Ethereum and BInance coin can also need to be considered by you,since ethereum is more potentioal altcoin than any altcoins and Binance coins got so much popularity in the recent days because people started to use it to get away from the fee on Binance but don't invest for too long in my opinion.
I agree with you about these coins. Now they're worth the money and may be added into the portfolio for short- and middle-term investments! I think they'll demonstrate a positive trend toward growth!
