Off-topic, still, if you're interested in having any other token different than Bitcoin, please hold till you see BTC dominance getting decreased in number because until Bitcoin holds the majority, nobody will now take interest in alts and you'll not see the alt season soon, or at least till Bitcoin stabilize.

Buy Bitcoins.
Send your BTC to Binance, then buy XRP.
