What are your opinions on paypal or bitcoin for online shopping?
They're basically the same when you're only talking about shopping, both pp and btc via bitpay get confirmed instantly.
The main difference to buyer/holder is that paypal can limit your account and freeze your money, where with bitcoin that cant happen.
The difference though is that btc is sometimes in some cases much faster and more secure than PayPal. However, it depends on where, why and how you are using it. However, the bad thing is that BTC isnt used as much as PayPal these days. I want to see more stores and online sites like EBAY accepting BTC. It would be a real change.
