Now a days lot of sites are available to transfer our funds from one payment processor to other. Some of them are legit, but most of them are scams. We must be very careful while transferring our funds from one provider to another one. Make a lot of search and read a lot of reviews about the site before using it.
Recently one of my friend tried to transfer his payza money to paypal and used a third party exchanging site for this purpose. He got an email notification from the etransfer site stated that his money was successful transferred to his paypal account. He tried to check it, but unfortunately he don't have the ability to login to his paypal account and found that it was hacked. He is very much shocked with it and sent a message to paypal using their twitter service and waiting for the reply.
He strongly suspect that the currency transfer site may hacked his paypal account. There is nothing wrong in using this kind of transfer sites, but we must read a lot of reviews and get guidance from the experienced persons to transfer our money from a payment processor to other one, otherwise we will face some unwanted issues like this. Be careful while changing your ecurrency.
