Bitcoin is the mother of all crypto and that won't ever change. The utility of BTC in future will be the digital gold, storage of value, not payments at coffee shops- we'll have different cryptos for that. Lots of people in this space always suggest some kind of battle between cryptos and mainly between BTC and other alts (BCH the most typical example), but I never saw it that way. The only battle is always between crypto and fiat, and all crypto is represented by BTC (nobody can dispute this. you can't ever crash a crypto market by attacking any other coin, nobody would care. The only way to manipulate it is by attacking BTC). I own many many many alt coins, nevertheless I am very well aware that BTC is the king and most likely will remain so for many years to come.
