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.
We all know that bitcoin is the most popular coin among the others. There maybe altcoins that are also well known, but they can't beat the popularity of bitcoin. Bitcoin also has the highest price among others. And I guess that's the reason why bitcoin still remain the most influential coin. There's no altcoins that have the ability to reach its value up to $20k, only bitcoin can.
