why would it be worth any more then what you bought it for lol, i tried the same thing when selling mine, for lols i put it up for 14k, ended up reducing it to 10, and getting 9.5k for it in the end
maybe chuck it up for 6.5, if no bites in a fortnight then gonna have to put it down, also depends on how desperately you want to sell it, took me about 1 month or so to sell mine.
