I agree with ethereum and binance coin
But for shiba and doge, I think it's not suitable for me.
eth and bnb were good layer 1 projects which is have demand from its ecsystem and also outside of ecosystem. with two this kind demand price will relatively stable when bitcoin price ranging ,many times these coins become strongest coin in bear trend, for long term while ecosystme growing alot eth and bnb be good assets.
Moreover, ethereum and binance coins have endless demand in the market. So far the ethereum and bsc networks are still the leading ones used by most people in transactions. That's one of the factors and the reason I choose these two coins. Eth and bnb can only be shifted if any coin passes market cap of the two coins, until now eth and bnb are still on top after bitcoin.
