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.
ICOs doesn't contribute a lot of impact to the crypto market but BCH does it. You should take a look on a lot of news that the BCH fork and battle was creating a lot of uncertainties in the cryptocurrency. you should think again about that, try to do your own research dude and it's really important.
