I think the most promising altcoins that is really good to invest with this year are BNB and XRP. Seeing that many project shifted from eth blockchain to Binance smart chain it creates a very huge possibility that it will pump massively. On the otherhand, Even XRP is having its lawsuit against SEC still manage to maintain a very reasonable value in the market and still being part of top 10 cryptos in the market and I have a strong feeling once that XRP when their case, it will definitely fly high to the moon.
