You can follow the following steps.
- Add Balance using Credit Card at Bitstamp.
The only legal way as such to send an unlimited amount of money to anyone outside India is by credit card.
International bank transfer deposits carry 0.05% deposit fee on the Bitstamp side (minimum fee = 7.50 USD/EUR) and take 2 – 5 business days to credit. USD deposits credited to your USD balance won’t be converted. All other currencies will be converted to the selected balance currency, free of charge.
2. Now you will need to select the correct market XRP/USD.
One more way to buy XRP is first buy Bitcoin fromor , transfer it to Poloniex and then buy USDT first, then XRP from XRP/USDT market.
To buy XRP directly from INR directly, you can use btcxindia website.
I will not recommend the btcxindia website, it’s price too high and can be easily manipulated.
