Coinbase Mistake Gave Traders the Opportunity to Sell Crypto for 100x Price

Coinbase Mistake

1

Coinbase Mistake-Whenever some major problem occurs with a crypto exchange, we will be reading about it everywhere the next day.

1.1

This is not a good face for crypto exchanges, so they are always trying to not let the news get out but usually, they fail to do so.

1.2

So it is surprising that today we are not reading about the things that went down on August 30, on Coinbase.

2 Coinbase Mistake

First reported by investfox.com, on August 30, Coinbase had a major technical bug that gave traders the opportunity to sell their cryptocurrencies for 100 times the price. This technical error occurred for those who used GEL (Georgian national currency) as their account currency. Traders who had crypto prices and their account balances displayed in GEL saw that their balances were showing astronomical prices.

So what exactly happened? Coinbase is a US-based crypto exchange that primarily uses USD as the currency on their exchange, but they also allow traders to display balances in different currencies for traders’ convenience. For this, they need to implement exchange rates of different currencies with USD, and that is where the problem occurred. On August 30, the average exchange rate of USD and GEL was 1 USD for 2.88 GEL, so if traders had 10 USDC in their accounts and wanted to sell it for GEL, they should have received 28.8 GEL following the exchange rate. But in fact, traders were able to sell 10 USDC for 2880 GEL.

Here we can easily see where the problem occurred. Coinbase had a technical error that caused the exchange rate of USD and GEL to be set as 1 USD for 288 GEL. This was not present for only USDC, but every single cryptocurrency on Coinbase was priced for 100 times more than the market price. 

Coinbase Mistake

Traders were able to take advantage of this mistake and sell huge quantities of cryptocurrencies on Coinbase for astronomical prices. Most of these traders transferred their cryptos from different exchanges to Coinbase and sold them there. It is not yet known how much money exactly has Coinbase lost following this technical error, as they still remain silent regarding the issue and no comments have been issued. 

On the traders’ side, things are also not as good as you might think. Following these huge deposits, most Georgian banks started flagging the transactions as suspicious activity and stopped accepting any more deposits from Coinbase. This response from banks was really fast and because of that, a lot of traders didn’t manage to withdraw funds from Coinbase. Shortly after this, banks started to freeze accounts that received payments from Coinbase. Reports suggest that this was initiated by banks themselves and not following the request from Coinbase. 

Following these developments, Georgian traders who managed to take advantage of this error became vocal and demanded that their accounts be unfrozen. The main problem here is that banks freeze accounts and not the funds received, so traders can not access other funds they had in their accounts. Another reason for this outrage from traders is that they believe that they have done nothing wrong and the money they made legally belongs to them, and they have quite good reasons for that. 

One reason is that this is a financial exchange, and they were offering to pay certain money for certain assets. Combine this with one of the most famous trading strategies, arbitrage trading, which is when you find price differences between two exchanges and take advantage of that difference to make profits, and we see where they are coming from. Georgian traders believe that they have not done anything wrong and just followed the legal and accepted trading strategy of arbitrage. 

So we still don’t know what awaits these traders. Will they keep the money they made, or will Coinbase manage to convince banks to refund transactions? All that is left for these traders to do is wait for further developments.

Sports NFTs: What are They and Why are They So Popular?

Sports NFTs

Sports NFTs are a growing segment in the non-fungible tokens (NFT) market, enabling sports fans to collect digital trading cards, virtual memorabilia, and more.

Read on to learn what sports NFTs are, where you can buy them, and whether they are worth the purchase.

What are sports NFTs?

Sports NFTs are verifiably unique digital assets created on a blockchain to represent digital trading sports cards, sporting moments, digital memorabilia, and other types of sports items. 

The issuance of sports NFTs provides an opportunity for athletes, clubs, and sports brands with a new monetization avenue while enabling fans to connect with their favorite clubs and athletes in a new way.

For example, owning limited edition virtual memorabilia of one’s favorite basketball team or a rare collectible card of a favorite baseball player is something that a lot of fans are willing to pay good money for. As a result, sports NFTs are often trading for thousands and thousands of dollars (or more), and the value of some of the rarest pieces has increased substantially since they were minted.

Top Sports Card NFT Brands

In addition to famous athletes, like Rob Gronkowski, dropping headline-making NFTs collections, a handful of sports NFT brands have emerged to take the lion’s share of the sports NFT market. Let’s take a look at those.

