So don't get it twisted many of us here are well aware of the boundaries and tin line between Bitcoin and other coins and we align our discussion with that from time to time.
Altcoins has sure shaped how the world perceived Bitcoin. They thought BTC was going to be a scam until now when it is about $30k. Other companies thought it wise to follow the footprint set by BTC and though volatility can crash many of these altcoins in instant, the gains from having to trade them quite doubles or triples what BTC stands to make. Hence why traders preferably use altcoins more for trading purposes and BTC for saving/HODLing.
