Bitcoin will always be the dominant crypto because of first mover advantage and store of value. However, in terms
of scalability and smart contracts ethereum appears to take the lead. It has a lot of problems as everyone knows, so
I'm not going to go into it. I'm looking at Cardano, and on paper, it appears to have a bright future. What do others think?
you choose a good altcoin mate,
by the way in my opinion beside cardano i think you should learn about BNB, polkadot and chainlink too
because all altcoins above is ethereum competitors
