Let me assume you already know ETH is the best altcoin to hold this season since POS switch is coming soon. BNB on the list is great but the hype already died down, I can remember when a token moving to Binance chain will cause pump for the token and in turn cause uptrend for BNB. I will look into ATOM, I had some before but sold all my holdings. I think XRP is missing on the list with regards their project development so far.
