Why xrp ?There are too many coins better than XRP . I needn't to know how to buy it , thanks.
No one cares about your opinion! The OP is asking about how to buy XRP and not your own opinion! As for the OP, check XRP on coinmarketcap and click on the market so that you can see on what exchange sites you can buy it. Create an account on those sites and transfer Bitcoin to biy XRP.
