I am selling a small item via gumtree. The buyer wants my email address such that they can send me the money. I know that this is the way for me to receive the money, but are there any bad consequences possible? Do I need to link my credit card to my paypal account? Is it safer if I don't have any linked credit/debit cards? Am I safe enough if I give them my email address? They also know my phone number, which was posted on the ad.
