Bitcoin

 

The majority of people who own and use Bitcoin did not obtain their tokens through mining processes.They instead purchase a.sell Bitcoin and other digital currencies on any of the many common online marketplaces called "Bitcoin exchanges." Bitcoin exchanges are completely digital and as with any practical organization, are at risk from hacks, malware, and other functional bugs. If the criminal gains access to the Bitcoin person's computer hard drive and steals his personal encryption key, he will transfer these stolen bitcoins to another person. (Users will prevent that if bitcoins are stored on a machine that is not related to the Internet by opting to have a paper case made by printing out their bitcoin private keys and addresses and not holding them on the machine at all.) Hackers will also direct Bitcoin exchanges, earning access to thousands of reports and digital wallets where bitcoins are stored. One particularly infamous hacking occurrence took place in 2014, when Mt. Gox, the Bitcoin transaction site in Japan, was pushed to close after billions of dollars' worth of bitcoins were stolen.
