Bitcoin is at the core of all altcoins and should be respected, coins and their developers should avoid trying to harm Bitcoin with their false narratives and lies because if you harm Bitcoin you just harm the value of your own coin and all other altcoins. You also weaken the whole culture of cryptography. It's a very dumb game to play and at the end of the day it does nothing. However, many of the ICO and AltCoins are simply Shillcoins and Scamcoins that serve to help somebody or a community rather than showcase a technology. For all altcoins, I'm sure Bitcoin is like a grandfather and won't be replaced with anything else, but I never put anything on BTC.
