I sold a domain to this user that he won in NP Auction. Horrible exchange and process. Buyer unwilling to pay up front. Told me it was okay to move on. Buyer came back two days later saying he wanted it and would pay up front. I then gave payment information and he refused to pay asking if I could send the domain first and he pay with Bitcoin (not a listed payment method). Buyer threatened me with negative feedback. I ended up getting the mod team involved. Buyer ended up paying after this. Extremely impatient and rude. Never will deal with ever again. Very sketchy behavior and risky to deal with this user.
Entire conversation attached for prospeptive sellers and buyers to review.