Sorare

Sorare is a fantasy football trading cards game that enables players to buy, sell, and trade collectible cards. Sorare players act as football managers by creating teams composed of five football players using virtual cards represented as NFTs on the Ethereum blockchain.

Each card represents a real-world football player, and their performance on the pitch affects the score on Sorare.

NBA Topshot

Built by Dapper Labs (also responsible for CryptoKitties), NBA Top Shot is a virtual trading card platform on the FLOW blockchain, officially licensed by the NBA Players Association. NBA Top Shot NFTs are short videos showcasing notable slam dunks, three-pointers, and other exciting game events, called “Moments.”

NBA Top Shot reportedly reached a market capitalization of over USD 1.1 billion in March 2022.

NFL All Day

NFL All Day was released at the end of the 2021 NFL season as a trading card game in a partnership between the NFL and Dapper Labs. The platform allows fans to buy and collect NFTs of players and memorable moments in the NFL.

NFL All Day operates on the FLOW blockchain and at the time of writing had a market capitalization of USD 68.15 million.

UFC Strike

Another partnership that brings trading cards closer to fans is UFC Strike, which was created by Dapper Labs and the Ultimate Fighting Championship. Just like NBA Top Shot and NFL All Day, UFC Strike gives fans the opportunity to collect virtual trading cards based on famous fighters in the form of NFTs minted on the FLOW blockchain.

UFC Strike had a reported market capitalization of USD 7.9 million in March 2022.

Top 5 NFT Marketplaces for Creators to Sell Non-Fungible Tokens in 2022

Top 5 NFT-In some ways, NFTs are similar to Bitcoins and other cryptocurrencies, except, of course, they are non-fungible and non-divisible. The first NFTs were part of the Ethereum blockchain, which stores extra electronic information to distinguish their uniqueness. Other blockchains now also facilitate NTFs. Because of the differing blockchain technology behind particular NFTs, not all NFT marketplaces buy and sell all types of NFT. Creators will often select an NFT marketplace based on whether that marketplace supports a specific NFC token standard. Ethereum has released two standards now: ERC-721 and ERC-1155. Competitor, Binance, has since released standards BEP-721 and BEP-1155. The two “1155” standards differ from the original “721” standards because they allow multiple NFTs to be bunched and transacted together.

  1. OpenSea
Top 5 NFT

OpenSea boldly describes itself as being the largest NFT marketplace. It offers a wide range of non-fungible tokens, including art, censorship-resistant domain names, virtual worlds, trading cards, sports, and collectibles. It includes ERC721 and ERC1155 assets. You can buy, sell, and discover exclusive digital assets like Axies, ENS names, CryptoKitties, Decentraland, and more. They feature over 700 different projects, including trading card games, collectible games to digital art projects, and name systems like ENS (Ethereum Name Service).

  • Rarible

Rarible is a community-owned NFT marketplace, with its “owners” holding the ERC-20 RARI token. Rarible awards the RARI token to active users on the platform, who buy or sell on the NFT marketplace.  It distributes 75,000 RARI every week.

The platform places a particular focus on art assets. Creators can use Rarible to “mint” new NFTs to sell their creations, whether they be books, music albums, digital art, or movies. The creator can even show a sneak peek of their creation to everybody who comes to Rarible but limit the full project to the purchaser.

  • SuperRare

SuperRare has a strong focus on being a marketplace for people to buy and sell unique, single-edition digital artworks. Each artwork is authentically created by an artist in the network and tokenized as a crypto-collectible digital item that you can own and trade. They describe themselves as being like Instagram meets Christie’s, offering a new way to interact with art, culture, and collecting on the internet.

Each artwork on SuperRare is a digital collectible– a digital object secured by cryptography and tracked on the blockchain. SuperRare has built a social network on top of the marketplace. As digital collectibles have a transparent record of ownership, they’re perfect for a social environment.

All transactions are made using ether, the native cryptocurrency to the Ethereum network.

  • Foundation
Top 5 NFT

Foundation is a specialist platform designed to bring digital creators, crypto natives, and collectors together to move culture forward. It calls itself the new creative economy. Its primary focus is on digital art.

In the first blog post on their website in August 2020, they announced an open call for creators to experiment with crypto and play with the concept of value. They invited creators to “hack, subvert, and manipulate the value of creative work.”

Whenever an NFT trades on Foundation, the artist makes 10% on that secondary transaction, i.e., an artist receives 10% of the sales value any time a collector re-sells their work to someone else for a higher price.

