For several weeks, an OpenSea loophole has allowed collectors to buy valuable Bored Ape Yacht Club non-fungible tokens (NFTs) at prices significantly below their market valuation. Thus, Bored Ape Yacht #9991 was bought for 0.77 ETH and then quickly resold for 84.2 ETH. The first mention of such a transaction taking place was registered on Twitter on January 1, 2022, and since then, many more were bought at a fraction of their market value.
