We all know Doge is the memecoin, So we do know how long this coin will survive in the market. But XRP had a seperate team back up and huge number of investors in real.So XRP will surely survive for the longer period of time. XRP had huge number of supporters and investors compared to the Doge, So in my opinion XRP is far better than the Doge. Only if the Elon musk get his investment to the Doge, We can't sure doge will have long time survival in the market.Many new traders itself choose the xrp for their investment compared to the doge because it's just a memecoin.
I think dogecoin is quite popular among traders, and XRP also continues to do the best in supply and circulation, and both have a percentage change in price, even so both coins are volatile so it is necessary to see these changes in the crypto market.
But XRP is more utility-based, I would put my money on it rather than on DOGE.
Both can be volatile, but not both do have such supporters and funds flowing to them, as was said before.
