I love Bitcoin, despite its price is down in this year or even for a long time. When some altcoin as Ethereum, Cardano or Litecoin compete in technology field, Bitcoin is still a king of cryptos.
I prefer Ethereum, with a more reasonable value for small transactions. Although I also have several coins that I feel have great potential in the future, like UB coin and Cashaa.
Why don't I talk about Bitcoin here, because bitcoin is the king of all the coins that have the biggest market share, so bitcoin is definitely a favorite coin for many people.
