ethereum, litecoin, neo, bnb, cardano is my daily list to be used as an option to buy altcoins. I have felt from some of these altcoins where the altcoin provides a large profit in investment.
trust me cardano, ethereum and litecoin will give you a surprise for this year, if not possible no later than mid next year. I just focus on investing in them, I will buy more 3 assets and sell my other altcoin assets.
If I am given the opportunity to choose; then Cardano, Stellar, and Ripple are the main choices. After that, Daps and Zilliqa in my opinion have very good prospects
