Not only are cryptocurrencies suffering lately, but so are exchanges. And it’s nothing new.This list from BraveNewCoin.com, gives the scoop.
Crypto Exchanges That Went Under
11 years of failed crypto exchanges
Thodex – In mid-April 2021, major Turkish cryptocurrency exchange Thodex went offline and its CEO Faruk Fatih Ozer, was reported as missing. Turkish authorities say Ozer had flown to Albania. Albanian authorities arrested two people accused of providing Özer with shelter.
The exchange is now closed with some saying $2 billion in cryptocurrency is missing. Ozer announced over Instagram on April 22nd that what looked to the trained eye like a classic exit scam, was actually a political hit job and smear campaign and that he would be returning to Turkey soon to put things right. At the time of writing, he has not returned, however.
In March of 2022, Turkish officials began a probe to indict 21 defendants associated with the Thodex incident. The charges call for tens of thousands of years of prison for the defendants. Key suspects include Faruk Fatih Özer’s brothers Güven Özer and Serap Özer. Güven was Faruk’s assistant.
Turkish authorities have stated they have evidence of crypto-asset movements from Thodex wallets to bank accounts controlled by the Özer family. Faruk Fatih Özer is charged with multiple violations including the use of information systems and the use of banks and credit institutions to fund a criminal organization. He faces up to 40,564 years in prison. Özer remains at large.
Africrypt – In April 2021, Africrypt founders 21 year-old Raees Bilal Cajee and his 18-year old brother Ameer Bilal Cajee disappeared with what’s thought to be $3.6 billion in crypto. The brothers had marketed Africrypt as an “Artificial intelligence-driven trading platform”, where AI super robots traded client’s funds automatically for supposedly high profits. In reality, the operation was a classic ponzi scheme with new investor’s money paying off initial investors. The Cajee brothers fled the country in late April for destinations unknown. In a surprise move, Raees Cajee contacted the Wall Street Journal in late June, to argue that the value of stolen assets was overblown and only around $5 million was missing. He also promised to return to South Africa for a court hearing scheduled for July 19th 2021.
Local media firm IOL has reported that an affidavit has appeared, signed by Raees Cajee on July 19th, 2021. Raees explains in the affidavit that he and his brother had been forced to flee South Africa because of death threats. He also stated in the affidavit that he would keep his whereabouts confidential. “We have had our location tracked, our mobile numbers hacked, and my father was, also, at one stage kidnapped.” He says that they were in hiding in Dubai when he was met with threats to his family in Dubai and his extended family in South Africa. “This appeared to me to be a case of individuals having been contracted in Dubai by disgruntled investors who, no doubt, intended to intimidate and harass us into making unlawful payments,” Cajee said.
It is reported that Cajee’s affidavit bears the stamp of the South African High Commission in Dar Es Salaam, Tanzania, and is dated July 19, 2021. A group of aggrieved Africrypt investors remains committed to pushing for the brothers to faccriminal charges. Sean Peirce, of Durban-based Coast to Coast Special Investigations, who is representing some individuals who lost funds during the scandal says a warrant for their arrest may be made by
authorities. He says private prosecution will be pursued otherwise.
Pierce represents about 35 traders and says that his group has evidence that there was no hack of Africrypt. He says it can be proven that the intent of the incident was to defraud and steal.
The legal team of the Africypt team, however, believes that many of the investors may face issues with presenting their charges. They say some of the aggrieved investors signed agreements to transfer their claims to a Dubai-based entity called Pennython Project Management, which offered payouts to investors who lost funds during the incident.
Pennython has apparently paid out some of the investors a portion of the funds lost. The group has publicly said it will payout 70% of the lost crypto in Rand to burned investors and appears to have fulfilled a part of this commitment. They say they are doing this because they are interested in the proprietary software belonging to Africrypt. Pennython’s role in the debacle is dubious and with the Cajees still at large, there is speculation that Pennython is connected to the brothers.
