You're weeks late dude. ETH just recently regained the #2 spot. Probably check Coinmarketcap before posting.

Anyway, while XRP overtaking bitcoin is technically possible(non-zero possibility), I really don't see it happening. In the first place, I don't even know what XRP is being used for right now. If that happened though? Yikes. That's probably when I lose hope in the people in the cryptocurrency space.
Honestly I didn't check the crypto prices yesterday, as I was a little busy overall doing some chores. But, I'm glad to know that ETH is back at its place as the second largest cryptocurrency by market cap. This was a quick change, as days ago XRP was still the #2 cryptocurrency in market cap. Speaking of XRP overcoming Bitcoin in the future, there's a possibility of it happenning if the coin gets pumped in price due to bank partnerships and hype.
Also, Ripple controls a large number of XRP in circulation, which means that they could manipulate prices at their will. As far as I can remember, there was an article around the web (I believe it was from CNBC) which explained that XRP could overtake Bitcoin in market cap if it became worth $7. Considering that Ripple controls XRP, they could easily pump the price whenever they want to.
However, right now, ETH has taken back its place flippening XRP in the process. This is the usual behavior among crypto markets, as sometimes XRP is the second largest crypto by market cap, while ETH becomes third and viceversa. As for Bitcoin, it has remained as the first largest crypto by market cap for a long time. A change in this, will make quite an impact within the crypto space for sure.
Oh please!!!! XRP's market cap isn't even a quarter of Bitcoin's market cap and you are thinking of a possibility that it will overtake Bitcoin as the market leader. Even if you combined the market cap of both Ethereum and XRP you will still see that Bitcoin is still leading the race. But if you think that there will be a shift in the market leader with regards to the possibility of XRP overtaking Bitcoin what I only see is a short term struggle for Bitcoin's price as the market will really be a mess once the king is dethroned in the top spot.
That's certainly true, mate. However, anything's possible since XRP has flipped Ethereum several times. In the event that XRP becomes pumped by hype or by its internal company (Ripple), then it could easily surpass Bitcoin as the first largest crypto by market cap. Even so, XRP is not a cryptocurrency but more of a centralized database controlled by a single entity. It violates every principle of the blockchain since it lacks immutability and it depends on middleman or third parties.
As such, there's a possibility that XRP may or may not last for long depending on the amount of support it gets from people, and mainstream banks around the world. Which leaves us with Ethereum, as the one cryptocurrency with a better chance of overtaking Bitcoin in the future (which is unlikely) in the event that BTC declines in value drastically. Just my thoughts
