I think XLM is in a good position to overtake XRP as long as it heads into a world of commerce driven by decentralized public trade.
As soon as it regulates, it will no longer serve any purpose beside remittance and fiat. And there's no reason to believe that XLM will be the front runner without the undermentioned.
What was the other crypto to enable decentralized public trade? well, try to polish that stone a little bit and encourage the freedoms we are currently without and are enabled by XLM.
