Do please note that you can only deposit BTC and other non-fiat coins onto these sites. While Coinbase really does offer some very cool features for both beginners and experts, it is hard to believe that the best-funded bitcoin exchange out there persistently goes offline during large sell-offs. Changelly works in nearly every country but you will need another cryptocurrency in order to purchase bitcoins. This would leave you with no way to get your bitcoins back. Chances are that your PayPal is connected to your credit card or bank account, which can be used to buy at much lower fees. Coinbase Popular. Yes, of course!
