how do you think, will the XRP replace BTC and has a very high value of $ 20K like BTC in 2017?
No, XRP will not able to replace bitcoin right now or 5 years on future, when some company will implement them payment into cryptocurrency, bitcoin will be first. second line is ethereum and third line is BNB. ripple going to fourth line.
I also think that bitcoin will still exist and be able to compete in the market because bitcoin has become popular and many people believe in the value of bitcoin. I think ETH and XRP will remain under bitcoin.
