In my eyes Paypal is good but bitcoin is way better because of the fact that you can do way more things with the bitcoin and its also useable globally.
The bitcoin is a lot better than PayPal.
They are both good if you need them both but if you can do it using bitcoin only then it is better to use one currency like bitcoin, bitcoin is way better as it was many purpose, it could be a payment processor online, a currency, and most of all as investment.