[Coinbene](https://coinbenevip.zendesk.com/hc/en-us/articles/4410288775577-Withdrawal-announcement) – The controversial Singapore-based exchange appears to have closed its doors for good. six months ago, an announcement was sent to users which explained that ‘Due to the maintenance of CoinBene global server, there is a problem of unable to log in on the www.coinbene.com page. We are very sorry about this.’ Apparently the maintenance issue was so large that users were invited to withdraw their assets. Users could submit claims after submitting personal information via a survey hosted on a 3rd party site. There were two 4-hour windows when
employees could withdraw funds, however, these were closed on November 30th. Coinbene is noted for the enormous volumes it reported when it ran trade mining programs in 2019 and for a seemingly suspicious US$105 million hack the same year. Coinbene was listed as an exchange faking considerable volume in the Bitwise Asset Management: Presentation to the U.S. Securities and Exchange Commission.
[SaBi](sabiii.com) – Nigerian exchange SaBi, which was notable for being one of the first exchanges in the crypto mad country to list DeFi tokens, is no longer accessible. Trying to access the SaBi website now (sabiii.com) brings up an ‘Error code 1020’ message. A message on the error page reads “The site owner may have set restrictions that prevent you from accessing the site. Contact the site owner for access or try loading the page again.”
MyCryptowallet – Liquidators have been brought in to wind up Australian exchange MyCryptowallet. The exchange was established in 2017 and had 20,000 users. In December, angry users of the platform began to complain that they could not access funds and reported large losses on social media. MyCryptowallet’s issues appear to have been driven by the collapse of technology partner Blockchain Global. What has particularly infuriated investors is that the collapseoccurred just after the price of Bitcoin and other cryptos hit all-time highs.
[Polonidex](https://twitter.com/polonidex) – The decentralized branch of popular CEX Poloniex was officially decommissioned on December 31st 2021. A message on the website explains that the decision was made because of ‘changes in business strategy’. Following the decommissioning date, users could no longer login, post orders, or cancel orders. Polonidex was previously known as TRXMarket and was an exchange that ran on the Tron network and was for some time the main exchange of the blockchain. It has since been replaced by platforms like Sunswap.
[Braziliex](https://braziliex.com/) – In May 2021, Brazilian cryptocurrency exchange Braziliex announced that it would be closing its services after four years of operation. The exchange explained that the decision to close was made due to an environment of greater competitiveness and lack of regulation. “We believe that the risk of operating in this environment becomes even greater in view of the entry of new competitors, as well as the existing uncertainties due to the lack of regulation”, the exchange wrote. The closing of activities was initiated on June 25th of 2021 and this was the last day that users were able to withdraw or deposit on the platform.
Livecoin – Russian based exchange Livecoin announced on January 16th 2021 that it would be closing as it could not recover from a cyber attack that occurred on December 23rd. During the attack, hackers gained control of Livecoin’s infrastructure and modified exchange rates to temporarily inflate prices to unreasonable levels. Once the exchange rates were artificially modified the hackers began cashing out the accounts for easy profits. In a post on Livecoin’s main page, the exchange said it lost control of its “servers, backend and nodes.” Exchange customers will have until March 17th 2021 to claim refunds.
Negocie Coins – As of December 2020, Negocie Coins, a Brazilian exchange that was an onramp for Brazilian Real to crypto trading is no longer accessible to users. The firm’s operators, investment firm Bitcoin Brazil, have been served with multiple lawsuits from clients across Brazil who claim that they have been unable to withdraw funds deposited to the group’s platforms.
CryTrEx – The Italian exchange announced in September 2020 it would be closing. The operators said “After more than 3 years of service, crytrex.com has been closed for bankruptcy, due to the continuous attempts of hacks and hacks that have damaged the financial statements of several users. This had a negative impact on resource
management and it was not possible to continue with our service.” Crytrex was an entry level exchange that accepted deposits via credit cards.
NLexch – Netherlands based NLexch also announced its closure in September 2020 because of costly new regulations. In a statement the exchange said; “De Nederlandsche Bank demanded that every cryptocurrency business should register with them. The registration is deemed to be mandatory, and businesses that failed to comply will be forced to close down operations in the country, the fees charged in the whole process are very expensive. The cost of providing the required level of security, support and technology is not economically feasible on our own.”
