Many argue that one of the altcoins can probably in the future beat Bitcoin and be number 1 in CoinMarketCap. I believe Bitcoin will be never beaten by any altcoin, especially centralized one, because Bitcoin is decentralized, is the first crypto currency created, and worshipers of Bitcoin will increase over the time.
If another Bull run happens, Media will only talk and focus on Bitcoin, new comers in crypto will learn about Bitcoin first and foremost.
I believe in crypto. But I worship Bitcoin. And all the coming bull runs will be led by Bitcoin.
There are elements of truth in what you have posted and it will be very difficult for a new coin or any of the existing one to be able to overtake bitcoin in terms of market capitalization and pricing. We can really see clear by looking at the past performance oF bitcoin, it has given a wide gap between it and other coins and when mainstream media community are talking about blockchain technology there first talked about bitcoin and most times never remember to mention other cryptocurrencies. Bitcoin has find it ways into the heart of people and it will be difficult to be overtakes by another coins.
