XRP has managed in the last few days what most coins /at least/ of the top 50 have failed for a long time. Thanks to its extreme growth, XRP managed to take off from the second place Ethereum for a moment. The report of the planned start xRapid was the first impulse to the growth of XRP. Running xRapid could, however, be another boost to XRP. So i would recommend buying XRP in your case, but it's up to you. But i would do it so that you buy only for 0.5 btc and 0.5 btc to let in stock.
