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.
It seems to me that interest in the world of CryptoWorld was influenced by the price of BTC, when it began to grow rapidly, and not the numerous ICOs that we see now.
