I just purchased an eBook online from America. I needed to use American dollars and I had Australian dollars. I decided to use PayPal because I had just installed it on my phone and set up an account. I went through the motions, purchased the book, and then afterwards realized that PayPal charged an exchange rate of 0.90 when a simple Google search revealed the exchange rate to be 0.94. PayPal ripped me off! I will see if I can change PayPal setting so that it charges my credit card in US dollars and supposedly the rate charged by the card is not so bad, but if this turns out to be too hard then I will just uninstall PayPal and in rage will never use it again. Credit card is already quite safe anyway. PayPal charges absolutely outrageous fees. Not only are their foreign exchange rates a rip off but supposedly if you transfer money to a friend who also has PayPal, you must pay a 2.3% fee. What a rip off! Bank transfers are free. If you don't feel comfortable giving away your bank account number (research what happened to Jeremy Clarkson when he gave out his bank account number on TV) then bitcoin fees are less than 1%.
