Most subsequent media coverage of the case has naturally focussed on their colorful online personae. I am not immune. But the details of the case are equally intriguing, because they gesture at the potential and pitfalls of digital currency for criminal activity.
The case against Morgan and Lichtenstein, as detailed in the affidavit, describes a big crime followed by a series of frustrations. After the hack of Bitfinex, in , the stolen bitcoin was transferred to an outside wallet. The government has not said that Lichtenstein and Morgan hacked the exchange; they are charged only with laundering the proceeds of the hack. But it appears that the couple never even tried to launder most of the stolen coins—94, bitcoin, or about eighty per cent of the total loot, never left the first wallet.
The reason? Laundering digital currency is hard. And the level of difficulty rises as the sums grow larger. As I discovered last year, while reporting on state-sponsored North Korean hackers , thefts from digital-currency exchanges happen with alarming regularity. North Korean operatives particularly enjoy hacking digital bourses in South Korea.
As of last April, one exchange, Bithumb, had been raided four times. Exchanges are vulnerable because they often maintain escrow accounts holding coins in so-called hot wallets, which are connected to the Internet.
Last year, Tom Robinson, who is the chief scientist at the blockchain-analytics firm Elliptic, explained to me the appeal of this kind of crime. Give them back to me. But if digital currency creates opportunities for thieves it also presents giant obstacles.
The desired end point of most exchange hacks is to convert stolen digital currency into fiat currency—pounds, euros, dollars. Launderers must also contend with the fact that coins are traceable. The ledger on which trades occur is immutable. It should always be possible to track stolen loot through its digital footprint.
The problem of handling stolen bitcoin is not unlike that of smuggling a Picasso in the trunk of your car. Stealing the painting is one thing; realizing any monetary gain for it is another. Morgan and Lichtenstein seem to have understood some of the dangerous terrain of the crypto laundry. Last year, Robinson, the Elliptic scientist, showed me a visualization of a peel chain.
The diagram looked like an airline-magazine route map, in which several lines sprout from one dot and then converge on another. The affidavit also details how the couple understood other, more sophisticated laundering techniques. One is known as chain hopping. This is when one type of coin is swapped for another—Bitcoin to Ethereum, for instance—to disguise its provenance. The blockchain-forensics firm Chainalysis recently published a report that detailed the growing use of chain hopping, particularly by North Korean criminal groups.
The preferred method is to use what is known as a DeFi decentralized finance platform, which swaps currencies without ever taking custody of the funds. DeFis are not required to have any know-your-customer procedures. According to Chainalysis, in , North Korean hackers used a DeFi called Uniswap to launder the proceeds of a two-hundred-and-seventy-five-million-dollar theft from the KuCoin exchange—one of the largest hacks of any exchange ever.
Morgan and Lichtenstein also allegedly moved coins to AlphaBay, a dark-Web marketplace that was shuttered by police in You can buy pretty much anything you want using digital currency on the dark Web, and nobody cares where you got your funds. But it seems that the sums Morgan and Lichtenstein were looking to launder were too unwieldy to cash out by buying products. AlphaBay was simply a conduit for the stolen coins.
When they attempted to open seven new accounts on one exchange using fake identities, the exchange could not verify the accounts, and froze their funds. Bitcoin was launched in as a decentralized digital currency, meaning that it would not be overseen or regulated by any one administrator, like a government or bank.
Peer-to-peer transactions have fueled the rise of the digital currency world, and bitcoin has been at the forefront throughout. The blockchain is a public ledger used to verify and record these transactions. The issue of security has been a fundamental one for bitcoin since its development.
On one hand, bitcoin itself is very difficult to hack, and that is largely due to the blockchain technology which supports it. As blockchain is constantly being reviewed by bitcoin users, hacks are unlikely. On the other hand, however, the fact that bitcoin itself is difficult to hack does not mean that it's necessarily a safe investment.
There does exist the potential for security risks at various stages of the trading process. Bitcoins are held in wallets and traded through digital currency exchanges like Coinbase. Developers are always improving wallet security, but there are also those looking to access other peoples' wallets illegally to swipe their tokens and coins.
In the transaction process, two-factor identification is commonly used as a security measure. Of course, having the security of a transaction linked to an email address or a cell phone number means that anyone with access to those components can authenticate transactions. If hackers can determine some of your non-cryptocurrency-related personal information, they may be able to infiltrate your transactions in that space regardless. Bitcoin users are assigned private keys, which allows access to their bitcoins.
Hackers can infiltrate wallets and steal bitcoins if they know a user's private key. There have been widely publicized frauds, scams, and hacks that have plagued individual investors and even major cryptocurrency exchanges in their short history. Part of the issue is simply that the technology and space are new. While this makes cryptocurrencies like bitcoin incredibly exciting—and potentially very profitable—investments, it also means that there are those looking to capitalize on security holes before they are corrected.
All bitcoin investors are advised to take proper precautions to best protect their holdings. Your Money. Personal Finance. Your Practice. Popular Courses. Cryptocurrency Bitcoin.

But the good thing was that Bitfinex issued BFX tokens for victims that were redeemable in USD, and hence, most of their investors were refunded their money back slowly and steadily as per the below schedule. Binance is most popular exchange in and on 7th May , Binance was hacked to lose about Bitcoin. However, the team announced that they will cover all the lost funds from their funds and no user will be impacted from this hack.
The hackers used a variety of techniques, including phishing, viruses and other attacks. So the moral of the story is to keep your cryptocurrencies under your control and not on centralized exchanges. I am saying this because most of these hacks happened because private keys were handled carelessly.
But now, there is lots of educational material available about private keys and hardware wallets like the Ledger Nano S. And CoinSutra is a part of that educational endeavor.

While the disappearance of sites like Sheep and Silk Road took a lot of bitcoins with them, that says more about what happens if you dabble in drug dealing than cryptocurrencies overall. The company, which at the time had a near-monopoly on the trade between bitcoins and real money, suffered a catastrophic hack just one week later.
Following the collapse of the first bitcoin bubble, hacking activity died down for a bit. With bitcoins worth single-digit dollars, there was less motivation to steal them. But in the summer of , one of the biggest — in bitcoin terms — scams ever began to fall apart. And unlike much in the bitcoin world, no hacks were needed, just good old-fashioned fraud. Bitcoin Savings and Trust was a bitcoin-based Ponzi scheme , that posed as a virtual hedge fund promising to pay high rates of interest to investors.
In classic pyramid style, only the first people to invest ever saw those rates of return, as the money of later investors was used to pay off early ones. The fund was started in November , and by July users were expressing doubt. But new members carried on joining for another month until August 17th, when Trendon Shavers - the man behind the scheme - announced he was closing it. Over , bitcoins went through the trust, and Shavers creamed off , for himself — returning the rest to investors.
But only those who got in there early. At the same time as Bitcoin Savings and Trust was collapsing, a bitcoin exchange was suffering its own legal troubles. Bitcoinica had already been hacked in March , and lost thousands of bitcoins. In May that year, the company was hacked again; that time, it was a killing blow.
It was the second ever US lawsuit involving Bitcoin. The Bitcoinica story ended unresolved. The company built its service around MtGox, and so, once it shut down in May , the bitcoins it had left stayed dormant in that account while the legal situation was sorted out. Which meant that when MtGox lost all its bitcoins and closed its doors, the Bitcoinica account holders finally lost everything.
The summer of was a bad time for bitcoin exchanges.