Tradesatoshi – UK based platform Tradesatoshi announced in late February 2020 that it would no longer be accepting deposits and that traders must withdraw their funds by March 1st, 2020. It explained in a post that the exchange had reached a point of operation where it was “no longer economically feasible to continue to provide the required level of security, support, and technology.” In order to withdraw funds from the platform, users had to go through an additional set of AML/KYC requirements.
FCoin – Chinese exchange and trade mining adopter FCoin closed for trading in February 2020 revealing a shortage of up to USD130 million of crypto assets. The exchange explained that it had fallen short of paying its liabilities and that issues arose on the exchange because of internal system errors, not a hack or exit scam. The exchange is not currently operational and founder Zhang Jian explained in a recent Reddit post that the company is in the process of attempting to compensate users for lost funds.
Coinnest – The South Korean exchange terminated services in April 2019 after announcing on its website that it had struggled to cope with changes in the cryptocurrency and blockchain industry. In April 2018 the CEO of the exchange and another executive were detained in connection with the alleged embezzlement of assets after apparently stealing customer funds. The platform also reportedly lost $5 million in Bitcoin (BTC) and other cryptocurrencies after making a mistaken airdrop in January 2019.
Cryptopia – In January 2019 the New Zealand based exchange suffered two hacks over two weeks. On January 15th, 2019 the Cryptopia Twitter account announced that the trading platform had suffered a major security breach resulting in “significant losses.” Trading services were suspended and a police investigation was launched. This led to a lockdown and a physical investigation of the company’s headquarters the following day. The hack saw over 70,000 wallets compromised and over US$23 million in Ethereum (ETH) and ERC-20 tokens stolen. A second hack occurred on January 28th, where an additional US$284,000 from 17,000 wallets was captured. In May 2019 it was announced that the Christchurch based exchange had gone into liquidation. An investigative report by a local media outlet Stuff suggested that there were personal conflicts and tensions between the Cryptopia founding members and executive teams. To date, no one has been charged over the theft. The exchange is currently in liquidation with the process of reconciling lost assets assigned to Grant Thornton. However, in August 2020, disgruntled victims of the failed exchange hired New Zealand law firm Chapman Tripp to take on exchange liquidators Grant Thornton for what they say has been a failure by Grant Thornton to comply with its duties as a liquidator under the New Zealand Companies Act.
QuadrigaCX – one of crypto’s most unusual heists. Following the mysterious death of its founder Gerald Cotten in December 2018, the Canadian exchange explained that it could no longer gain access to any of the cold wallets where customer funds were allegedly stored. As investigators began looking into QuadrigaCX’s finances, six cold wallets were identified as belonging to QuadrigaCX. But it was later revealed that five of them had been emptied around April 2018. Recent investigations have stated that a large portion of QuadrigaCX’s losses occurred because of Cotten’s “fraudulent conduct” and that the exchange was run like a Ponzi scheme with Cotten using other client deposits when faced with shortfalls in assets to satisfy client withdrawals. Recent figures from the Ontario Securities Commission suggest the exchange owes over 76,000 clients a combined $215 million in assets and Ernst and Young, the bankruptcy trustee, has so far been able to recover or identify just $46 million in assets to pay out to clients.
Zaif – Japanese exchange Zaif , was hacked for ~USD60 million worth of crypto in September 2018. It first reported an unusual outflowing of funds on the platform on September 14.

Coinsecure – In April 2018, the ironically named ‘Coinsecure’ was hacked for 438 BTC worth ~USD3.5 million. Located in India, the hack is believed to have been an inside job with the exchange’s CSO Amitabh Saxena implicated in investigations. The exchange is not currently operational.
Bitgrail – 170 million USD worth of Nano was stolen from Italian exchange Bitgrail in February 2018 and bankruptcy followed soon after. Founder Francesco Firano has been sentenced by Italian courts to return as much of the assets to his customers as possible in January 2019. In the same sentence, it was declared that millions of dollars in cryptocurrency assets were seized from Bitgrail’s exchange accounts and had been moved to accounts managed by trustees appointed by the Court.
