Love it or hate it, PayPal is pretty damn convenient and this means it's not going anywhere for now.
Conversely, getting BTC is pretty inconvenient in comparison, and until this changes PP will continue to dominate the online payment industry.
Exactly. Plus bitcoin transactions can't be disputed. That's great if you're a merchant or a criminal, but if you are the poor slob who had your BTC stolen (or the merchant didn't deliver after you paid) you have no recourse.
At least a credit card company will help you get your money back if you get taken for a ride by a shady merchant.
The credit card companies and banks only help because they have a stake in it as well. One loses money to them on a regular basis for charges on this or that. So it's not really all that different from losing on a bad deal every now and then.
