NFT collector onekiller purchased Bored Ape #7256 for 188 ETH a month ago — at the time worth about $513,000. On June 1, they sold the ape for 0.088 ETH, or $161.It’s not quite clear what happened, but it seems likely that it may have been a listing error. Onekiller had posted and then canceled listings for the ape several times in the past week and as recently as four hours before the sale, all between 250 and 145 ETH, suggesting that they had control of their account and made a mistake while entering the listing value.
