Yes you nailed it. There is no comparison between bitcoin and PayPal as bitcoin has so many features and jargon free which we cannot find in PayPal and cannot expect as well, In other words PayPal is a failure method and Bitcoin is the future as day by day more and more merchants have started accepting BTC and more countries are going cashless so there is a lot in store for BTC which PayPal can never achieve.
hah, do you understand what do you say? Do you have ability to get back wrongly sent transaction? While shopping, can you get your money back?
Also how can you consider bitcoin and paypal in one way? Bitcoin is currency and paypal is operating online payments. Only one thing I can to agree you is that bitcoin is becoming popular every day.
