honestly, it might sounds stupid because we all knew that bitcoin is the first cryptocurrency. All other currency pegged their trade on it. bitcoin as we all knew has a purpose. for payment. it's major purpose is for transaction. anything that has to do with payments majorly.
what if a cryptocurrency pop up from nowhere with a huge and multiple purpose other than bitcoin? is there a possibility of another currency taking over the top spot.
In the short time period Bitcoin will remain leader in the crypto world.
Very simple reason for it.
Bitcoin is already well known in the public and still bitcoin is the main entry point in the crypto world for the most users.
In the long term, who knows, everything is possible.
