With my several months of experience in crypto, maybe I will choose altcoins with the choices and reasons that I know, such as:
1. Ethereum, as an altcoin that dominates the market with its smart contracts system which is very popular for all crypto communities.
2. BNB, as an altcoin that is a utility of a centralized exchange and has a neat system if seen until now.
3. Doge, as an altcoin that is very dominant in the Meme coin type, I think Doge is not just a Meme coin but Doge has become a solid investment and payment tool.
Previously I had 2 reasons for the selected altcoins but I added 3 because I seemed to be starting to get interested in the Doge coin.
