode,
so, i don't agree if somebody talk if ICOs are killing bitcoin
