Yeah I used to sell bitcoins on eBay to be nice, and then I would just rebuy the btc I sold, however they all scammed me, did the same thing said not received even though you could see that it was delivered on the blockchain. And the ones that didn't scam, PayPal reversed all the money I received anyway???. Be careful there are tons of scammers out there. I quit using eBay and PayPal years ago.
