Ebay and crypto don't mix up well. In general anything that involves Paypal and crypto it's a great way to get yourself scammed. A lot of people pay for their crypto stuff in eBay and then they get chargebacks and so on, this has been happening since I got involved in bitcoin back in 2013. There's people even selling fake QR codes that aren't even related to crypto. They literally print some QR codes and claim it's a bitcoin wallet or some altcoin and sell it to people. I mean that is a new all time low, these people have no shame and I don't know why they still keep doing this. eBay needs to improve their monitoring policies for crypto.
