I don't think so, Paypal will still the number one payment processor on the world for longer time as Perfect money is not trusted as I think because it may face the end of E-Gold & Liberty reserve at any time due to it's working way, also Neteller and Skrill didn't really cover all the countries in terms of Debit cards, they are just better in FOREX and Betting fields as they support almost all of them while paypal don't.
I think Paypal is out of all this because they depends on a better base which is online shopping while Neteller and Skrill is Favorited when it comes to invest online paypal is still number one in the world when it comes to shopping or transfer money online.
Dear you're right some payment processor not available in Pakistan. PayPal not work in Pakistan verification issues. Skrill is best payment processor for pakistanis neteller aslo available in Pakistan but only PayPal verification issue
every online payment tool that always gives us convenience in transactions or in verification. will definitely have many users. if there is a payment instrument that is very difficult to verify or execute, it will certainly be abandoned by its users. so all the facilities provided will support these payment instruments to be used by users of online payment instruments.
