Solana is good option and it has a good future but I don't think XRP is much potential project. It is better to invest on Luna rather than investment on XRP. I'll suggest to avoid Meme coins also if you're are a long time token holder.
Solana and Luna are currently in very good shape, so investors will certainly look at these two coins before buying them to invest, but for XRP I don't think it would be bad if you want to invest at this time, just not suitable for the long term in my opinion.
