XLM and XRP are also good Altcoins but you should know that XLM and XRP is quite similar about the platform and their purpose. So, the movement of price of both is so similar, if XRP goes up, so does XLM and vice versa. So, I think we should choose one of two and spend the rest of the capital for other good coins such as ATOM, ETH, LINK. And those are also my choice right now.