Coincheck – In January 2018 Japanese exchange Coincheck was hacked for ~523 million NEM valued at USD533 million at the time. Hackers initially managed to spread a virus through email that then allowed them to steal private keys. The NEM was stored in a single hot wallet and did not use the NEM multisig contract security recommended by the developers. Months later it had been suggested that most of the funds had sold on the darkweb. After being purchased by the Monex group in April 2018, Coincheck reopened in November 2018.
Youbit – A South Korean exchange, YouBit was hacked in December 2017 for an unknown amount but stated to be 17% of the exchange’s asset reserve.

The security agency blamed an earlier attack on Youbit on spies working for North Korea.
BTCChina – The Chinese exchange later renamed BTCC stopped trading in September 2017 following the creation of a new law that made it illegal for Chinese mainlanders to exchange digital money unless they operate offshore.

On September 3, 2012, it was hacked for 24,000 BTC, valued at approximately US$250,000 when the theft took place (worth 288 million in August 2020).

In September 2017, China ordered all crypto exchanges to close.
Crypto-Trade – Not to be confused with CryptoTrade exchange (which has also disappeared), this trading platform, owned by Esecurity SA, was unveiled in March 2013. The platform sold bitcoin-based shares for BTC or LTC, and claimed to issue dividends. However, after claiming to have suffered losses, and unable to pay its expenditures, the company closed its doors in January 2015, never to be seen again.
Bitcoinica – Launched in New Zealand in September 8, 2011, the site suffered a significant financial loss on March 1st, 2012, when a web host had an internal security breach that gave the attacker access to the wallet in which Bitcoinica stored funds. More than 43,000 bitcoins were stolen by the attacker. The operator provided a statement that reserves were sufficient to cover the loss, but on May 11, 2012 Bitcoinica suffered another security incident in which its hot wallet was emptied again, leading to its immediate shutdown. Auckland based receivers McDonald Vague were appointed on the 10th of January 2013. The receivers released their 13th report into the liquidation in January 2019, at which time they stated that any funds for creditors was still dependent on the release of funds from the MtGox receivership.

MtGox – The most famous exchange implosion of them all was the Tokyo-based exchange, Magic The Gathering Online eXchange. Established by Jed McCaleb in July 2010 and sold to Mark Karpelès on March 6, 2011, the exchange was actually built for trading playing cards. At its peak MtGox handled approximately 70% of all bitcoin transactions. Its death spiral began in February 2014, when the company suspended trading, closed its website, and filed for bankruptcy protection while 850,000 bitcoins evaporated from customers valued at more than US$450 million at the time (10.2 Billion today). CEO Mark Karpelès has been arrested by the Japanese police a couple of times for his part in this. In March 2019 he was sentenced to 30 months in jail by a Toyko court, but his sentenced was suspended for four years. The liquidation of MtGox saga continues to this day with the majority of the remaining funds still undistributed as at August 2020.
The Bitcoin Market – On February 6, 2010, the very first bitcoin exchange was established by Bitcointalk user dwdollar. After getting “scammed” by Paypal in June of that year, and subsequently removing the option to accept paypal from the site, the market quickly dwindled into obscurity, and MtGox rose to overtake it. It is not known when their last day of trading was.
The Antonopoulos rule
Soon after the MtGox fiasco came to a head, legendary venture capitalist Fred Wilson said, “We are witnessing the maturation of a sector and part of that will inevitably be failures, crashes, and other messes. Almost every technology that I’ve watched come into a mass adoption has gone through these sorts of growing pains.”
Clearly it has been easy to go bankrupt, get hacked, give in to corruption, or otherwise fail to make a profitable business out of operating a crypto exchange. Hopefully each new exchange failure means the ones that remain are safer and more resilient than ever. That said, no matter how secure these exchanges become, there is a simple
lesson to be learnt.
“The lesson here,” says Andreas Antonopoulos, “is that if you don’t control the keys, you don’t control the bitcoin. Possession is nine-tenths of the law, and in bitcoin, possession of the keys is ten-tenths of the law. If you don’t control the keys anymore, it’s not your bitcoin! That lesson will be learned as many times as it needs to.”
Business Protocols Not Always To Blame
The first thing we always assume when a business goes under is their operational practices were faulty. But that’s not always the case.
