XMR and XRP

monero the best!
XMR is a very good coin to invest, but personally I'm not much interested in investing in XRP as I think it's better to invest in ETH or LTC.
Yes, LTC and ETH are two very good coins than others, I personally still hold ETH and LTC from 2018 ago because I believe that after Halving's moment both coins will be drastic increase. But sometimes there are also people who like to invest with new coins, from a new project. And I think it's not wrong if you are smart at seeing potential projects.
