If you ask 10 persons in here in which coins you should invest, then you will probably get 10 different answers, because everyone has their personal favorites. As the poster above me already said though, a lot of people are kinda skeptical about XRP. First of all they are basically fully centralized, which stand against the true purpose of cryptocurrencies and then there also is that SEC issue.
I personally think, that you can also look a little further down the coinmarketcap ranking to find good altcoin projects that are already very big and therefore pretty safe to invest but at the same time still have a little more room to grow than the projects that you have listed above. I personally like Cosmos for example, but as always DYOR.
