Coinbase said its USD Coin would be fully backed 1-1 with USD. It isn't.
Coinbase's USD Coin claimed that there was $1 "in a bank account" to back it, meaning that if everyone hypothetically tried to redeem their USDC at once at any given time, it would be possible. A July disclosure showed that this wasn't true, and that the coin was actually backed by commercial paper, corporate bonds, and other assets. Bloomberg speculated that the FTC might investigate the claim as a possible "unfair or deceptive act or practice".

Although the developers maintain they never stole any money, rumors around what actually happened sank the project.

An attempt to incorporate NFTs throws a wrench into a $40 million domain name auction
Frank Schilling, founder of the Uni Naming & Registry (UNR) held an auction for 23 TLDs (the bit at the end of the domain, like .com or .org). These included
.game, and even
.christmas. The April auction grossed more than $40 million, but as of mid-December the transactions had not been completed. This is because UNR attempted to add some marketing flair to the auction by including NFTs for each of the TLDs, to go to the auction winners. ICANN, the group responsible for much of the domain world, objected to and withheld consent for the transactions, writing "we sought to understand the impact of the transactions on the Domain Name System ('DNS'), including how Non-Fungible Tokens (NFTs) created on the Ethereum Name Service (ENS) were being used, and were involved in the transactions. ICANN repeatedly asked UNR for documentation or other information related to NFTs in the hopes that UNR would provide fulsome and complete responses."

German museum accidentally burns two valuable Cryptopunks NFTs in copy-paste error
An employee of the ZKM Centre for Art and Media in Karlsruhe accidentally sent two of their four Cryptopunk NFTs back to its smart contract address. This is referred to as "burning" the NFTs, because the address is inaccessible and the NFTs are permanently impossible to trade as a result. The employee had copied the Cryptopunks contract address while browsing Etherscan, and didn't realize that was what he was pasting while making the transfer — wallet addresses are long hex strings like 0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb and are prone to errors like this since they are not easily distinguished at a glance. The two NFTs were originally acquired for the museum for approximately $100 each in 2017, and are individually valued at around $187,000 as of January 2022.
CEO of Turkish crypto exchange Thodex apparently makes off with $2 billion in investments
Turkish Bitcoin exchange Thodex halted trading and limited customers' access to their investments, claiming it was to investigate suspicious activity and swearing it was not an exit scam. With an international manhunt now underway for the Thodex CEO, and no sign of the approximately $2 billion that was invested in the platform, it seems awfully likely it was a rug pull.
$80 million taken from EasyFi lending platform

Roll apologized and announced a fund to help those affected, though the $500,000 fund was only a small fraction of the money lost.
A headline-making $69 million NFT sale looks an awful lot like a publicity stunt
Vignesh Sundaresan's $69 million purchase of an NFT by artist Beeple made headlines. However, Amy Castor outlined a few days later that Sundaresan is a business partner of Beeple's, and that Beeple himself owns 2% of the B20 tokens created by Sundaresan's cryptocurrency investment firm. She speculates that money may not have exchanged hands at all, but that Sundaresan and Beeple orchestrated the purchase to artificially inflate the value of the work, increase Beeple's popularity, and draw attention to Sundaresan and his company.

Indie Developer sells commissioned pixel art as NFTs without permission from original artists
Jason Rohrer, developer of the 2014 indie game The Castle Doctrine announced his plan to auction 155 of the digital paintings that he had commissioned for the game as NFTs on the OpenSea platform, without ever requesting permission from the original artists or informing them of his plan at all. In an email, Rohrer told Kotaku that he hadn't asked for permission from the artists to sell the works as NFTs "mostly because having email conversations with 50+ people would exceed my bandwidth as a solo creator." At least three artists asked for their work to be removed from the collection.
An NFT artist changes all images in their collection to photos of rugs to make a point about the value of NFTs
NFT artist "neitherconfirm" created a collection of 26 NFTs of stained glass-style computer-generated art. After release, they changed the art for each NFT to a picture of a rug, an apparent reference to "rug pulls". The artist wrote on Twitter, "Nobody got hurt. It is pretty easy to change the jpg, even if it does not belong to me or it is on auction. I am the artist, my decision, right? A thread from somebody making his living with art irl about the value of NFTs... All discussions about the value of NFTs are meaningless as long as the token is not inseparable from the artwork itself... What is the meaning of creating an unforgeable token on a highly secured network if somebody can alter, relink or destroy your possession? As long as the value of your artwork is reliable on a central service you do not own anything."

The team behind the Meerkat DeFi protocol claimed they had been victims of a hack, but subsequently disappeared from the web after the equivalent of $31 million in Binance Coin (BNB) and BUSD was pulled from the project. Two days later, a developer for the project wrote that the project had been a "test [of] user greed and subjectivity", and aimed to "[help] users realize the potential danger in smart contracts [and] the subjectivity in the audit processes of audit companies." The developer wrote that all victims would be refunded. Some believed that the bizarre "experiment" explanation was to cover that Binance had stepped in to address the scam.
