The way I'm doing it is buying Bitcoin on Coinbase Exchange, and then using Changelly to exchange Bitcoin for XRP. There are some exchanges like Binance, Etc. where you can buy directly with US dollars, but the only ones I found are in China(Binance) and Korea. I'm not too keen on sending my money to a company under an authoritarian Govt. where cryptos are being heavily regulated now. Other exchanges in the US are being overwhelmed by new account requests(Bittrex) and are not accepting new applications currently.
