in short ... if you accepted or sell crypto-currency ... you will be banned (delete items and no refund of the pay for item presentation).
you can sell crypto-currency miner ... but with "real currency" (sic!) ... wire, paypal, etcs ...
i want sell book for bitcoin (to pay, not the subject of the book) on eBay ... but they have delete my items because of bitcoin demand to pay mention.
Did you also accept regular FIAT payments via bank wire or PayPal? I haven't seen items get removed because someone accepted Bitcoins as a means of payment there. Which national version of eBay are you using?
