Not the coins I'd like to have in my portfolio but if I had to, it would be XRP. The reason is simple, XLM is nearly dead and have almost zero progress all these years
The Galactic Milieu likes purportedly dead, the more it drops in price the more for the game ahahaha!
So yes I should make it clear I am biassed by the fact that I actually have a use-case for Stellar; once the Milieu tokens there "take off" it will need more and more and more and more, even if it keeps going up itself, XLM just to build decent buy-sides there for everything let alone to build truly strong robust buy-sides.
If the Milieu ends up having to prop up and "ratchet" up XLM like it has to for so many supposedly-dead coins it uses, so be it.
