Nicholas T. Article from CNBC. Bitcoin exchanges, too, have at times struggled with security. In many cases, exchanges have responded to incidents responsibly. But other bitcoin exchanges have unfortunately proven to be unscrupulous and even fraudulent.
The case of Mt. Gox provides an especially dramatic cautionary tale. As the first functional bitcoin exchange, Mt. Gox enjoyed broad name recognition, and by it came to manage around 70 percent of all Bitcoin transactions. Gox story, suggesting that trading patterns indicate that a Mt. Gox employee, not an external hacker, absconded with the bitcoins.

For one example, we can look at the shuttered Deep Web black market site known as Silk Road.
While in operation from February to October , Silk Road took advantage of the anonymizing network Tor and the pseudonymous nature of Bitcoin to make available a vast digital marketplace where one could mail-order drugs and other licit and illicit wares. Although Silk Road administrators did not allow the exchange of any goods that resulted from fraud or harm, like stolen credit card information or photographs of child exploitation, it did allow merchants to sell illegal products like forged identity documents and illicit drugs.
The pseudonymous nature of Bitcoin allowed buyers to purchase illegal goods online in the same way that cash has been traditionally used to facilitate illicit purchases in person. Article from The Guardian. The end of Silk Road has not eliminated the problem of illicit trade.

Since then, promised deadlines for the disbursement of the bitcoins have come and gone. The next deadline is set for March 31, Fingers crossed. Gox saying he believes he can help recover up to , of the lost bitcoin. He believes the bitcoin ended up in another now-defunct exchange, the Russian BTC-e.
The plan involves recovering the bitcoins from Russian nationals through legal action. The main lesson learned from the Mt. Gox fiasco is that cryptocurrency is a whole new ballpark, far different from the currently known financial world.
Bankruptcy law was not adequate for dealing with the fallout and the shift to civil rehabilitation is an important precedent for the crypto community. Six years have ticked by and people are still waiting for access to their frozen assets. This is unacceptable and serves as a warning to the cryptocurrency community to put better structures in place for when disaster strikes. Of course, the ultimate goal is to prevent those disasters altogether, but hackers get more creative every year.
