To be honest, nobody isn't a fan of bitcoin, the mother of crypto and the first of it kind, bitcoin will always remain the biggest and nothing can change that, some altcoins are also good but everybody loves bitcoin. still anticipating for Libra though.
What makes you say that?
I am a fan of bitcoin! Yes, some altcoins like ETH or Dash are also good but they couldn't reach the height that bitcoin has reached so far! The idea of blockchain was first implemented in bitcoin. Then the developers from around the world starter creating their own cryptos by tweaking the original idea of blockchain and bitcoin!
Libra is not a cryptocurrency! They are backed by fiat and doesn't offer privacy similar to any other cryptos! Libra is not even in the same league as cryptos!
