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.
