The top 3 altcoin that I suggest we invest now is Stellar, EOS and Cardano. These are great altcoins, they are very promising. Stellar's rapid price increases, it has overcome many altcoin. EOS has a fast transaction processing speed, free transaction costs, I believe EOS will grow strongly and become the biggest rival of ETH. Cardano has a team of professional leaders, it has perfect technology, good scalability. Cardano is really worth it for us to invest.
