- PayPal
Definitely PayPal. It's pretty much all I use since the places I shop at, this is the second option or the only one they accept from my country of residence. Credit cards aren't nearly as useful since they get rejected half the time for no reason (I'm looking at you Amazon) and overall aren't as convenient.
I did use BitPay as well a few weeks ago though, converting some Steem to Bitcoin to pay. Once everything was setup, it was a pretty seamless experience actually.
