In exchange section you will find the many people give option to open the trade in selling with the paypal or skrill or even more options. However, try grab any escrow to sell your bitcoin safely without problem for both the party.
Or else you can use the localbitcoins exchange to sell your bitcoins and recently I see that bitcoin cost with the LBC buyers is show higher than preev or Google price. I am not sure that you are from which country some people will go with the paypal in LBC too. So try to check the other wallet options at there.
