I am not sure but somewhere I heard they update it once every day. Do the say anything about this on their site?
Well i think 24 hrs but if the rates fell deep they will update it instantly since they might face loss
24Hours which can be annoying because the exchange rate could of been low at current time but there one would be high
1.00 USD = 48.1305 INR (in xe.com) 1 U.S. Dollar = 46.7317 Indian Rupees (in paypal) difference is 1.3988/$ 6 months back the difference were less than 1RS. It seems that due to recession, paypal robbing more money from its clients!
