XLM done great so far and XRP instantly moves down. However, when it comes to usage I prefer to buy XRP or ripple because I can use it more than XLM. When I send money through my main wallet to exchanges or vice versa, I always use ripple for transaction since it has only a small fee and fast transaction. However, when it comes to investment I want to stay in bitcoin nowadays. I don't think altcoins can fight in btc dominance. But between them, I prefer to buy xrp than xlm.
