paypal already became an old fashoin method to pay
Old is Gold, you haven't heard that? Paypal is a very old method of payment. but still paypal is primary payment source of millions of peoples and thousands of online companies and marketplaces.
But when the question of bitcoin come to front then people also do not care for gold and they want bitcoin because the benefits of bitcoin are more higher than any other payment processor and many people are using paypal because on these places bitcoin is not currently available.
No question, paypal is more popular now as banks are accepting it and they recognize, they are also license and follow
the rules of the government, like the KYC thing or related laws.. In bitcoin we do not follow any rules, we are free to do transactions anytime.
Paypal is not popular, but it is safer than Bitcoin trasaction. Yes, they are following govt rules and conditions, and I think they will pay tax to govt. So it is legal in all country. Bitcoin transaction will not give any revenue to govt that is why it is still illegal currency. But if you see the transaction fees and time Bitcoin is far better than Paypal.
