Crypto-Exchange Says It Can’t Pay Investors Because Its C.E.O. Died, and He Had the Passwords.

Crypto-Exchange Says It Can’t Pay Investors Because Its C.E.O. Died, and He Had the Passwords.

After the founder of Canada’s biggest cryptocurrency exchange, QuadrigaCX, died unexpectedly, about 115,000 clients have been unable to retrieve $190 million in holdings — because the owner was the only one who knew the password to access them, the company said.

Gerald Cotten, 30, died of complications with Crohn’s disease while doing philanthropic work in India in early December, according to a post on QuadrigaCX’s Facebook page. The company didn’t announce Cotten’s death until more than a month after he died, and as customers panicked and tried to withdraw their funds, QuadrigaCX’s website went down, and the company went off the grid.

When QuadrigaCX broke its silence a week later, the company revealed it had filed for creditor protection in the Nova Scotia Supreme Court, according to reporting from Coindesk. Evidently, Cotten was the sole person responsible for transferring QuadrigaCX funds between the company’s “cold wallet” — secure, offline storage — and its “hot wallet” or online server, according to court documents. Very little cryptocurrency was stored in the hot wallet for security purposes. Cotten’s laptop was encrypted, and his widow, Jennifer Robertson, and the expert she hired have been unable to access any of its contents. The company had no corporate bank accounts and used third-party services to manage payments and withdrawals.

“For the past weeks, we have worked extensively to address our liquidity issues, which include attempting to locate and secure our very significant cryptocurrency reserves held in cold wallets, and that are required to satisfy customer cryptocurrency balances on deposit, as well as sourcing a financial institution to accept the bank drafts that are to be transferred to us,” QuadrigaCX’s board of directors said in a letter to customers on Jan. 31. “Unfortunately, these efforts have not been successful.”

The debacle highlights the problems with cryptocurrency’s lack of regulation. It’s not issued by a government or controlled through a centralized financial institution, leaving exchanges such as QuadrigaCX with near total control over investors’ assets and making them vulnerable to hackers or other mishaps.

The mysterious circumstances surrounding Cotten’s death have spawned many conspiracy theories, especially on Reddit, where several users have suggested that Cotten is faking his death as part of an exit scam. Some Reddit sleuths and cryptocurrency researchers have looked into QuadrigaCX’s holdings and found activity from accounts only Cotten had access to after the company said he died. But Robertson provided the court with a copy of Cotten’s death certificate, court records show, and Robertson said she and QuadrigaCX’s interim chief executive have been hit with threats and “slanderous comments” by angry customers.

QuadrigaCX had been plagued with legal trouble in the past year: In early 2018, the Canadian Imperial Bank of Commerce froze more than $25 million of QuadrigaCX’s assets after noticing “irregularities” in the exchange’s payment processes. The Ontario Superior Court of Justice took control of the funds, Coindesk reported, and they were returned to the company days before Cotten’s death.

Now, the company is looking into selling its operating platform to stay afloat. Robertson has asked the court for a stay of proceedings to protect the company from lawsuits and buy time while QuadrigaCX tries to access the cryptocurrency tied up in its cold wallets. She also asked the court to appoint international accounting firm Ernst & Young to oversee its dealings while QuadrigaCX tries to recover the lost holdings.

What is Bitcoin?


Bitcoin is a cryptocurrency, or a digital currency, that uses rules of cryptography for regulation and generation of units of currency. Bitcoin falls under the scope of cryptocurrency and was the first and most valuable among them. It is commonly called a decentralised digital currency. 
Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.


  • Fast peer-to-peer transactions
  • Worldwide payments
  • Low processing fees
It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.

Who created it?
Satoshi Nakamoto is the name used by the unknown person or persons who developed bitcoin, authored the bitcoin white paper, and created and deployed bitcoin's original reference implementation. 
The idea was to produce a means of exchange, independent of any central authority that could be transferred electronically in a secure, verifiable and immutable way.
As part of the implementation, they also devised the first blockchain database. In the process they were the first to solve the double-spending problem for digital currency using a peer-to-peer network. They were active in the development of bitcoin up until December 2010.

What is Blockchain?
Blockchain is the shared public ledger on which the entire decentralised distributed peer-to-peer bitcoin network relies. All confirmed transactions are included in the blockchain so that the bitcoin wallet can calculate the spendable balance and new transactions can be verified.

What is Bitcoin technology?


Once you have installed wallet on your computer or mobile device, it will generate your first bitcoin address and you can create more whenever you need one.

A digital signature prevents the transaction from being altered by anyone once it has been signed. All transactions are broadcast between users and usually begin to be validated and confirmed by the bitcoin network within a few minutes and mostly within an hour.
How Bitcoin works?
Bitcoin’s are completely virtual coins designed to be ‘self-contained’ for their value, with no need for banks to move and store the money.
Once you own bitcoin’s, they possess value and trade just as if they were nuggets of gold in your pocket. You can use your bitcoin’s to purchase goods and services online, or you can tuck them away and hope that their value increases over the years. 
How bitcoin is different from traditional currencies?
Bitcoin can be used to pay for things electronically, if both parties are willing. In that sense, it's like conventional dollars, euros, or yen, which are also traded digitally.
Is Bitcoin Legal? 
In most countries, bitcoin mining is legal. Of course, there are legal ways to mine bitcoin, which generally means using your own resources, such as electricity and processing power. In this case, mining bitcoin’s is legal, but you're stealing the resources needed to mine them, which is illegal Click here to know more about.
India: The Indian central bank has issued a couple of official warnings on bitcoin, and at the end of 2017 the country's finance minister clarified in an interview that bitcoin is not legal tender. The government does not yet have any regulations that cover cryptocurrencies, although it is looking at recommendations.
The central bank, however, has barred Indian financial institutions from working with cryptocurrency exchanges and other related services (although this is being contested in the judicial system).