5. AtomicMarket

AtomicMarket is a shared liquidity NFT market smart contract that is used by multiple websites. Shared liquidity means that everything listed on one market also shows on all other markets.

It is a marketplace for Atomic Assets, a standard for non-fungible tokens on the eosio blockchain technology. Anyone can utilize the Atomic Asset standard to tokenize and create digital assets and buy, sell and auction assets using the Atomic Assets marketplace.

You can list your own NFTs for sale on the AtomicMarket, and you can browse existing listings. NFTs of well-known collections get a verification checkmark, which makes it easier to spot the real NFTs. Malicious collections are blacklisted.

Tether Fails to Calm Jittery Nerves as Short Sellers Circle

Repeated assurances by the backers of Tether, the biggest stablecoin, that the token is backed by ample reserves and working smoothly haven’t been enough to reassure markets. 

Tether

1

A so-called liquidity pool that allows traders to swap between the three biggest stablecoins still shows an elevated supply of Tether, with the token accounting for 65% of the total as of Friday. That’s an indication that investors remain cautious about holding Tether, said Edul Patel, chief executive of crypto investment platform Mudrex. 

2

USDT is the most widely held and most accessible stablecoin in the world, so it isn’t a surprise that more people hold USDT and have it available to swap for other assets that they want to use for other purposes,” a Tetherspokesperson said in an emailed response to questions from Bloomberg. USDT is the ticker for Tether’s main dollar-based stablecoin. 

On Curve’s 3pool, where traders can swap between Tether, USDC and DAI, Tether’s share of supply stood at 29.9% on May 6, just before TerraUSD started deviating from its peg. That portion jumped as high as 82% on May 12 as the TerraUSD crisis worsened, briefly knocking Tetherfrom its own peg.

While Tether’s share of supply has since declined, it remains far above pre-TerraUSD crisis levels. And it has reversed some of the decrease after the Journal report. The 3pool platform handled about $117 million in trading volume.

Tether has hewed close to its dollar peg since that brief May decoupling and continues to be widely used despite all the questions swirling around it. Over the weekend, for instance, the cost of buying the token with Argentine pesos surged after the nation’s Economy Minister Martin Guzman resigned.Tetherrelies on a reserve of dollars and dollar-equivalent assets to maintain its one-to-one peg with the currency, though the quality of this stockpile has repeatedly been called into question.

Tether files quarterly attestations from a Cayman Islands accounting firm on its holdings, which show that it’s been steadily decreasing its exposure to assets like commercial paper in favor of more liquid instruments like Treasury bills.Bloomberg reported in February that Fir Tree Capital Management was making a substantial short wager on Tether, predicting it could pay off within a year.

Paolo Ardoino

Tether

Tether Chief Technology Officer Paolo Ardoino has repeatedly taken to Twitter to reassure markets since TerraUSD cratered. In a 12-part tweet this week, just after the Journal story was published, he said Tetherhas “never failed a redemption” and has cut its commercial paper holdings by roughly $45 billion, adding: “Tetherportfolio is stronger than ever.”

Sports Betting:Understanding Sports Betting

Understand moneylines

The moneyline is a plus or minus number associated with each team involved in a particular match, and it refers to either how much you have to bet to win $100 or how much you’ll win if you bet $100.

Sports Betting:Example

For instance, if a moneyline is Toronto Maple Leafs -200 and Vancouver Canucks +155, it means you have to bet $200 on the Leafs in order to win $100, or you have to bet $100 on the Canucks to win $155.

Sports Betting:Leafs

The team associated with the minus number (the Leafs) is the favored team, while the team associated with the plus number (the Canucks) is the underdog.

Sports Betting

You can bet on the moneyline for almost every sport

Many gamblers bet on the moneyline in hockey and baseball, because the scores are lower and point spread betting doesn’t make as much sense in these games. However, you can bet on the moneyline for almost every sport.

Learn about point spreads

Point spread betting is more popular in games where there’s a larger gap between the final scores. In a point spread bet, you don’t just bet on whether a team will win, but also whether that team will win by a specific amount.

Example

For instance, if a point spread is Detroit Lions +4, New England Patriots -4, you would bet on whether you thought the Lions would win and if they’d win by more than four points. Again, the team associated with the minus is the favorite and the team associated with the plus is the underdog.

Sports Betting

Understand parlays

Parlay betting involves making multiple types of bets on the same game. For example, if you combined a moneyline bet and a point spread bet on the same game, this would be a parlay bet.These bets often offer large payouts, but they require a great deal of accuracy.
