I agree !
However, depositing with Skrill/PayPal then withdrawal of profits on card instead of wire transfer, to my knowledge is never possible due to AML rules.
Finally, PayPal/Skrill is not even available to every remote countries and when it is, sometimes, the functions are limited. For instance, PayPal in Andorra is limited, meaning that I cannot top it up at all with either card or bank transfer... I can only receive funds from 3rd parties and spend them again through PayPal (no possibility to withdraw them back to a bank account)
Plenty of barriers !
